Bradford Roof Valve & Roof Valve BAL Roof Ventilator

 

Bradford Roof Valve is a low-profile, static roof ventilator (no turbine) that quietly releases air from the roof space without using electricity. It's ideal above ceiling or exhaust fans, making it a simple way to remove air from bathrooms, kitchens and laundries through the roof.

For homes in bushfire-prone areas, Roof Valve BAL offers the same neat look with added bushfire confidence. When installed to specification, it is suitable for BAL 12.5-40, providing a compliant outlet for 150 mm ducted exhaust in wet areas while maintaining always-on ventilation. Australian made and tested, and supported by CSR Bradford technical advice and warranty.

Features and Benefits

 

Bradford Roof Valve products help control heat and moisture in the roof space so ceiling insulation works better and the risk of condensation, mould and musty odours is reduced. Because they're passive, there are no running costs or wiring, and the low-profile ASA plastic head sits neatly near the ridge on metal or tiled roofs.
