Conditioning time and temperature (minimum): As recommended by manufacturer with time extended by a factor of two for materials stored or transported at a temperature of less than 10 C immediately prior to laying. 350 ENVIRONMENT Temperature and humidity: Before, during and after laying, maintain approximately at levels which will prevail after building is occupied. Ventilation: Before during and after laying, maintain adequate provision. 350A ENVIRONMENT HEAT Areas where open cooking or open flame equipment is being used should comply with the following: - Altro Whiterock panels once installed should not be exposed to temperatures above 60 C. - Before the testing of Kitchen equipment which is likely to espel severe heat, extraction systems must be operational. Failure to do so may result in expansion problems. - With the construction of a dry wall system in a kitchen area or where the area has been adapted to form a wall behind cooking ranges, Altro Walls recommends the substrate or dry wall lining should be constructed with a Calcium Silica board. Stainless steel panels should then be used to clad these areas. - Hot pipes and steam pipes should be insulated and a 3-5mm expansion gap should be created when installing panels around these pipes.
