I've a 50 year-outdated seasonal cottage in a very northern local climate. The easy 6/12 gable roof is made up of precise 2x6 rafters (24" oc), sheathed with one/two" plywood and lined with asphalt shingles.

I'm a homeowner in Seattle. Have got a freshly-framed, vented cathedral ceiling to insulate. Straight bays, 2x12, 24" o/c. The present plan is to utilize batts of some sort during the bays, acquire care to air seal the inside surface, keep away from penetrations, air seal the vent channel too (bays entirely sealed), double primary roofing company about us The within surface for vapor resistance. I have a pair questions about baffling the vent channel: 1. Many of the constructing pros I am Doing work with come to feel the jury is still out on baffles and therefore are recommending leaving the batts open up for the channel other than near the vents, assuming the 1-2" air channel is often maintained.
two. Install durable internet site-designed air flow baffles in each rafter bay before you spray the foam. That way you find yourself with a roofing company birmingham alabama vented cathedral ceiling.

Simply because It really is very clear to me doesn't suggest It can be distinct to Every person else.
