NHBC Traffic Light classification
The NHBC’s ’Traffic light’ guidance on the classification of risk from ground gases has been widely adopted in the housing industry. This membrane conforms to all current requirements and because of its distinct orange colour makes it easily identifiable and is uniquely labelled for traceability. The membrane is 2000 gauge allowing it to stand up to the rigours of the build process, using the ancillaries available with this system a buildable and cost effective system is available. It is recommended the installation is independently verified to conform to NHBC and planning requirements.
