DCT-W41-3

EXTERNALLY INSULATED CLT RAINSCREEN (PIR)

CLT mass timber wall made water and air tight by the self-adhered vapour permeable ProctorPassive Wraptite SA, externally insulated with a rigid thermoset DCT PIR insulation board and protected by a rainscreen cladding supported by the Nvelope engineered helping hand sub-framing system. As the PIR and CLT are both deemed combustible, this solution is never recommended for type A or B non-combustible wall construction.
