GPS Universal Gas Barrier is a monolithic hybrid virgin polymer manufactured using the blown extrusion method. The membrane contains no recycled material, as a result it is consistent and doesn’t include any bio-degradable content thus providing excellent results for gas permeation. The membrane is also suitable for use as a damp proof membrane. GPS Universal Gas Barrier prevents the transmission of harmful gases and due to the nature of its construction, the membrane overcomes problems associated with membranes manufactured from post-consumer recycled waste. GPS Universal Gas Barrier is suitable as a radon, carbon dioxide and methane barrier for NHBC Amber 1 situations and does not normally require third party verification (NHBC issue 20 – April 2016) For Amber 2 situations utilise GPS Total Gas Barrier. Third party verification would be required.
