Gas Protection Membranes

GPS 2000
GPS 2000

Application: GPS 2000 (Rn)(CO²)(CH4)
Radon is a naturally occurring radioactive gas formed by the breakdown of uranium and radium.
Carbon Dioxide is a colourless, odourless gas formed as a by-product of decomposing organic matter.
Methane is a colourless, odourless, flammable gas formed as a by-product of organic material breakdown.

A low permeability, highly robust, monolithic, thermoplastic LDPE membrane for use as a radon, carbon dioxide and methane barrier for NHBC Amber 1 situations.

GPS 2000 prevents the transmission of harmful gases. Due to the nature of its construction; the membrane overcomes problems associated with membranes manufactured from post-consumer recycled waste.

GPS 2000 fully complies with the recommendations of the Building Research Establishment Document: 414 and with the requirements NHBC Guidance on methane and carbon dioxide report issue 20 for Amber 1 sites.

GPS 2000 also acts as a damp proof membrane and can be heat welded.

Available in a standard roll size of 4 x 12.5m


The performance of gas membranes is heavily dependent on the quality and design of the installation, resistance to damage after installation and the integrity of the joints (BS 8485)
