Novia Gas Membranes

Novia supplies two gas barriers offering radon gas and methane gas protection, which also comply to EN 13967 as Damp Proof Membranes (DPM membranes): Novia® 1600 Gauge Radon Barrier & Novia® Methane Pro 390.

Each membrane, as it increases in protection level, will also protect against the level beneath. Methane barriers protect against damp, Radon, Carbon Dioxide, as well as the Methane gas they are installed to combat. Radon barrier will stop damp, Radon and Carbon Dioxide. Please check which material should be installed by trained professionals prior to installation.

Novia have worked to ensure that our Methane Pro 390 membrane is suitable for use with BS 8485 installations, as either a taped or welded installation. This membrane has been tested fully, including joints, to ISO 15105-1. Full details regarding this product can be found on the individual product page and datasheet. 

If installed as a taped system, Novia® 1600 Gauge Radon Barrier & Novia® Methane Pro 390 joints must be installed using the following Novia gas tight sealing tapes: Novia® Double Sided Butyl Tape (50mm minimum width) between laps and Novia® Single Sided Aluminium Foil Lap Tape (96mm minimum width) on overlaps.

Our gas and damp proof membranes are available for specification via NBS Source software.
