Juta GP1

JUTA GP^®1 Gas Barrier is a multi-layer, low-density polyethylene membrane, reinforced with a polypropylene reinforcing grid with an integral aluminium foil. GP^®1 is specifically designed and manufactured to perform as a Methane, Carbon Dioxide, Radon, Ground Gas, VOC, air & Moisture protection system.

Juta GP^®1 should be used on any site where carbon dioxide, methane or radon is present up to and including CIRIA 665 SITUATION 6. The barrier is sufficiently resistant to the ingress of harmful gases into a building. On more heavily contaminated sites a passive or active venting system may be required to dilute the gases down to acceptable levels and specific design advice should be sought.

• High quality reinforced membranes.
• Low permeability to hydrocarbon and VOC vapours, carbon dioxide, methane and radon.
• Complies with latest codes of practice as published by the BRE and CIRIA, BS 8485
• Independently tested by third party UKAS accredited bodies.
• BBA approved and CE marked.
