Polyethylene methane and radon gas barrier.
A tough, durable self-adhesive membrane specially developed to protect against the ingress of methane and radon gases and other ground gases and contaminants. This is achieved by using aluminium as the primary barrier and reinforcing and protecting this by laminating a tough, biaxially oriented HDPE film to one side and a robust bitumen rubber compound to the other. To facilitate easier lap seals, the membrane has a selvedge of bitumen rubber.
It is used to provide an effective barrier to water, water vapour, radon, methane and carbon dioxidein all forms of construction. When installed and applied correctly, it provides an effective barrier to ground gases in accordance with BS 8485 and provides Type A barrier protection in accordance with BS 8102 – Table 1 and provides levels of protection for grades 1, 2 and 3 in accordance with BS 8102 – Table 2. Under normal conditions of use, Triton TWS/EX 100 GM will provide an effective barrier to water, water vapour, radon, methane and carbon dioxide for the life of the building.
