- A dense pattern of micro-perforations enables FIRESARK BREATHER to achieve Class 3 vapour permeable classification
- Ideal secondary physical barrier offering a second shield to ember attack
- Advanced thermal performance, reflects up to 97% radiant heat flow improving the thermal comfort
- Suitable for use in all BALs Zones: BAL-LOW, BAL-12.5, BAL-19, BAL-40 & Flame Zone BAL-FZ
FIRESARK BREATHER is an Extra Heavy Duty, Class 3 vapour permeable membrane designed to reduce the risk of interstitial condensation in building systems while offering superior fire performance to exceed the requirements of the National Construction Code.
A dense pattern of micro-perforations allows water vapour to escape from the wall structure while restricting the ingress of liquid water. FIRESARK BREATHER is intended for use in double brick and brick veneer wall systems in climate zones 6, 7 and 8.
