Potential for Condensation on Windows
New build in western Massachusetts (zone 5) – we are using Loewen double pane windows, with 6” wall cavity fluffy insulation and hi R (r13) exterior continuous foam. Other pertinent details: windows installed at exterior (wrb (typar?)) plane, ~r60 unvented roof, central ac/erv ducting, radiant floor heat. I am concerned by a few other similarly detailed local examples where cold temperature condensation issues have come up. Is there a way to ensure we won’t have the same problems? Do we need an engineer to look at all this and give a report?
