Application

Suitable for restricting the ingress of radon, methane and carbon dioxide into buildings from landfill and naturally occurring sources.

Description

JUTA GP®1 Gas Barrier is a multi-layer, low-density polyethylene membrane, reinforced with a polypropylene grid with 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.


Features and benefits:



  • High quality reinforced membrane.
  • 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, and BS 8485.


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.
