OBEX CORTEX 0221FR Class A2-s1,d0 Breather Membrane features water resistant yet breathable technology, which facilitates the escape of moisture and the prevention of condensation within the external wall construction. It can be applied to many surfaces including sheathing board, concrete and insulation.  

OBEX CORTEX 0221FR is a black membrane, so makes for an excellent backdrop behind perforated or open jointed cladding.

The membrane is installed using the OBEX CORTEX 0825 Installation Kit which includes 2 rolls of 0824FR double-sided tape and 6 rolls of single sided 0823FR UV façade tape.
