Description
BRANZ research has provided reassuring results for those wanting to add passive ventilation in roof cavities to counter condensation. Corrosion of metal fixings inside the roof space remains low, even in extreme marine environments.
Over the years, BRANZ has released many publications on passive roof space ventilation, and the topic is still attracting a lot of interest from the industry.
BRANZ Bulletin 630 Roof space ventilation is a good place to start when seeking to understand the intricacies of providing a well-vented roof cavity.
