RADBAR® Radon Gas Barrier


Radbar Radon Gas Barrier is a quality driven product widely used throughout the UK and Europe to protect against Cancer causing Radon Gases. The standard Radon membrane is produced at 300mu using only top grade material to ensure consistency and quality. Custom roll sizes are available (contact our sales team) but our established roll dimension of 4M x 25M is designed to be easy to install, while reducing the use of tape and sealants needed for jointing.

Manufactured from virgin grade polymer the material results in an extremely strong and durable membrane with superior elongation properties compared to reinforced products.  Where cost is critical, Radbar can be more economical than other certified products, ensuring a combination of quality and cost efficiency.

The distinct green and red rolls are all uniquely labelled and registered for complete traceability and can be used safe in the knowledge that the product has been independently tested, certified and carries BBA and ISO9001 approval.

When dealing with Radon gas BRE 211:2007 should always be consulted for guidance on identification, protective measures and installation requirements.
