The BBA certification

We are the only company in the UK whose Membrane Systems are BBA approved, from one of the UK’s most highly regarded construction industry approval bodies. Thanks to the quality of the Obex Protection Cortex Fire Rated Sealing System and Cortex EPDM Membrane System, the BBA has certified the entire Membrane 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

Tests carried out by the BBA indicate the system will continue to function for the lifetime of the frame around which they are installed. The BBA put all parts of the Cortex Fire Rated Sealing System and Cortex EPDM Membrane System through vigorous tests, onsite evaluations, inspections of production and compliance with relevant building regulations.

At Obex Protection, we are proud to say that we are the only company which has this prestigious certificate, to give you peace of mind and reassurance that you are in the best hands when purchasing a product from the Cortex Fire Rated Sealing System and Cortex EPDM Membrane System.
