Rafter Baffles For Insulation
Insulation Baffles Cardboard: Cardboard insulation baffles help channel hot and cold air to roof vents. They also help prevent the insulation from blocking the soffit area. Cardboard attic baffles are made of corrugated stock that is folded or stapled to create a sturdy structure. However, they can be fragile and degrade over time.
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.
Rafter baffles for insulation: Rafter baffles are a great option to keep your insulation in its place. They create a gap between rafters to prevent air from getting out. They are available at a variety sizes and can be adjusted to fit various rafter widths. They can also be used for double coverage at the eaves.
