DCT-W20-2

LIGHTWEIGHT THERMALLY BROKEN STEEL FRAME WALL (PIR INTERNAL INSULATION)

A lightweight clad steel frame wall insulated within the frame with a continuous closed cell high compressive strength DCTech XPS thermal break strip fixed between the cladding and the frame to form a drained and vented cavity. The frame and insulation are protected by a vapour permeable, air and water tight ProctorWrap sarking. The interior DCT PIR Silver insulation is mechanically fixed directly to the interior face of the frame and must be taped and sealed to form a continuous air and vapour control layer. As the thermal break strip and PIR insulation are both deemed combustible, this solution is never recommended for type A or B non-combustible wall construction.
