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.

“We’ve moved over from plain EPDM membrane and paste adhesive to Cortex 0751 EPDM with butyl strip and 0801 termination bar. Not only has this saved us a huge amount of time on site, but also ensures a clean application and accurate linear meterage of material estimated and ordered. We would fully recommend this method to other users as we have proved a significant time and cost saving. - Sean Heywood - North Chesire Windows”
