Dealing with a SIP roof: A building project in northern Vermont will include a structural insulated panel (SIP) roof, but sealing potential air leaks may be difficult.


That's the problem facing Jay Hersh, who is about to build a house in northern Vermont that includes a SIP roof. In a Q&A post at GreenBuildingAdvisor, Hersh asks for advice on how to prevent moisture-laden air from migrating into the roof through seams between panels. And, he adds, what's the best way of preventing leaks from above?

The discussion is the subject of this Q&A Spotlight.

What concerns Hersh is that moisture finding its way into roof via seams between panels will condense on the outer layer of oriented strand board and lead to decay. His situation is complicated by a tongue-and-groove ceiling that will make it more difficult to foam and tape the seams from below.

Suggestions include specific membranes that will form an effective air barrier and special tape that can be used to seal seams. Oh, and one more suggestion: give up the idea of SIPs altogether and look for something less expensive and with better green credentials.
