System Components

Torch Flex Vapour Barrier

Vapour Control Layer (VCL)

Torch Flex Vapour Barrier is an SBS modified metal lined vapour control layer, for torch-on applications. A high-performance membrane that prevents water vapour from entering the waterproofing system, which can lead to the disruptive formation of condensation.

Torch Flex Ultra Vent

Underlayment

Torch Flex Ultra-Vent is a high-performance torch-on base sheet, utilising adhesive strips on the underside to allow for trapped vapour to disperse throughout the roof system; preventing membrane blistering and ensuring the longevity of the system.

StressPly Defender Plus

Mineral Cap Sheet

High-quality polyester reinforcement and blended SBS rubber compound for superior waterproofing protection. The integrated head-lap strengthens the bond between the rolls, for assured watertight protection.
