A Cross Laminated Timber (CLT) wall system manufactured by XLAM Australia and NeXTimber® is made airtight and watertight using a self-adhered Class 4 vapour-permeable ProctorPassive Wraptite SA, externally insulated with a non-combustible VulcanWool stonewool insulation, and protected by a rainscreen cladding supported by the Nvelope engineered helping hand sub-framing system. This configuration forms a continuous external insulation layer with minimal thermal bridging, while providing fire protection, thermal performance, and acoustic benefits.

Timber framed brick veneer wall, insulated within the frame and internally with DCT PIR Silver, protected by vapour permeable, air & water tight ProctorWrap sarking fixed to the outside of the frame.

A lightweight clad steel frame wall insulated by noncombustible DCT VulcanWool and a continuous 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 ProctorPassive 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.

Mass timber CLT made water and air tight by the self-adhered vapour permeable ProctorPassive Wraptite SA, externally insulated with a non-combustible DCT VulcanWool stonewool insulation, protected by a brick veneer cladding. The insulation is mechanically fixed with minimal thermal bridging, to form a continuous external insulation layer. As the CLT is not classified as fire protected timber this solution is not suitable for type A or B non-combustible wall construction.

CLT mass timber wall made water, air, and vapour tight by the ProctorGeo Vap 120 air and vapour retarder, externally insulated with a non-combustible DCT VulcanWool stonewool insulation, protected by a rainscreen cladding supported by the Nvelope engineered helping hand sub-framing system. The insulation is mechanically fixed with minimal thermal bridging, to form a continuous external insulation layer. As the CLT is not classified as fire protected timber this solution is not suitable for type A or B non-combustible wall construction.
