We are thrilled to announce that our Radbar Flexible Hydrocarbon Membrane and Radbar Hydrocarbon DPC are the first flexible hydrocarbon barriers to be certified by the BBA.

Radbar Flexible Hydrocarbon Membrane protects against Hydrocarbons, VOC’s, methane, carbon dioxide, radon and moisture. It also complies to BS 8485:2015 for use on CS3 and NHBC Amber 2 sites.

The membrane can be jointed using double and single sided tapes or by welding, as several installation companies have reported it “welds beautifully”.

Radbar Flexi Hydrocarbon membrane is supplied on rolls 1.3m wide and 20m long, the membrane is 1mm thick and extremely flexible, making detailing corners and penetrations easy.
