Insulation Baffles Installation Zoominfo
Continue working up the rafter bay to the roof peak, overlapping each baffle's edges with the next one. You can seal the baffles if they extend down to the soffit vents. Do this with spray foam. You may also need foam blocking: you can staple this on to fill larger spaces and caulk your baffles where they bump up to the roof deck. Finally, caulk the seams that are between the overlapping baffles. You can install insulation on top of your baffles.
After the insulation has dried, you can now place the batts, blankets, or blow insulation right to the edge. Note: In order to prevent insulation being blown into the attic floor, blow insulation may require additional blocks. This is done very well by placing a piece if rigid foam board on the outer edges of the top plates.
Be sure to remove any insulation that is leaking from the attic walls before installing insulation baffles. Install a baffle into each bay between the rafters. Each baffle should be placed in a tight position and the bottoms should touch the ceiling. After attaching the baffles to the ceiling, spray foam should be applied to fill any holes and seal the connections. This will prevent air leakage. Insulation baffles will keep your crawlspace and attic warmer. They can resist moisture and deterioration even in extreme conditions. They can also help lower your energy bills and improve your home's indoor air quality.
