We caught a consumer in the hardware store and he was asking about the leaking roof on his new addition in the Beaches area of Toronto. Often in that area, a back porch is converted into living space with what we call a "compact roof" -- a roof/ceiling assembly that is about one foot thick with i...

Fiberglass batts, mineral wool batts and all kinds of rigid foam boards are commonly used to insulate basements both inside and outside.
One of the critical rules when insulating basements on the inside is that there must be no air space between the insulation and the wall. (see no air space beh...
