General Storage and transport Storage • Rigidur gypsum fibre boards must be stored horizontally on a flat surface (pallet) or on timber logs with a distance of max. 350 mm. • On storing of the boards the bearing capacity of the storage area must be considered (e.g. one pallet / 70 pcs. of Rigidur 10 construction board weighs approx. 1.2 t). For detailed information see IGG data sheet No. 1 "Conditions on building sites". Horizontal correct storage of Rigidur boards • Rigidur boards and accessories must be protected against the impact of weather as well as against sunlight. Board carrier for easier vertical transport. 14 Transport • Rigidur gypsum fibre boards are carried vertically or with suitable means of transport (lifting truck or platform truck). Protect Rigidur boards against humidity and weather Rigips-Tips • In general Rigidur gypsum fibre boards, joint filler and bonding agent should be stored on a dry place inside of buildings. • Rigidur gypsum fibre boards, which have become humid for a short time due to improper storage, must be completely dried on a horizontal surface before installation. • We recommend, however, not processing boards any more, which have become completely wet. 15 1. General Board processing Cutting • Rigidur gypsum fibre boards can be easily processed with the usual wood and dry-construction tools. For this purpose the boards must be placed on a level surface or on a board stack or a cutting table. • Cuttings can be just done with manual circular saws, preferably with plunger saws with sufficient exhaust. The best possible rotation speed and the type of the saw blade depend on the available saw. • Die Rigidur gypsum fibre boards can also be notched with a knife to subsequently break them on the stack of boards. It is not necessary to use a special notching tool. A standard knife with a break-off blade is absolutely sufficient. Notching on the backside of the board is not necessary either. Rigips Note with edges which are rough due to breaking can only be processed with joint filler and not with glue. Only Rigidur boards, which feature edges with exact cuts, can be processed in glued joint technique. 16 Small cuttings can be done manually. Notching of boards Breaking of boards Recesses • Recesses, like for example for wall outlets in cavity walls or for pipe ducts, must be measured, marked and cut with the cavity wall cutter for wall outlets, or respectively, with a centre punch or the compass saw. • The cutting for pipes and cables should at least be 10 mm wider than the diameter of the pipe or, respectively, cable. Recesses can be done with a cavity wall cutter for wall outlets • The cavities must be closed according to the respective notes regarding protection against humidity and fire and sound insulation. 17 1. General Conditions on building sites Today the installation of gypsum board systems is done on a very high processing standard. To avoid errors and to prevent misunderstandings with regard to the installation of gypsum board systems with regard to the basic conditions on the building site – to thus help to ensure quality – we would like to support you with the following expert recommendations and notes. These statements regarding the conditions on building sites are supported by the "Industriegruppe Gipsplatten im Bundesverband der Gips- und Gipsbauplattensindustrie e.V. Darmstadt"! • Planking with gypsum boards should not be done in buildings in case of a relative humidity of more than 80% prevailing for a considerable time. • After the Installation gypsum board systems must be protected against long impacts of humidity. • Even after the installation in buildings sufficient ventilation is to be ensured. • Filling must only be done, when no more changes of the length of the gypsum boards due to impacts of humidity and temperature are to be expected any more. • For the filling process the temperature of material and room must be below + 5°C. 18 Building in winter • Fast sudden heating must be avoided, since it may cause tension cracks due to changes of the board length. • Direct application of hot or warm air on to the surface of the gypsum boards must be avoided. • Sufficient ventilation must be ensured. Rigips tips • Working with plaster and screed usually cause a drastic increase of the relative humidity. Make sure that thorough and even ventilation is available. • Mineral wool to be installed must correspond to the Ordinance on Hazardous Substances (GefStoffV.) as well as to DIN 18165-1. • Wet screed, melted asphalt and wet plasters should be applied before the installation of the gypsum fibre boards. If this is not possible due to the sequence of the individual trades, at least the joint filling should be done at a later point of time to avoid the formation of cracks in the joint area. 19 20 2. Joint techniques • Joint techniques: butt joint, AK joint technique, glue joint technique, filler joint technique • Processing notes for Rigidur joint filler • Practical tips for special situations (Connections) 21 2. Joint techniques Joint techniques The proper execution of joints and a perfect finish are important for the quality and execution of wall and ceiling constructions of gypsum fibre boards to achieve a best possible smoothness of the wall. Apart from technical and optical requirements which must be fulfilled economic working is of great importance. Depending on the type of application of Rigidur gypsum fibre boards you may choose from various joint techniques: Butt joint, AK joint technique, glue joint technique and filler joint technique. Butt joint The boards can be installed with a buttjoint. In this case no glueing or filling of the joint is necessary. This is possible for example in case of double planking, if the first layer of boards is covered by the subsequent layer. Butt-joints Rigips-Tip In case of double planking the Rigidur gypsum fibre boards are installed with offset joints. The joint techniques described in the following are used for the second layer. 22 AK joint technique The chamfered edges of the boards form a butt joint ➀. Subsequently the self-adhesive Rigidur grid reinforcement strap is directly applied to the chamfered edge: ➁. Rigidur joint filler is applied with a plastering trowel and is drawn off to form a smooth surface ➂. To get a perfect wall surface Rigidur joint filler is applied once again for additional smoothing of the wall ➃. 1 Butt jointed AK-joints 3 Filling of the AK-joints with Rigidur joint filler 2 Application of the self-adhesive grid reinforcement straps 4 Additional filling of the Rigidur AK-joint for perfect smoothness of the wall 23 2. Joint techniques Glue joint technique The boards are glued with Rigidur Nature Line or Rigidur Joint adhesive. Only absolutely straight board edges, i.e. edges cut at the plant or cut with a guided plunger saw can be processed with glued joint technique. For a perfect glueing of the joints nothing but Rigidur joint adhesive must be used. The joint adhesive is applied in "caterpillar form" onto the clean, dust-free front edge of the board to be installed, but never onto the base-structure ➀. 1 Application of the joint adhesive to the exactly cut edge 2 The next board is pressed to the joint adhesive, with the width of the joint amounting to a maximum of 1 mm ➁. max. 1mm On pressing together of the boards the joint adhesive must completely fill the whole joint. When the glue is hard the excessive material will be cut off smoothly with a trowel ➂. The consumption of joint adhesive amounts to approx. 15 ml per metre of joint. Rigips Notes • Rigidur Nature Line Joint adhesive is an environmental friendly, one-component glue without solvents and dangerous matters. • Approx. 20 m2 can be processed with one cartridge. • The processing temperature amounts to between 7 and 25° C. • It is absolutely imperative to follow the processing instruction on the packing material of Rigidur Nature Line Joint adhesive.. 24 The subsequent board is pressed against the joint adhesive; max. width of joint 1 mm 3 Smoothly cutting off of excessive joint adhesive Filler joint technique The boards can be processed with a filler joint. The joint width of the installed boards must amount to between 5 and 7 mm ➀. To achieve a perfect filling the Rigidur joint filler* is to be used. The joint is filled and smoothly cut off ➁. Filling is done without any reinforcement straps. To achieve a perfect wall surface Rigidur joint filler is applied once again for additional smoothing of the wall ➂. 1 5-7mm For the filler joint technique a joint width of 5-7 mm is absolutely necessary 2 * Alternative: VARIO Joint filler Important notes and basic guidelines regarding joint filling • The facade must be closed, wet screed and wet plaster must have been applied, since persisting humidity not only prevents the filled joint from drying but may also cause the joints to swell. • Rigidur gypsum fibre boards, which have become wet, should only be filled when they are completely dry again. • Melted asphalt-screed must have been applied before any filling, since the impact of the heat may cause formation of cracks in the joints area. Filling of the 5-7 mm joint 3 Additional filling of the Rigidur filler joint for perfect smoothness of the wall 25 2. Joint techniques Processing notes for Rigidur joint filler* Preparation • Prepare floor and scaffolding without obstacles • Remove dust from joints and surface • Check surface for protruding connectorsn Mixing The mixing of the joint filler has a considerable influence of the later behaviour of the filler during processing. • Only use clean containers and clean tap water for mixing. • Only mix the amount of filler which can be processed during the stated processing time. • Rigidur joint filler (5 kg) is dispersed in approx. 4 l of water. • Loosely disperse the dry material into the water manually or from the sack, until the little powder islands forming on the surface get soaked with water. This is how to avoid the forming of clots and the right consistency is achieved. • The consistency of the mixed joint filler should be such that the material does not slide down even in case of a turned around trowel (mix a little more stiffly for the pre-filling). Important notes • Never add warm water! • Joint filler which has been mixed too stiffly can be diluted with water. • Don't add additional Rigidur joint filler after stirring (danger of clotting!). • Don't use already setting material and don't dilute it with water either (danger of joint cracks!). • It is absolutely imperative to follow the processing instruction on the packing material of Rigidur joint fillers. Surface qualities The surface must be clean, dry, frost-protected and free of dust. 26 Pre-filling • Put joint filler into holes or surface defects. • Filling of traverse or vertical joints with trowel or smoothing trowel. • Cover screw heads with filler. • Allow filled joints and screw heads to set. Rigips tips • Apply joint filler across the joint. (This causes bubble-free filling of the joint!) • On pre-filling always fill the traverse joints first. Additional filling • After setting of the joint filler remove filler possibly remaining from pre-filling process. • After setting of the pre-filling apply the additional filling seamlessly. Avoid lines. • Additional filling can be done with the same material as the pre-filling. • Apply a slightly thinner filler in wide movements to the point of origin. • Finally smooth the surface with a very flat trowel in straight and fast movements. • Additionally fill screw heads and bad spots. • Grind possibly uneven spots of the filling. • Subsequent lining must only be applied after complete setting of the material. • Don't process with temperatures below approx. + 5° C. Storage • Store under dry and frost-protected conditions. • Close opened packages well and use them within 3 months. Important note Before adding another filling the first filling must be absolutely dry, otherwise shrinkage may occur (joint collapses or is hollow). * Alternative: VARIO Joint filler 27 2. Joint techniques Practical tips for special situations (Connections) Apart from the filling of joints on level walls or of roof slopes there also are filled spots in the area of corners or connections to other construction parts. Filling of connectors Before starting of the filling it must be checked, whether all connectors have been properly sunk in. As soon as the pre-filling of the board joints has been finished, the heads of the connectors are pre-filled. The final processing step is the additional filling – and if necessary grinding – of all connectors during the final filling of the board joints. Corner connections to plaster, etc. In case of connections to plaster, concrete or similar self-adhesive painter's strap should be applied before filling, the latter ensures a straight separation of the different materials. The visible part of the adhesive strap is removed after filling. Corner connections in case of sharp / cut edges Rigidur boards with sharp / cut edges are installed with a joint distance of approx. 5 mm. The painter's strap is used as in case of the corner connections to plaster. The visible part of the adhesive strap is removed after filling. 28 Wall-outer corners with edge protection profile In case of protruding wall corners the Rigips edge protection profile can be filled in. For outer edges which are extremely prone collision, e.g. in hospitals or nursing homes (transport of beds), a special heavy-load collision protection should be installed on planking of the walls. 29 30 3. Connectors and distances • Rigidur drywall screws/clamps • Distances between connectors in case of single- and double-layer wall-, roof- and ceiling constructions • Metal- and wooden base-construction double-layer with fastening to base-structure • Depths of penetration of connectors • Lengths of screws and clamps in base-structure depending on application and requirements 31 3. Connectors and distances Rigidur drywall screws/clamps To fasten the Rigidur-board into the base-structure Rigidur drywall screws or resinated steel wire clamps are used. The especially stable and hard surface allows the fastening points to be as close as 10 mm to the edge of the board without causing the edges to break. Rigidur drywall screws are used on metal base-structures to fasten the Rigidur gypsum fibre boards. On wooden basestructures clamps may be used as well. Clamping is especially fast and therefore very economic. Notes • For fastening of the Rigidur gypsum fibre boards to each other expanding clamps (e.g. Haubold) with a wire thickness of dn ! 1.5 mm are to be used. • The side length should be 2-3 mm shorter than the thickness of both Rigidur layers together. • For detailed information on the sequence of the connectors see the chapter "Non-bearing partition walls, topic screwing". Rigidur drywall screws are used to fasten the boards to the base-structure (metal or wood) and to fasten the boards to each other Expanding clamp Wedge clamp Expanding clamps are used to fasten the Rigidur boards to each other, wedge clamps are used to fasten the boards in wooden base structures 32 33 30/250 Rigidur 12,5 30/200 30/150 30/200 30/150 –/– –/– –/– 35/200 30/150 Decke und Dach Length/Distance mm –/– 35/200 30/200 clamps Wall Length/Distance mm Rigidur 12,5 30/250 30/250 Rigidur 12,5 Rigidur 12,5 30/250 Rigidur 10 Rigidur 10 30/150 30/150 30/150 Rigidur drywall screws Wall Ceiling and Roof Length/Distance Length/Distance mm mm 2.

Connectors and distances Depths of penetration of connectors In case of clamping as well as of screwing it is very important to consider the correct depths of penetration. The clamps, or respectively, screws must neither penetrate too deep, nor must they project, in the letter case filling for a smooth surface would be impossible at the spot of the fasteners. Clamps and screws must either be sunk in level with the board surface or 1.5 mm deep as a maximum. Lengths of screws and clamps in base-structure depending on application and requirement Metal Wood S Drywall screw must penetrate metal profile by at least 10 mm Länge Drywall screw must have a minimum penetration of a nominal diameter of s ! 5 x dn S Länge Wedge clamp must have a minimum penetration of s ! 5 x dn (thickness of wire) 35 36 4. Pre-mixed plaster • Requirements of surface • Flush mounted plumbing and wiring • Installation of wall outlets • Installation 37 4. Pre-mixed plaster Rigidur-pre-mixed plaster is a wall lining of Rigidur gypsum fibre boards 10 or 12.5 mm, which is directly installed to vertical construction parts with Rifix bonding agent without insulation layer. Requirements to subsurface • The surface must be: - free of forming oil - dry - shrinkage free - frost-protected - have sufficient bearing capacity - watertight under heavy rain - protected against rising damp. • Lime plaster or loam plaster are not suitable as surface (remove!). • The brickwork must be flush-jointed. • Fresh concrete must be at least 28 days old and dry before installation. • Smooth surface (e.g. concrete) must be pre-treated with Rikombi Kontakt. • Strongly absorbing surface (e.g. pore concrete) must be pre-treated with Rikombi Grund. • Tiles as well as areas with wall paper or plaster surface are also sui table as surface after thorough checking of the adhesive and bearing capacity, and respectively, after cleaning! Flush mounted plumbing and wiring Before installation of the board all flush mounting plumbing and wiring must be completed. Branch pipes and electric wall outlets must be installed into the wall with a projection of 20 mm (Rigidur 10 and Rigidur 12.5), or respectively, approx. 40 mm (Rigidur 30 PS). 38 300 mm 150 mm m 300 m All flush mounting plumbing and wiring must be finished before installation of boards. Installation of wall outlets Überstand The electric wall outlet is installed with a projection as per wall dry plaster (in case of composite boards accordingly more). The projection is to be planned as per wall dry plaster Installation 1 • The Rigidur gypsum fibre boards, which are cut 15 mm shorter than the wall height, are to be stacked with the backside up on a level surface ➀. Stacking of Rigidur boards with the backside up • Mix Rifix bonding agent and apply as paste stripe on the edge of the boards and as lumps on the surface of the board. The size of the lumps amounts to ap prox. 100 mm, the distance between the lumps amounts to approx. 300 to 400 mm. 2 Application of the Rifix bonding agent Rigips-Tip For installation reasons we recommend keeping the following sequence of installation: 1. installation roof-/lining of ceiling 2. pre-mixed plaster 39 4. Pre-mixed plaster • On the floor there must be a joint of approx. 10 mm supported by distance pieces (e.g. pieces of boards which are removed after drying) (for airing during the setting time) and at the ceilings connection there must be a 5 mm joint ➂. 3 Mixing of the pre-mixed plaster • The boards equipped with Rifix bon ding agent are to be slightly pressed in with a level, or respectively with a squ ared timber and are to be aligned with each other plumb-vertical and flush with a joint width of 5-7 mm (filler joint technique) ➃. 4 Mixing of the pre-mixed plaster 5 • When the wall construction is completely dry it is filled with Rigidur joint filler or VARIO joint filler ➄. • The glue joint technique is not suitable for the Rigidur-pre-mixed plaster, since the setting of the Rifix bonding agent could be impaired. Rigips-Tip Apply Rifix bonding agent in areas of reveals, washing basin, consoles, chimney walls, etc. over the complete surface ! 10 mm. The temperature of chimney walls must not exceed a maximum temperature of 45° C. 40 Filling of the pre-mixed plaster Important notes • Separating joints of construction parts are to be included into the pre-mixed plaster. • Apart from that expansion joints are to be installed at distances of " 15 metres. • Loads ! 15 kg are to be fastened to the load-bearing part of the construction. • Pre-mixed plaster is not suitable for draining of wet walls! • In case of installed Rigidur gypsum fibre boards in the pre-mixed plaster procedure filling must not be done immediately.

Non-bearing partition walls Non-bearing partition walls are subject to the regulations in DIN 4103-1, DIN 18183 and in special approvals. Rigips offers different systems for all requirements with varying base-structure, insulation of cavity or planking. Metal base-structure/installation procedure The metal base-structure consists of galvanized steel sheet profiles (connection and post and beam profiles). Important note The cutting of profiles is done with sheet shears, guillotine shears, nibbler or circular saw for metal – never with a parting-off grinder / Flex, since in this case the corrosion protection will be destroyed by burning. Marking • Mark course of the wall on the floor ➀. • Don't forget planned doorways. • Transfer course of the wall to ceiling. Connection profiles • The Rigips wall profiles UW are equipped with single-faced adhesive Rigips connection sealing and are fastened to floor and ceiling with Rigips nailed dowels with a distance of 1,000 mm ➁. Note See page 56 for floor and ceiling connections. 52 Never cut profiles with a parting-off grinder! 1 2 Connection sealings for sound insulation and fire protection Connection sealings for sound insulation only • Rigips connection sealing felt, d " 5 mm • Rigips connection sealing A1 Connection sealings with fire protection (Mind test certificate!) • Rigips connection sealing of construction material class B2 e.g. felt, d " 5 mm, fill joints with respective joint filler material in thikkness of board • Rigips connection sealing A1, d = 12 mm, b = depending on profile Post and beam profiles • The Rigips wall profiles CW (post and beam) are to be designed in such a way that they penetrate at least 15 mm into the Rigips wall profile UW (connection) which is fastened to the ceiling and are to be set with a gap of 10 to 20 mm ➂. • The shaft distance in case of the Rigips post and beam profiles CW amounts to 500 mm in case of small size and " 625 mm in case of large size Rigidur boards. • The closed side of the Rigips post and beam profiles CW is to be put into the direction of the installation (see detailed figure ➃). Note On installation of the planking the Rigips wall profiles CW are to be chekked for stability in the connection floor profiles. 3 Set CW post and beam to at least 15 mm and leave a gap of 10 to 20 mm 4 Put profiles into the direction of installation 53 6. Non-bearing partition walls Planking 1. wall side • In case of single planking the boards are installed in the direction of the closed profiles and with opposing joints. If traverse joints are necessary they must be aligned with an offset of ! 400 mm ➄. In case of single planking the joints are opposing • In case of double planking the bottom layer can also be installed with a butt joint (see chapter "Joint technique" as well). Note Depending on the respective type of joint proceed according to the chapter "Joint techniques". 54 5 Insulation of cavity • After planking of the 1. wall side and the installation of the necessary cable and pipes in the cavity of the wall the cavity may be equipped with an insulation to improve sound insulation or fire protection ➅. • The cavity must be completely insulated. Make sure that the insulation material does not slide down. Planking of 2. wall side • The planking must be fastened with opposing joints ➆. • The subsequent filling of the board joints, connections and screw heads ensures the final stability. 6 7 Important notes • Separating joints of construction parts of the skeleton are to be integrated into the Rigips plumbing walls. Otherwise expansion joints are to be installed at least every 15 m. • As wall connections the Rigips wall profiles CW are fastened with a distance of 1,000 mm (at least however 3 pcs.). • The beginning of the fastening of the Rigips UW, or respectively, CW connection profiles has a distance of approx. 100 mm from the respective end of profile. 55 6. Non-bearing partition walls Connections to floor and ceiling • The best bottom connection of the plumbing walls is directly done on the raw floor. • A 10 mm edge insulation strap is to be provided for between the floating floor screed and the adjacent walls to avoid the transfer of footfall sound (use A1 mineral wool edge insulation straps in case of fire protection constructions). Installation of plumbing walls on raw floor • If at a later point of time additional plumbing walls with sound insulation requirements are put onto floating floor screed, this part of the Rigips wall profiles UW is to be separated and to be cleaned from any remainders. • The best top connection of the plumbing walls is done to the raw ceiling. If plumbing walls are fastened to suspended ceilings or lining of ceilings, these additional loads resulting from the plumbing wall are to be supported especially. Separation of floating floor screed Supporting of additional loads resulting from the wall 56 Installation of pipe and cable ducts, electric wall outlet, etc. In case of plumbing walls as well as in case of dropped ceilings cavity wall outlets as per VDE 0606 H and plastic-sheated cables (e.g.: NYM) are to be installed as material, since they do not need any mechanical protection. After execution of the one-sided planking, installation of cables may be started: • In case of metal post and beams the prepared H-punches are bent open (see figure on the right). Punches for electric cables should be on the same level if possible. H-Punching in metal post • Should cable harnesses or pipes be in- and beam is bent stalled through the wall, cutting is possible only to some extent in the bars of the Rigips wall profiles CW (max. 1 cut per metre of profile)! • The insulation must not be damaged when the cable is pulled through the opening. Note Max. width/height of the cut = width of the bar (e.g. 75) – 20 mm = 55 mm The profile flanges must not be cut! In case of larger openings the strength of the mineral wool is lost, which has a negative effect on the sound insulation. 57 6. Non-bearing partition walls • If electric wall outlets and switches are to be installed a wall outlet cutter can cut the exact opening. • If electric wall outlets are installed into fire protection walls as per DIN 4102-4 with the respective insulation of the cavity (mineral fibre as per DIN 18651, construction material class A, melting point ! 1,000° C as per DIN 4102-17), the insulation layer which is necessary for fire protection can be pressed to ! 30 mm behind the outlets. If this is not possible, the electric wall outlets are to be embedded in plaster. If the cavities are insulated in any other way, electric wall outlets are always to be embedded in plaster construction material. Note For reasons of fire protection, and respectively, sound insulation electric wall outlets are not installed immediately face to face but offset with regard to the post and beams. 58 Stable installation of electric wall outlets in the plumbing wall Elongation of Rigips wall profiles CW • For wall heights " 5 metre the joints of the profiles of the post and beam constructions are just supported by additional pieces of UW profiles. These profile parts are to be fastened with blind rivets ! 3.2 x 6 mm. These fasteners are to be installed with a distance to the joint of " 40 mm. 1000 If the CW-post and beams for plumbing walls with excess heights are not long enough, they may be easily elongated depending on the height requirements as follows: • For wall heights > 5 metre the profile butts of the CW post and beams are just interlaced with CW profile pieces. These profile parts are to be fastened with blind rivets ! 3.2 x 6 mm, too. These fasteners are to be installed with a distance to the joint of " 40 mm. 1000 Elongation for walls > 5 metre Elongation for walls > 5 metre Important notes • For requirements of sound insulation, and respectively, of fire protection these filler joints must be filled with the respective mineral wool. • The butt joints of the CW post and beam to be elongated must not be at the same height! • The stated max. height of a wall system must not be exceeded! • The overlapping of the profile butts results from the value 10 x width of profile. (Example: CW 50 = 500 mm overlapping on each profile side) 59 6. Non-bearing partition walls Planking • We generally recommend boards for planking that have the same height as the room. This not only improves the physical qualities of the plumbing walls, but also decreases the necessary work and material for cutting and filling. • In case of single planking the joints are to be aligned opposite on the same post and beam. • If planking with room-high boards is not possible, the necessary horizontal joints are to be placed in the upper part of the wall. • If in case of single planked plumbing walls horizontal joints are placed within one planking side, they must have an offset distance of at least 400 mm. • In case of several layers of planking the joints must be offset (250 mm). • Stripes of boards should at least have a width of approx. 50 cm. Installation of boards with opposing joints ! 400 mm Distance of necessary horizontal joints in case of single planking at least 400 mm Distance of necessary horizontal joints in case of double planking: 1. Layer: 250 mm 2. Layer: 500 mm 60 Important notes • In case of single planking: Installation of boards with opposing joints, work in the direction of the closed side of the profile. • In case of double planking: the 1. layer may have a butt joint. The 2. layer can be fastened to the 1. layer independing on post and beam. To ensure perfect filling of the connections for plumbing walls with sound insulation, or respectively, fire protection requirements a minimum joint width must be provided as follows: • Planking to raw floor = 5-10 mm • Planking to ceiling = approx. 5 mm • Planking to adjacent wall = approx. 5 mm Order of fastening of boards with Rigidur drywall screws • The 1. board is exactly aligned plumbed with a level and is screwed from the centre of the first post and beam to the longitudinal edge. • Make sure that the board joints are set at the centre of the profile. • The bottom / top fastening point of the board should have a distance of approx. 100 mm from the ceiling or the floor. 18 27 11 17 26 10 16 25 9 4 24 2 3 19 1 12 20 5 13 21 6 14 22 7 15 23 8 61 6. Non-bearing partition walls • For static reasons it is advantageous to screw in the Rigidur drywall screws with an offset (distance 20 to 30 mm). • The minimum screwing distance to the edge of the boards in case of the edges of gypsum fibre boards amounts to ! 10 mm. • Select the length of the screws so that they penetrate the Rigips wall profiles CW by at least 10 mm (also see chapter "Connectors and distances"). • Screw distances in case of single planking: " 250 mm Offset Screwing Double planking • Screw distances in case of double planking: 1. Planking " 750 mm 2. Planking " 250 mm in base-structure 250 750 Screwing distances for plumbing walls with double planking Important notes • See chapter "Connectors" for additional information for connectors and connector distances for single and double planking. • Do not screw planking to Rigips UW profiles (floor/ceiling connection). 62 Filling in case of double planking There are two versions of double planking possible: 1. The bottom layer can be installed with butt joint and without filling.Subsequently the top planking layer is fastened on the bottom layer independent on the post and beam with expanding clamps or with Rigidur drywall screws 3.9 x 30 mm. Fastening is done all around in every board as well as in a fastening row in the centre of the board. Distance of clamps 150 mm, of screws 250 mm. 2. If both layers are to be screwed into the post and beam the same joint distances with the same board width are to be kept for the first and second planking layer (application for glue and filler joint). Only the same joint distance ensures that the connectors each penetrate the profile post and beam. Important notes • Before installing of the next layer the joint filler of the bottom layer must have set, but need not be completely dry. • To avoid the formation of cracks you may only start filling the joints of the last planking layer, when both sides of the wall are closed and no change of the length of the boards can be expected any more. For further information see chapter "Joint techniques". 63 6.

Non-bearing partition walls Double post and beam walls with metal-base-structure Metal base-structure • Execution: Rigips recommends generally using double post and beam walls as parti tion walls in flats. In this case both lines of base-structures are friction-lock connected with double-side adhesive felt straps over the complete height of the profile. 1. For a fixing of the distance it is recommended to also equip the sides of the Rigips UW profiles on ceiling and floor with one-faced adhesive felts. 2. The CW post and beams are equipped with two-faced adhesive felt straps on the side facing the cavity; however the adhesive side facing the adjacent profile is still kept covered. 3. Now the adjacent profile is pushed in holding it slightly tilted; it is plumbed in, when it has got a stable position on the floor. 4. After uncovering of the adhesive side both profiles are pressed together. • Rigips wall profiles UW: UW 50, UW 75, UW 100 for floor-, and respectively, ceiling connection • Rigips wall profiles CW: CW 50, CW 75, CW 100, distance of post and beam: in general 625 mm • Rigips wall profiles LW: LW 60/60 for formation of edges • Connection sealings: All connection profiles are to be supported with Rigips connection sealings from the back. 66 Insulation of cavity • Choose any insulation for the cavity. • In case of special requirements with regard to the sound insulation and fire protection the insulation of the cavity is to be chosen as per survey of the systems.

Non-bearing partition walls Installation of sanitary objects On mounting of sanitary objects into a plumbing wall the large number of plumbing jobs is economically done directly into the plumbing wall to safe time. Light-weight loads • For light-weight loads, e.g. plain washbasin of a maximum width of 600 mm, the supports for the washbasins can be directly installed into the Rigips wall profile UW (flush with front). Subsequently they must be fastened to the raw floor as well as laterally to the Rigips wall profiles CW (post and beams); they must be permanently prevented from sinking. Ensure that the Rigips wall profile UW permanently rests solidly on the raw floor. Heavy loads Sanitary objects, which are to be regarded as "heavy console loads" are mounted to pre-fabricated, completely welded or infinitely adjustable Rigips carrier posts. These rustproof carrier posts are to be mounted in the wall cavity and support the occurring loads together with the Rigips UA profiles and the planking. • After installation of the base-structure with carrying posts for sanitary objects and after planking of one wall side the plumber may do the installation of the sanitary objects. • Fastening is done with brackets or clamping collars and with the fasteners provided at the carrier posts. • To muffle the noise of running water, the pipe fasteners are separated from the wall base-structure by means of rubbers, felt or similar material. • Pipes for cold water must be padded to muffle the noise of running water on the one hand and to prevent to formation of condensation on the other hand. 71 6. Non-bearing partition walls • For wall-mounted toilets or heavy washbasins the installation of the carrier posts must be safe against setting and flush with the Rigips wall profile UW. – In case of room-high facing walls the wall-mounted toilet must be supported. – An installed, wall-mounted-WC must be connected to the wall in such a way, that up to 400 kg of additional load can be transferred via the basestructure into the massive raw floor.. nstallation of the washbasin post for plain washbasins Rigips-Tip In case of plumbing walls it is recommended to order an insulation of the cavity by mineral wool. Plumbing ducts • Plumbing ducts, e.g. for water pipes, must be cut approx. 10 mm wider than the diameter of the pipe. • Plumbing ducts as well as all connections and edges are to be closed with a plasto-elastic fungicidal sealing compound. • If shower exits are equipped with special plumbing parts (with sound insulating rubber sealing) additional measures will be necessary. 72 Single post and beam walls with wooden base-structure The wooden base-structure consists of: Wood of sorting class S10 as per DIN 4074, residual moisture " 20 %.

Note See page 56 for the connection to floor/ceiling. 74 1 2 3 Planking 1. wall side • In case of single planking the Rigidur gypsum fibre boards are installed with opposing joints. If traverse joints are necessary, they are to be installed with an offset ! 400 mm ➃. • In case of double planking the bottom layer can be installed with butt joint (also see chapter "Joint techniques"). 4 Note Depending on the chosen type of joint proceed according to chapter "Joint techniques". Insulation of cavity • After planking of the 1. wall side and the execution of all electrical and plumbing jobs in the cavity of the wall, the cavity will be equipped with insulation to improve the sound insulation, or respectively the fire protection ➄. • The cavity must be completely insulated. Ensure that the insulation material does not slide down. 5 Notes • In case of wooden walls notching for ducts is possible in the upper area of the post and beam. Mind that in Beplankung 2. Wandseite case of wooden post and beams large recesses for ducts must only be done with round diameter. For this purpose a cross section of at least 15 mm must remain on both sides. • See pages 57/58 for the installation of electric wall outlets, etc. 75 6. Non-bearing partition walls • The planking must be installed with opposing joints ➅. • The subsequent filling of the board joints, connections and screw heads ensures the final stability. 6 Important note Joints separating construction parts of the skeleton are to be integrated into the Rigips plumbing walls.

Installation of door cases • One-piece door cases are installed before planking. • After finishing of the plumbing wall and corresponding doorway multi-part door cases are installed. • The cavity between profile and door case is to be filled with insulation material. If fire protection doors are installed, it may even become necessary to use mortar. Mind the approval certificate of the door. Installation of steel door case – Example with Rigips bracing profiles UA (Insulation not shown) 81 7. Doorways Important note The installation of door cases as well as the insulation are to be done as per the requirements (as per tendering). Mind the installation instruction of the manufacturer of the door cases. Notes for sound insulation Openings for doors or windows have a negative influence of the sound insulation of a separating wall. The requirements of sound insulation as per DIN 4109 generally refer to doors which have already been installed (door leaf including frame and door case). The sound insulation depends on the sound insulation of the door leaf as well as on the quality of the notch sealings, above all on the sealing of the lower door joint. The manufacturers of doors, and respectively, windows have to provide the respective certificates for sound insulation. The influence of areas with low sound insulation like doors or windows on the resulting airborne sound insulation of a construction part can be shown by a method of calculation shown in annex 1 of DIN 4109. ) In this case of the following values are to be calculated: • Ratio of the complete wall area to area of door or window. • Difference between the evaluated degree of sound insulation of the wall and the evaluated degree of sound insulation of the door or the window.. 82 Installation of wooden door case: Example with Rigips bracing profiles UA and wood beams (insulation not shown) Installation of multi-part door case: Example with Rigips bracing profiles UA (Insulation not shown) 83 1) UA 75-20 UA 75-20 UA 100-20 UA 100-20 " 75,0 " 75,0 " 100,0 " 100,0 1 x 12,5 2 x 12,5 see table 1, DIN 18 183 see table 1, DIN 18 183 see table 1, DIN 18 183 see table 1, DIN 18 183 installation sector 2 mm The door post profiles are to be fastened to the floor and raw ceiling by means of connection angels (e.g. plug-angle).

Attic conversion • Attic linings • Wooden base-structure • Metal base-structure • Insulation/vapour retardant • Rigid connections/details • Wall of eaves storage spaces/jamb wall (Metal- and wooden base-structure) 85 8. Attic conversion Attic linings There are the same requirements with regard to the planking material ceiling- and roof slopes as are usually applied to walls. In detail these are the sectors of thermal insulation, protection against humidity, sound insulation and fire protection. For reasons of energy saving it makes sense to insulate and plank the complete roof slope. To fulfil fire protection-related requirements (danger of wetness due to condensation) not only insulation as well as planking but also a vapour retardant will be installed all the way up to the ridge of the roof. Base-structure • Consisting of: Steel sheet profiles, galvanized as per DIN 18182 or wooden laths, sorting class S 10 as per DIN 4074, part 1, residual moisture " 20 %. Important notes Correct installation of system: 1. Completely insulate and collar beam ceiling and roof slope and make them windproof. 2. Screw the base-structure traverse to the rafters/beams of metal/wood. Metal base-structure • Directly fasten Rigips hat ceilings profiles. • Board span (with fire protection): " 400 mm. • Bearing profiles (with fire protection): " 900 mm. Cut metal profiles – with sheet shears, guillotine shears or nibbler, never with parting-off grinder/Flex, since in this case the corrosion protection will be destroyed by burning. 86 X 1 Rigips direct suspender 2 Mineral wool in case of fire protection requirement (mineral wool B1 d ! 100 mm) 3 Planking with Rigidur gypsum fibre boards 10/12.5 mm Rigips Note The fastening of Rigips ceiling profiles CD 60/27-06 in connection with Rigips direct suspender "Klick Fix" is possible.

Important notes Mind the following sequence on installing of the planking: • 1. Step: Planking of ceiling / collar beam layer • 2. Step: Planking of roof slope • 3. Step: Installation of wall of eaves storage space (jamb wall) 87 8. Attic conversion Insulation/Vapour retardant • A vapour retardant is to be installed on the warm side between planking and thermal insulation to avoid increased vapour diffusion. • Choose insulation material in such a way that the insulation mats are pressed between the wooden beams. For this purpose the width of the mats should be approx. 10 mm more than the clear width between the beams. • In this case it is especially important to fasten the vapour retardant air-tight to the beam and the adjacent end wall. Mind the instructions of the manufacturer. Close edges, joints and cracks for example with a suitable adhesive tape. Important notes • In general vapour retardants are also air-tight. In this case it is especially important to permanently seal the connections to adjacent walls and ducts. • See the respective processing guidelines of the manufacturers of insulation material for further details.. 88 Rigid connections/Details • For a correct forming of the valley between ceiling and roof area the board edges of the roof slope should be correspondingly chamfered. • Insert separating strips between the planking of the individual areas like ceiling and slope, slope and wall of eaves storage space or areas, which are adjacent to end walls, etc. They can be painter's strap or some similar adhesive tapes. (adhesive tapes for vapour retardants are not suitable!) The filling of the joints is done against these separating tapes and thus allows a defined separation of the areas where hairline cracks occur. • It is only recommended to seal the edges, if there are sufficiently wide joints between the planking and the plasto- elastic joint fillers can only stick on two sides. Furthermore it must be pointed out that such joints must be renewed after some years.

Ceiling systems • Plumbing ceilings • Lining of ceilings • Suspending systems • Connections (rigid and free) • Installation of Rigidur ceilings • Suspended plumbing ceilings • Directly fastened Plumbing ceilings 95 9. Ceiling systems Plumbing ceilings Plumbing ceilings are suspended from the existing raw ceiling by means of approved suspending systems. Linings of ceilings Linings of ceilings consist of a basestructure of wooden laths, which is directly connected to raw ceiling basestructure, Rigips ceiling profiles CD or Rigips hat ceiling profiles. The anchoring of the base-structure to the raw ceiling in this case, too, is done by construction inspection approved screws or dowels. Dowels or Screws • Dowels must have a construction inspection approval for anchoring of plumbing ceilings as per DIN 18168 with regard to the available surface. • In case of wood surface the screws must be screwed into the bearing surface either laterally or from below (screwing into the facing is not sufficient!). The size of the screws must be sufficient to safely transfer occurring loads into the surface. The screw length depends in this case on the thickness of the suspender to be installed plus the necessary depth of penetration into the surface. 96 Suspending systems Rigips fast-suspender • Approved suspenders are Rigips loop wires or Rigips hook wires with tension springs and respective Rigips fast suspenders, e.g. anchor fast suspenders which belong to the base-structure (laths or Rigips ceiling profiles CD 6006). Rigips fast suspenders allow tension loaded suspended ceilings. • The approved loads per suspender are between 0.15 and 0.25 kN. • The Rigips suspension wire (as per DIN 18168) must at least be pushed 10 mm through the spring of the bottom part. Anchor fast suspenders Important note In case of higher loads/ceiling weights, which may be caused by the thickness pf the planking, Rigips Nonius-systems are to be used. 97 9. Ceiling systems Rigips Nonius-Suspending systems • Rigips Nonius-suspending systems must always be used, when suspensions must be rigid in compression. • Rigips Nonius-suspending systems can bear loads of up to 0.40 kN. • The connection of the adjusting bar and the bottom part of the base-structure is always done with two safety elements. • Suspenders must always be aligned vertically and in such a way, that they connect the base-structure to the raw ceiling without any allowance. Important note If suspenders are not vertical or do not take tension loads, there is the danger of excessive loads and therefore the failure of the immediately adjacent suspenders. Apart from that suspenders, which are not subject to tension loads, may cause the ceiling areas to rattle in case of air circulation (draught, etc.). 98 Base-structures Base-structures may be built from wooden laths with a max. moisture contents of 20 % or Rigips ceiling profiles CD as per DIN 18182-1. In case of plumbing ceilings they always consist of base- and carrying laths, or respectively, profiles. The cross section of the wooden laths must correspond to the following table. Dimensions von wooden laths Base laths mm Bearing laths mm 60/40 or 50/30 50/30 mit 60/40 oder 50/30 60/40 mit 60/40 oder 50/30 Important note Laths for plasterwork are no base-structures! • The connection of the base and the carrying laths can be done with a Rigips drywall screw or with a wood construction screw, or respectively, with two nails per crossing point hammered at a slanted angle. • In case of CD profile constructions the profiles are connected to each other with Rigips anchor angles or Rigips cross connectors. • In case of a level base-structure the Rigips ceiling profiles CD are connected by means of Rigips safety cross connectors. • The shaft distances of the base-structures depend on the Rigips ceiling system; details are to be found in the table below. • Linings of ceilings can also be manufactured from a simple basestructure from nothing but carrying laths, or respectively carrying profiles. Rigips-Tip In case of fire protection ceilings the instructions are to be executed corresponding to the respective ceiling systems of planning and building, and respectively, to the test certificates.

Important note Cross joints and flying joints are not permitted. 100 • Multi-layer planking is to be installed one above the other with an offset of the vertical joints of at least 400 mm. The traverse joints of the top and of the bottom planking, too, must be offset with a carrying lath distance. • The permitted span of the Rigidur boards in case of standard systems is summed up in the following table. Permitted spans of Rigidur boards in case of lining of ceilings and plumbing Board type/-Thickness mm Span mm Rigidur 10 400 Rigidur 12,5 500 Important note The mineral wool layer in the area of the suspended ceiling must be installed depending on requirements and in case of fire protection requirements the respective test certificates must be regarded. 101 9. Ceiling systems Connections Edge connections of plumbing ceilings or lining of ceilings can in general be divided into two categories, i.e. "rigid" and "free" connections. Note See chapter "Attic conversion" for information on "rigid connections" on page 89. Free connections Free connections are edge connections, in case of which the ceiling construction does not have any direct connection to the adjacent construction parts. Such connections are open, or respectively covered shadow gap joints or connections on visible edge angles. Free edge connections are used, when considerable bow of the ceiling or considerable changes of the length of the boards due to high humidity or different movement of the construction parts are to be expected. 102 Installation of Rigidur ceilings • Marking of the heights of the ceiling at the adjacent construction parts by means of a plumb-line or laser. • The Rigips suspenders are fastened to the raw ceiling with the required distances. • In case of the installation of base and/or carrying laths/profiles the offset of possible butts by at least the distance of one suspender is to be regarded. • The first/last carrying profile of the ceiling is positioned with a distance of approx. 150 mm to the adjacent wall. • Cut Rigips profiles (sheet shears, guillotine shears or nibbler) Important note The plumb-line, or respectively laser beam, is to mark the bottom edge of the base-structure and not of the planking, since the coloured chalk may become visible through later surface lamination. Expansion joints • Expansion joints in plumbing ceilings must be aligned at least every 15 metres of field length as well as within the area of the skeleton expansion joints. Additionally they must be provided in case of reductions of areas, which e.g. frequently occur in case of hallways. • The width of the joints depends on the movements of the construction parts to be expected. These movements may be caused by the bow of the ceilings or changes in temperature or humidity. 15m Expansion joints are to be provided at least every 15 metres 103 9. Ceiling systems Installations into plumbing ceilings • For built-in parts e.g. lamps or ventilation outlets with dimensions that are bigger than the clear distance of the profiles, the vents in the ceiling areas must be amended by exchanging of the base-structure. • This also generally applies for built-in parts ! 6 kg. Exchange for additional • The loads of the built-in parts are to installations be integrated into the raw ceiling by at least two additional Rigips suspenders per exchange. Furthermore the number and type of the Rigips suspenders depends on their load class and the additional load to be taken due to the built-in part. • Heavy loads, which exceed the additional load of dowels and ceiling construction, must be directly connected to the raw ceiling or to a supporting construction, which ensures a load transfer into the raw ceiling. 104 Suspended plumbing ceilings Ceiling profiles Rigips ceiling profile CD 60-06 (Alternative with wooden laths) as base, or respectively, carrying profile in connection with suspending systems: • Rigips anchor fast suspender, • Rigips anchor suspender for slotted belt or • Rigips Nonius suspender depending on weight of ceiling. Profile connectors • Rigips cross fast connectors (for heavy constructions). • Rigips anchor angle. • Rigips safety traverse connector or Rigips traverse connector for base-structures of equal height.

Surface treatment Surfaces The contractor who does the final coating of the surface is responsible for the testing of the surface as well as for the use of suitable materials. Pre-treatment • Splashed mortar, filler burrs and similar must be removed from the board surface. • Fillings must be dry and if necessary must be ground to remove burrs. • The complete surface of board, joints and fillings must be equally dry. • The surfaces are to be thoroughly dusted. Primer Rigidur gypsum fibre boards come preprimed, therefore additional primer is only necessary, if the manufacturer instructs you to do so for the products included in his system or if more safety may be necessary for further processing (e.g. in case of thin-wall or textured plasters, paint coatings or tiles). Important notes • For an even absorption behaviour of the gypsum fibre boards and the filler joints we recommend equally spreading of Rikombi Grund over the complete surface according to the processing instruction, if the manufacturer of the paint does not call for any other primers. Allow the primer to completely dry before further processing. • If the manufacturer calls for a primer, mind that it is completely and thoroughly dry, before starting further processing. 110 Coats of paint • All standard paints like emulsion paint, latex paint, alkyd paint and lacquer are suitable as a coat of paint. • Coats of paint on mineral basis like lime, silicate paint, organic silicate paint as well as nitro-compound lac quers are not suitable as coats of paint. Important notes • For a safe result do a trial coating via the width of several boards including the areas of joints. • To reliably prevent possible shining through of colour (yellowing) generally apply a retardant primer. 111 10. Surface treatment Wall papers • All types of wallpapers incl. ingrain wallpaper are suitable. Only use wallpaper paste on the basis of methyl cellulose and/or suitable syn thetic resins. Rigips-Tip Due to the application of wallpaper primer the dry wall paper can often be removed from the Rigidur boards without wetting. Rikombi Grund is suitable as wallpaper primer; it must be applied according to processing instructions. Plaster Textured thin-wall on mineral base or plastic-containing base are suitable for gypsum construction boards; after application of a retardant primer they may be easily applied to the Rigidur gypsum fibre boards. Rigips Note If thin-plasters are applied, the areas of the joint must be covered with reinforcement straps according to the instructions of the manufacturer to avoid possible formation of cracks. 112 Tiles • Rigidur gypsum fibre boards can be tiled with plastic or ceramic tiles without any problem. If the manufacturer specifies the use of a primer, the latter must be applied according to the instructions of use. A sufficient time of drying must be granted. • Flexible thin-bed adhesives applied by means of a notches trowel are suitable as adhesive. Flexible joint mortar should be used for the jointing. Rigips notes • The tiles must not be soaked in water. • The tile adhesive must be completely dry before the tile joints are filled. • Double planking with Rigidur boards or a decreasing of the distance of post and beams of 625 mm is not necessary. • Within the area of showers or bathtubs surface sealings must be of sufficient size. Corners and ducts are to be suitably sealed with sealing straps, sealing collars or similar material. • For the damping of structure-borne noises a strap of felt must be applied between bathtub and planking. Notes: Special applications on areas subject to humidity • Use penetrating primer as well as humidity retardant sealing adhesive e.g. Lastoment 1 (PCI). • In case of wall surfaces a flexible surface sealing or a thin layer of sealing is to be applied all over the surface with tile adhesive. • Close ducts, connections and corners with plasto-elastic joint filling composition to be water-proof. • Use fungicidal sanitary sealing material. • Fittings will be equipped with threaded collars with rubber sealing. 113 114 11. Fastening of loads • Loads on walls • Loads on ceilings 115 11. Fastening of loads Fastening of loads Various loads can be safely fastened to wall constructions of Rigidur gypsum fibre boards with suitable connectors. Low-weight items can be fastened with simple picture hooks. Depending on the type of fastener a variety of different normal vertical loads can be fastened. 1 2 3 Approved vertical loads on planking1) Planking Rigidur 10 mm Rigidur 12,5 mm Rigidur 10 + 12,5 mm Hook 1 15 kg 17 kg 20 kg Hook 2 25 kg 27 kg 30 kg Hook 3 35 kg 37 kg 40 kg 1) Maximum loads depend on type and quality of the wall hook. Approved loads on cavity wall dowels and threaded screws Shelves and wall-cupboards can be easily fastened with cavity wall dowels. Here the approved max. load of the wall construction must be taken into consideration. Console loads can be fastened to Rigips construction parts with standard fasteners on arbitrary parts of the planking. The choice of the suitable fastener on the one hand always depends on the depth of the load t (in case of walls) and on the other hand on the weight of the load to be fastened. 116 Approved loads on cavity wall dowels and threaded screws in case of a load depth of 300 mm Planking cavity wall dowel1) Threaded screw1) ø 5 mm Rigidur 10 40 kg 20 kg Rigidur 12,5 50 kg 30 kg Rigidur 10 + 12,5 60 kg 35 kg 1) Safety factor 2 Molly-screw anchor (cavity wall dowel, e.g. Hilti HHD) threaded screws Important notes • In case of using of dowels mind the dowel manufacturer's processing instructions. • The distance between 2 fastening points must at least amount to 150 mm, otherwise only half of the bearing load applies per dowel. • The total of the individual loads must not exceed 150 kg per metre of wall. Heavy console loads • Heavy console loads are fastened to the base-structure. Sanitary elements must generally be fastened to special carrier posts or travers beams. • In case of wall linings on massive surface (e.g. wall dry plaster) console loads are to be directly anchored into the massive construction part with the respective connectors. 117 11. Fastening of loads Loads on ceilings Built-in parts like lamps, etc can be fastened to Rigidur ceilings wherever you like. For this purpose there cavity dowels for ceiling constructions or special tilting dowels and spring unfolding dowels of metal available. Fastening of loads on lining of ceilings Lining Tilting or spring unfolding dowel Rigidur 10 20 kg Rigidur 12,5 25 kg Rigidur 10 + 12,5 30 kg Important notes • In case of using of dowels mind the dowel manufacturer's processing instructions. • The distance between 2 fastening points must at least amount to 150 mm, otherwise only have of the bearing load applies per dowel. • Heavy items must be fastened to the base-structure.

Special applications Outside applications Rigidur gypsum fibre boards cannot only be used for dry inside constructions but also for outside applications e.g. for the building of non load-bearing wall and ceiling constructions in multi-storey car arcades, passageways and roof projections. Conditions for the planking with Rigidur outside • Direct impact of water, e.g. rising humidity, driving rain, rain or snow must be excluded. • Direct solar radiation or heating to more than 50° C is to be avoided. • In case of double planking the fastening of both layers must generally be done in the base-structure. Rigidur Beplankung Example for application: Roof projection with Rigidur Connectors and distances Rigidur drywall screws as well as construction supervision approved connector of stainless steel are approved. It is absolutely necessary to fill the screw heads. Mind in case of the fastening that the average connection distance in case of screws is reduced to 150 mm and in case of clamps to 100 mm. Important note It is absolutely necessary to fill the screw heads. 122 Base-structures • Metal, or respectively, wooden base-structure are to be treated with respective corrosion protection, or respectively, wood protection. • Distances of base-structure for wall and ceiling Wall: max. 416 mm Ceiling: max. 333 mm. • Ceiling constructions are to be built pressure stiff, also see the chapter "Ceilings". Important notes • Changes of the length of the Rigidur boards due to the influence of temperature and humidity must be made up for by regularly aligned expansion joints at a distance of max. 10 m. • Condensation due to vapour diffusion is to be prevented. Calculatory proof for non existing condensation as per DIN 4108 is to be provided. Joint technique The Rigidur boards are to be installed with Rigidur Joint adhesive or Rigidur Nature Line Joint adhesive on the front sides, they must be filled or designed as open joint. In case of connections to other construction parts (e.g. concrete) the construction of the boards must be separated from the adjacent construction part. Final coating Before any final coating is done the Rigidur board is to be coated with a retardant primer. The board as well as the final coating e.g. paint or plaster, must have the manufacturer's approval for the respective purpose of use and must light-transmissive. 123 © by Rigips. 2. edition, April 2006 All statements in this brochure correspond to the latest state of development and were worked out for you at the best of our knowledge.
