OBEX CORTEX EPDM Membrane With Butyl is a fully flexible membrane used to create weather and airtight seals around openings such as windows, doors and curtain walling on non-relevant buildings.
The membrane is manufactured with pre-attached butyl strips which enable the membrane to be bonded directly onto the window frame.
The EPDM can be supplied with a single butyl strip to one edge (0751), or one strip to each edge on the same side (0752), or one strip to each edge on opposite sides (0753).
Refer to the TDS sheet for more information.
