Torch Flex Ultra-Vent

Description

High performance polyester reinforced, rubber modified roofing underlay designed to be used in torching applications. It includes adhesive strips on the underside, which allow trapped vapour to disperse throughout the roofing system. The unique adhesive qualities of the thermoplastic bitumen strips ensure that the bonding quality equals that of a traditional roofing system using conventional venting underlays.

It can be used in conjunction with Torch Flex Ultra Bond vapour barrier and StressPly® membranes to create a roof system with a low installation cost which doesn't compromise on the quality and life expectancy of the completed system.
