OBEX CORTEX 0520FR W1
OBEX Cortex 0520FR is a Class B breather membrane for external wall construction.
OBEX Cortex 0520FR is water resistant and vapour permeable, allowing moisture to escape from the wall build-up while helping reduce the risk of condensation within the structure. Its W1 watertightness rating to EN 13859-2 makes it suitable for applications where reliable weather protection is required, with up to 6 months’ UV exposure during construction.
- W1 watertightness to EN 13859‑2 for reliable water resistance
- supports moisture control and condensation reduction
- Suitable for sheathing board, concrete, and insulation
- Up to 6 months UV exposure during construction
- Excellent tensile strength and tear resistance for durable handling
- Third-party certified for performance and reliability
OBEX Cortex 0520FR provides breathable protection within external wall systems.
It allows moisture vapour to pass through the wall build-up while protecting against external water exposure. This helps manage moisture within the construction and supports the performance of insulation within the wall system.
The membrane is suitable for use on sheathing board, concrete and insulation, giving flexibility across a range of external wall applications.
