OBEX CORTEX 0500FR Class B Interface Sealing Membrane With Gasket is a fire classified EPDM-alternative membrane which is used to create weather and airtight seals around openings such as windows, doors and curtain walling on construction projects.
This membrane achieves a fire classification of Class B-s3,d0 when tested according to EN 13501-1 and is also fully BBA approved for façade applications.
This membrane is manufactured with a gasket on one edge which enables the membrane to be securely attached directly into the channel of the window frame, or into the OBEX CORTEX Gasket Carrier.
Our range of gaskets are suitable for most widely used window systems such as Schuco, Reynaers, Aluprof, Senior and many others.
