Rafter vents also called baffles, are fittings that you add to the attic to ensure you completely cover your attic floor with insulation. Complete coverage is essential to ensure that you get quality coverage and insulation, which means value for your money. Rafter vents ensure that the soffit vents remain clear of insulation material so that outside air has a way in through the attic via the soffits and out through the ridge vent. Fresh air should be able to enter your home and stale air to exit. Without free movement of air, moisture that gets trapped inside the attic and mould and mildew will begin to develop.
How to install rafter vents
The first step is to determine how many vents you need. You can calculate this yourself by measuring the area of your home by multiplying the length and width of your house in feet then dividing the area by 150 to get the event space square footage. Divide the figure by two to determine the number of vents you will need.
Rafter vents should be placed in your attic ceiling where the ceiling meets the attic floor. You will need a flashlight, staple gun, and your rafter vents. They also come in varying sizes; four-foot lengths and 14.5 and 22.5-inch widths for different spaces. Staple them directly to the roof decking, and as soon as they are securely in place, place blankets or batts to act as insulation or blow cellulose right to the edge of your attic floor. If you go for blown insulation installation in Toronto, ensure that it does not block the soffits by using additional blockers.
Conclusion:
Rafter vents are crucial for a healthy roof and attic because, without them, the insulation of your home needs will block out the roof vents and increase moisture buildup in the winter and heat accumulation in the summer.
