[Greenbuilding] Insulated overhangs

[JOHN SALMEN]

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.

 

Any thoughts or recommendations?

 

Thanks

John
