[Greenbuilding] ***SPAM*** Re: ***SPAM*** Wet-spray insulation

[Lynelle Hamilton]

Mike,

I'd assume that the gable is sealed (foam) at the outer side. Did you 
also use a vapour barrier on the warm side of the batts?  How did you 
calculate the condensation point? Do you have any problems with moisture?

Thanks!

Lynelle

We blew high-density foam on the under side of the roofing plywood, then added R-38 batts between the rafters. The other roof has a flat ceiling under it, with R-49 blown-in cellulose (not damp spray). Our general was Dave Heslam, who now works at Earth Advantage in Portland, his crew did the insulation. Hope that helps.
