Product Description

OBEX CORTEX EPDM Membrane is a flexible membrane which is used to create water and airtight seals around openings such as windows, doors and SFS sections on construction projects. Cortex EPDM has excellent water resistance properties and is BBA approved for façade applications.

The use of CORTEX EPDM is limited under the England and Wales building regulations. Refer to the OBEX Technical team for further details.

Typical uses include;

Weather & airtight seals around windows, doors and curtain walling systems
Weather & airtight seals from SFS sections to the concrete frame
Top of parapet walls
Balcony waterproofing
