Protech GM Super gas membrane is a reinforced LDPE, loose-laid gas barrier that incorporates an aluminium foil layer to provide maximum protection from the ingress of methane, carbon dioxide and radon in new developments. Its unique composition makes the membrane extremely robust and flexible and, as a result, easy to install on site. It also provides protection from damp eliminating the need to install a separate DPM.

Fully compliant with the recommendations made in Ciria 665, BS8485 and The Local Authority Ground Gas Handbook when installed in accordance with BRE 414.
