The 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 cod. In addition, the fire resistance requirement for external walls is determined by the distance of the wall from any relevant boundary. Where any part of the external wall is less than 1 meter from any point on a relevant boundary, the designer must consider fire exposure from each side of the wall separately; where the external walls is 1 meter or more from any 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 240 minutes to external wall of portal framed light industrial units.
