Novia® Methane Pro 390 Gas Barrier - Methane gas barrier
Verified by manufacturer 3 months ago
Foil laminated and reinforced polythene methane gas barrier and damp proof membrane.
Application
For use as a methane and CO2 gas barrier, exceeds the requirements of BS 8485:2015 groundwork applications. Material has 390 GSM weight and ≥0.4 mm thickness. Suitable for use in BRE report BR 211-2015 radon applications.
Description
A premium specification multi-layer laminate damp proof membrane (DPM) incorporating reinforcement and an aluminium foil core. Novia Methane Pro 390 is approved for Methane gas applications and exceeds the requirements set out in British Standard BS8485 and can be used in radon gas applications or as a high performance damp proof membrane. Novia® Methane Pro 390 carries UKCA approval.
All Novia® Methane Pro 390 membrane joints and perimeter edges must be correctly taped and sealed using the two tape sealing system (50 mm double sided butyl tape and 96 mm aluminium foil tape) to ensure a fully compliant gas tight seal or this product is also suitable for welded installations. The membrane is not suitable for applications where hydrostatic pressure is present i.e. building in to a blockwork or brickwork wall.
