A tri-polymer membrane which provides a highly effective barrier against radon, methane, carbon dioxide and hydrocarbons and VOC's. Complies with BS8485 and CIRIA C748.

Features and benefits:

Resistant to hydrocarbons and VOC's
Suitable for hot welding.
Very high puncture and tear resistance.
Compatible with vented systems.
Outstanding flexibility properties making it easy to install, especially when compared to HDPE films.
Superior mortar adhesion to prominent embossing to prevent slip planes when being used as DPC.
CE marked, Type A EN 13967:2012.
