The BBA certification

From one of the UK’s most highly regarded construction industry approval bodies. Thanks to the quality of Obex’s Cortex EPDM Membrane System, the BBA has certified the entire EPDM System for:

Weathertightness – the system will resist the passage of wind-driven rain, snow, run-off water and dust into the interior of the building

Air barrier continuity – the system will contribute to maintaining air barrier continuity at lintels, jambs and sills

Resistance to damage – the system is suitably robust so as not to be damaged during installation

Durability – the system will continue to function for the lifetime of the frame around which it is installed

Test carried out by the BBA indicates the system will continue to function for the lifetime of the frame around which they are installed. The BBA has put all parts of the Cortex EPDM Membrane System through vigorous tests, carrying out on-site evaluations, inspections of production and checked compliance with relevant building regulations.

At Obex we are proud to say we are the only company that has this prestigious certificate to give you peace of mind and reassurance that you are in the best hands when purchasing the CORTEX EPDM Membrane system from Obex.
