Z Grill Insulation Blanket
Depending upon the space available for venting, you might need several baffles. For example, if your attic measures 150 feet in size, you will need one for every square foot of rafter vent. Before you install, you should consult an experienced professional. For a house to remain cool in the winter and warm during the summer, it is important that it has the correct ventilation. Proper ventilation is essential to keep your house cool in winter and warm in summer. The humidity from the attic can cause damage to structural components and wood. It can also lead to ice dams. Installing baffles is a good way to ensure that condensation doesn't form on your roof.
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.
Continue up the rafter to the roof peak, covering each baffle's edges. Seal the baffles that extend to the soffit vents. Spray foam can be used to seal the baffles. Foam blocking is also possible. This can be stapled on to fill larger spaces. The seams that run between the baffles should be caulked. Insulation can also be installed on top of your baffles.
