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 Flex Plus

Mineral Cap Sheet

The torch-on cap sheet membrane contains a high-quality SBS rubber compound, for maximum durability, available in both charcoal and brown slate finishes.
