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. The membrane also provides protection from damp eliminating the need to install a separate DPM.
