To vent or not to vent, that is the question
O.K., I don’t want to be controversial, but in lieu of a recent high priced truss bid, I am thinking of constructing a roof with TJI rafters and am thinking of not venting it. The ceiling will of course be cathedral, the joist rafters will be 16″ tall, and I had planned on using plastic accuvent baffles continuos up the roof to create the venting channel, dense pack cellulose below. I do plan on a vapor barrier, ADA approach, or at least very fastidious air sealing…..Any thoughts, please share.
