Insulation Baffles Installation Tips
Bob Vila explained that attics contain intake vents underneath the roof's eaves which allow in cool air while hot-air exhaust vents at peak of the roof let out heat. The intake vents can either be one continuous perforated part or spaced out in a series of vents. For gable roofs the vents could be placed on the side or near the peak of a gable.
Before installing insulation baffles, remove old insulation from the edges of the attic. Then, place a baffle in each bay between rafters. Make sure that each baffle is positioned snugly, and that the bottoms are level with the ceiling joists. After securing the baffles, use a spray foam to fill any gaps and seal the connections. This will prevent air leaks. Insulation baffles are a great way to keep the attic and crawlspace warm. They're designed to resist moisture and deterioration in harsh conditions. They can also reduce energy bills and improve the air quality of your home.
We go above and beyond the installation of a baffle. We also install a blocking material and seal the seam at the exterior top plates seam. This offers our customers many benefits. Our experienced crew installs closed cell spray insulation at the exterior of the top plate, right up to and including the baffle. See sketch below. This premium process is in addition to our standard benefits:
