Insulation Baffles Installation 4 Inch
Continue working upwards from the roof peak to the rafter Bay, overlapping the edges of each baffle with those below. If the baffles reach the soffit vents they can be sealed. Spray foam works well for this. Foam blocking might also be necessary: this can be stapled to larger spaces, and your baffles caulked where they reach the roof deck. Final, seal any seams in between the overlapping Baffles. Insulation can be placed on top of your baffles.
Rafter Baffles For Insulation: Rafter baffles are great for protecting your rafters and supporting insulation. There are many different types of baffles. Some are designed to fit under the floor while others are installed over joists. The SmartBaffle is one option that is both durable and easy to install. Its non-collapsing construction is made to prevent material from entering into areas where it is not needed. It also comes in different widths to accommodate different rafter widths.
