[Greenbuilding] Insulated overhangs

[Alan Abrams]

 I’ve made it a practice in the pnw to air seal and insulate overhangs –
> especially large overhangs or porches. It seems like a waste but too much
> moisture and potential for condensation = mildewy soffits. Builder neglected
> to do this on a project and now the wood soffits are getting saturated and
> staining. I am looking for a solution to recommend to the client short of
> removing all the soffit material. I am considering removal of a few soffit
> boards to allow for foamed insulation but don’t have personal experience
> with how effective it could be to form an air barrier or how well it can be
> done to fill the area. The soffit wood is natural t&g so cannot reliably be
> sealed on the exterior.
