Supalux® P R E F A C E FIRE RESISTANCE OF STRUCTURES Fire resistance is not a property of a material but the performance of a complete element of structure which will generally be composed of a number of different materials and components. The fire resistance of loadbearing and non-loadbearing partitions and ceilings are determined by a test in accordance with the criteria of BS476: Parts 21 and 22: 1987 respectively. Specifications shown in this document have been tested or assessed by independent authorities for compliance with International Standards. Additional testing has been carried out worldwide. A fire resisting construction can be any one of a number of elements in a building for example a wall, ceiling, duct, protected shaft or cavity barrier. This document gives details of some of the constructions used in fire resisting applications. For full details on many other fire resisting applications please refer to Intumex Asia Pacific. NON-COMBUSTIBLE MATERIALS Building materials are classified as noncombustible when they are tested to BS476: Part 4: 1970 or BS476: Part 11: 1982. Supaluxfi is non-combustible. These tests provide a measure of the propensity of materials to generate heat and flames under standardised heat exposure conditions, and represent the highest and most stringent standard for the fire performance of materials. FIRE TESTS Fire resistance is determined in tests which subject a representative specimen to heating conditions based on a standard temperature/time curve while subject to its design loading. Test methods are contained in the various parts of British Standard 476. The fire resistance of a specimen is the time in minutes for which it continues to meet the criteria for Stability, Integrity and Insulation. Standard temperature/time curve (BS476: Part 20: 1987) The specimen under test is progressively heated in an accurately controlled furnace, the temperature of which varies with time as closely as possible to an International Standard. This is set out in graph form and is called the time-temperature curve. The heat evolved is not necessarily that which is produced in a true fire situation but is an agreed standard for purposes of comparison. After 30 minutes the temperature of the furnace is 841OC, increasing to 945OC after 60 minutes. Then to 1049OC after 120 minutes to a maximum 1213OC after 360 minutes. These figures illustrate how stringent these performance tests are in respect of elements of structure. The fire resistance of an element is the time in minutes from the start of the test until failure occurs under any one of the criteria of Stability, Integrity and Insulation if all are appropriate to the particular type of element being tested; or, if no failure occurs, until the test is terminated. For example, a test result showing: Stability: 120 Integrity: 120 Insulation: 15 would mean that a specimen failed in respect of Insulation after 15 minutes, but complied with the other criteria for at least 120 minutes. A large number of various types of elements of structure have been tested over a period of years. The designer of a building can therefore refer quite readily to previous test results from a range of official publications and will know whether or not the particular type of construction selected will be appropriate in respect of the fire resistance of the proposed elements of structure. Should he wish to use new or untested materials, testing would be necessary and a satisfactory report would need to be furnished prior to approval being given for the use of such elements in the construction of a particular building. Stability is the ability of the specimen tested to withstand deformation or collapse. Integrity is the ability to withstand cracking or opening up to the extent of allowing flames to pass through. Insulation is the ability of the face of the element not exposed to heat to remain comparatively cool. Supalux® I N T R O D U C T I O N S upalux® consists of calcium silicate matrix reinforced with selected fibres and special fillers. It does not contain asbestos or other inorganic fibres. The board is semicompressed and cured in high-pressure steam autoclave, thus providing high dimensional and chemical stability with low alkalinity. Supalux® calcium silicate board is off-white in colour with a sanded fair surface and lightly textured on reverse. DIMENSIONAL STABILITY Supalux® has extremely good dimensional stability even when used in humid environment, or conditions with changing temperatures. FIRE PERFORMANCE Supalux® is non-combustible to BS 476: Part 4: 1970. It has Class 1 Surface spread of flame to BS 476: Part: 1971 and Class O surfaces as defined in the Building Regulations. It contains no soluble ingredients and its fire performance is not degraded by age. Supalux® does not generate smoke or toxic gases during fire. DURABILITY When left undecorated, the board will not degrade, rot or deteriorate physically. EFFECT OF MOISTURE ® Supalux is tolerant to moisture. It will absorb water causing some strength lost, which is fully recovered upon drying. Moisture has no permanent effect, nor cause leaching or efflorescence from the board. THERMAL Supalux® experiences very low movement in relation to temperature change. It provides some degree of thermal insulation; and is an ideal support for thermal insulation material. BIOLOGICAL Resistant to attack by insects or vermin, and does not nourish mould growth. CHEMICAL is not Supalux® affected by brine and dilute chlorine solutions. It is resistant to low concentration of most acids, alkalis, bleaching agents and solvents. EASE OF USE Supalux® is lightweight and it can be cut or drilled using conventional woodworking tools. The board has low alkalinity; and is compatible with all common building materials. It is ready to accept most decorative finishes, without any anti-alkaline primer.

INDUSTRIAL LINING T he fire resistance requirements for external walls depend on the type and size of the building. The minimum periods of fire resistance for the elements of structure in an industrial building can be found in the local building code of practice. In addition, the fire resistance requirement for external walls is determined by the distance of the wall from the relevant boundary. Where any part of the external wall is less than 1m from any point on the relevant boundary, the designer must consider fire exposure from each side of the wall separately; where the external walls is 1m or more from the relevant boundary fire exposure is only considered from inside the building. Supalux® Industrial Lining is a strong, fire rated exposed or conceal grid system designed to provide fire resistance of up to four hours to external wall of industrial factories. 4-hour Fire Rated Supalux® Industrial Lining M 0.6mm thick profile steel cladding N 125mm x 50mm x 3mm thick channel sheeting rail at 2200mm centres O 25mm x 25mm x 0.4mm thick steel angle fixed to channels using one number No.8 self-tapping screw per leg P 25mm x 50mm x 25mm x 0.4mm thick steel channel at 610mm centres Q 9mm thick Supalux® cover strip 75mm wide R 25mm x 25mm x 0.91mm thick top and bottom angle S 9mm thick Supalux® fixed to channels and cover strips using 19mm long No.8 self-tapping at 300mm centres NOTE: For fire resistance where insulation in excess of 15 minutes is required for this application, please consult Intumex Asia Pacific.
