DCT-W41-4
EXTERNALLY INSULATED CLT WITH RAINSCREEN CLADDING (NOT FIRE PROTECTED)
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 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.

DCT VulcanWool is a non-combustible high density mineral rock fibre stonewool insulation for use as external grade insulation with water shedding characteristics, designed for use in ventilated rainscreen facades and other thermal and acoustic wall, roof, floor and ceiling applications in residential and commercial buildings.
Nvelope Rainscreen Back Framing simplifies the complexity of modern building facades using a unique ‘helping hand’ bracketing system which is fixed to the substrate at set vertical and horizontal separations. Suitable for the most demanding facade materials, our range of Nvelope brackets, rails and rainscreen support systems are safe, economic and effective.
ProctorPassive Wraptite Self Adhesive (SA) is a light duty vapour permeable membrane for wall and metal roof application functioning as water and air barrier in one innovative vapour permeable self-adhering product.
