Hello, I was thinking of doing the same thing for make up air at my place but was concerned about bringing in cold air into metal duct and getting condensation and possible mold growth eventually. Do you believe this is something to be concerned about in a cold climate?
Love the tip and the drawing!
I'm trying to get Lowe's in Waterford, MI to order some 2 inch comfort board for my exterior insulation. They will only order if I get half a semi load! I drove to Sarnia, ONT to get some from the Lowe's there, but its a 3 hour round trip with two border crossings involved. The more Fine Homebuilding illuminates Roxul Comfortboards benefits the sooner we may be able to get this product in the states. Its Perm ratings are great and allow your walls to dry to the outside, unlike foam board insulation. Call your local Lowe's and ask for it, maybe we can start a movement, like Alice's restaurant!
