DCT-W21-1

LIGHTWEIGHT THERMALLY BROKEN STEEL FRAME WALL (VULCANWOOL)

A lightweight clad steel frame wall insulated by non-combustible DCT Vulcanwool and a continuous Vulcanwool high compressive strength 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 SmartVap intelligent air barrier membrane installed to the inside face of the frame must be taped and sealed to form a continuous air and vapour control layer and is best fixed behind a batten to forms a service cavity behind the plasterboard. As the VulcanWool insulation and thermal break strip and both deemed non-combustible, this solution is suitable for type A or B non-combustible wall construction.

New call-to-action

ProctorPassive RS-IT

ProctorPassive Rainscreen (RS-IT) is a vapour permeable wall wrap for use in closed and open joint rain screen installations in vertical wall constructions behind ventilated facades with regularly spaced open joints no greater than 50mm wide accounting for 30% open total surface area offering a combination of UV durability and high water holdout without compromising vapour permeability.

DCT Vulcanwool Non-Combustible Thermal Break Strips are used to reduce the thermal bridging between external and the internal building fabric.

ProctorPassive SmartVap is a light duty air barrier and variable vapour diffusion vapour control membrane.
