Been saying that for about 30 years. Was glad to see the CMHC "About Your House" brochure Attic Venting, Attic Moisture and Ice Dams in 1997-8 or so as it finally supported what I was saying to people since 1977-8 when I discovered the NRC Building Digests and CMHC's The Conservation of Energy in Housing.
