VELOX SPECIFICATION Product description The ʺVELOXʺ single‐pane dividing partition is principally composed of an outer structure made up of 2 extruded aluminium profiles and glazed panels, with a total thickness of 46.6 mm. The main framework is made up of a 50‐
mm high base (primary) profile to which a second (closing) profile is hooked on and fastened, integrating completely in terms of both size and shape. The patented hinged attachment system allows easy and immediate opening and closing of the profile and thus easy and hidden attachment of the partition profiles to the building structure with screws or expansion fastenings. The particular structure of the base (primary) profile accommodates different glass and panel thicknesses (up to 18 mm), as well as adjustment feet, glass holding brackets which both lock the glass to the structure and hook onto the external closing profile. It also accommodates pivilene trim to eliminate sound bridges with floors and ceilings as well as seals for the glass, alignment and assembly brackets, and mounting hardware. The open‐profile mounting system allows the glazed panels to be mounted flush to the base profile, allowing any height differences to be made up. ( +/‐ 15 mm). The glazed panels used are self‐supporting, 10 mm thick for heights of up to 3 m and 12 mm above this up to 3.80 m. They are levelled by adjustment feet and attached to the structure with brackets screwed directly to the profile structure. Screw holes are made during the extrusion process, so there is no need to drill them. All panels are made of safety glass, either laminated with 0.38 or 0.75 mm PVB film placed between the plates, or else tempered, that is treated with a toughening process which gives them increased strength (up to five times greater than normal glass). The glass can be personalised using different technologies which give them different optical and aesthetic characteristics: ‐ by the addition of colouring to the molten glass. This colours it but nevertheless leaves it transparent. ‐ by treating its exterior, making the treated surfaces opaque. Treatments include acid etching, grinding and digital screen printing. ‐ by painting and/or the application of coloured or printed films to the interior or exterior of the glazed panels. ‐ by inserting various materials inside the extra‐clear glass sheets, such as veneers, fabrics, silks, papers, fine mesh, marble, photographs, leaves etc. This is performed by a special lamination process using EVASAFE film (ethylene‐
vinyl acetate). The VELOX profiles also accommodate blind panels made of HPL (High Pressure Laminate), which are stratified panels of overall thickness of between 10 ‐ 12 mm, made up of layers of Kraft paper impregnated with thermosetting resin. The outer sheets are decorated, with a vast range of colours and finishes available. Once the panels are formed they are heated under high pressure in special presses (9 MPa at 150°C) where condensation polymerisation of the resins occurs. This product has excellent shock resistance and is impermeable to water and fumes. It has good resistance to acids, and is hygienic and easily cleaned. It is not highly fire resistant, and in case of combustion can give off small quantities of formaldehyde, gas and smoke. Its density is 1.4 kg / dm3. Vertical joints between glass and glass and HPL panels are obtained using a special anti‐UV treated polycarbonate profile which does not affect the transparency and continuity of the glass area. It is also possible to use an extruded aluminium profile with the same section, or else to glue the glass together with a very thin film of transparent bioadhesive. Right‐angled polycarbonate connections and joints between multiple (3 or 4) partitions are performed similarly, with the same polycarbonate profile redesigned for the specific joint required, while in the case of aluminium connections, variable‐angle aluminium profiles with the same thickness as the glass are used. Connections with fixed walls and other types of partitions are made with telescoping aluminium profiles. NITOR single‐pane partitions can be integrated with dual‐faced elements (finished both on the front and back). The glazed panels are fitted in the sides and top of the covering creating an original alternation of full and empty, of transparency and volume. The depth of the unit can be distributed both symmetrically and asymmetrically, without compromising the internal capacity. Access to various areas is through door panels in 10/12 mm smooth‐ground tempered glass, either sliding or hinged. In situations with limited height available (up to 2700 mm) it is also possible to use hinged glass doors without frames (jambs). These are directly attached to the fixed lateral glass with special hinges. The doors can also be blind, 40 mm laminated or veneered units, or else glass with an aluminium frame. All doors are fitted with two aluminium hinges, but for heights greater than 2100 mm a third, central hinge can be fitted giving greater stability to the door panel. Hinged doors have an aluminium frame (jamb), which is also formed of a base profile and two other profiles which hook onto the first, allowing glass to be mounted flush to the doors as well. These profiles have hollows along their length to accommodate the seals for the glass as well as for the door. The doors can be fitted with different types of hinges and various types of handles and knobs, all with or without locks. The sliding doors run on ball‐bearing rollers and can be realised both with pulley systems, attached to the door frame and the side glazed panels, and with load‐bearing sliding guides fixed to the ceiling or the surrounding structure, this having a cover with the same dimensions as the surrounding profile to hide the sliding mechanism. An aluminium cable module is available for electrical wiring needs. This can be fitted to any of the systemʹs structural components. It can be mounted both vertically and horizontally and can contain electrical devices and controls, touch switches, speakers, plates and personalised markings. It is also possible to use a special module composed of a 210 x190 mm aluminium box, which is fitted in an area cut out from the glass abutting the door frame. This allows quick and functional installation of switches or electrical sockets (up to three), which can be connected via a cable run inside the door jamb to the floor and/or ceiling. The partitions can also be made free standing, using a self‐supporting system composed of an aluminium reinforcing boom and hidden zinc‐plated steel straight/angled joint profiles above and fixed to the upper profile of the partition. All this goes to make up a light, solid and easily assembled framework, perfectly adapted to join the partitions together and keep them completely stable. The free‐standing solution makes space planning easy with high or false ceilings, or when working in historic or listed buildings or making changes to the building layout. All aluminium profiles and parts can be supplied in the natural oxidised colour (brushed finish), but also in shiny aluminium finish (stainless‐steel/titanium type), brilliant aluminium finish (chrome type) or else coated with epoxy powder in RAL colours. The soundproofing abilities according to glass thickness and PVB thickness are as follows: 1.
5+5 glass with 0.38 mm PVB film = 33 dB 2.
5+5 glass with 0.75 mm PVB film = 35 dB (as standard) 3.
6+6 glass with 0.38 mm PVB film = 37 dB 4.
6+6 glass with 0.75 mm PVB film = 38 dB (as standard) 5.
Silence glass 5+5 Rw = 39 dB 6. Silence glass 6+6 Rw = 40 dB Certifying authority CISQ /ICILA
