Are ventilation channels effective in creating a vented attic?
I have been reading the site for a year trying to figure out how to insulate my older 1 story home’s attic. There are a number of articles about insulation behind knee walls and the issues of creating an air barrier and getting enough insulation in. And then not defeating the fiberglass by wind washing. I haven’t seen any articles that discuss in roof venting low down. I have almost zero soffit vents and poor flow patterns should soffit vents be installed. My new roof goes on in a few weeks, and the plan is a ridge vents and inflow on the roof low down. Then I expected to insulate the floor and top off the fiberglass with a thin layer of rigid insulation to prevent wind-washing. Do I still need baffles? There are no duct works or HVAC in the attic.
I can crawl pretty deep into the space between the floor of the attic and the exterior wall but it’s no picnic.
Thanks for the advice,
