Description

Sigma 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 biodegradable content thus providing excellent results for gas permeation. The membrane is also suitable for use as a damp proof membrane. Sigma 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.

Sigma 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 Sigma GPS Total Gas Barrier. Third party verification would be required.
