Baffle Installation
Baffle Installation
Also known as “wind baffles”, “venting chutes”, “rafter vents”, or “insulation baffles”, baffles provide a channel of air to flow through your exterior soffit vents up through your attic space. The purpose of this airflow is to mix the stale air in your attic, helping to remove moisture and controlling the temperature of your attic.
Baffles are constructed of hardcore waterproof foam and come in 4-foot lengths and 14-1/2 and 22-1/2-inch widths for different rafter spacings. Baffles are installed on your attic ceiling in between the rafters at the point where your attic ceiling meets your attic floor. Common baffle colours are pink, blue, and tan.
Baffles ensure proper airflow into your attic space. Baffles prevent vents from getting clogged by insulation and ensure a clear channel for outside air to move into the attic through soffit vents.
When roof vents allow air to enter and exit the attic, good attic insulation results. Through soffit vents, gable vents, or ridge vents, outside air from the exterior enters the attic. When it does that, moist, stagnant attic air is removed and replaced with fresh, dry air.
Attic insulation without baffles might obstruct soffit vents, limiting the amount of air that the roof ventilation system can suck in.
The significance of proper airflow in your attic
It’s important to have good airflow, especially in the attic. Without enough airflow, you may be vulnerable to moisture buildup, which can lead to mould and mildew issues as well as the musty odour we all associate with attics. If you would like additional information, we do specialize in these areas of proper attic maintenance, including cleaning and insulation. Rotten wood and damage to the structural elements of your attic are the other issues you can have as a result of insufficient ventilation and possibly faulty insulation installation. These issues can be resolved or avoided by using an attic baffle and the appropriate insulation.

How Attic Baffles Benefit Your Roof And Home
- Less Mould and Mildew – Moisture can build up in the attic even with a well-sealed roof. It can build up to the point that mould and mildew spores find an ideal environment to grow if it isn’t removed through ventilation. Mould and mildew eat organic materials like timber rafters and/or a roof deck that support your roof. Over time, they can cause enough damage to the roof to weaken the rafters and/or roof deck.
- Fewer Ice Dams – Ice dams develop when snow and ice on the roof that is higher up melts, rolls down the roof and then refreezes when it flows over the soffit area, which is not heated by the heat of the house. Your roof and eaves troughs may be harmed by ice dams. Ice dams are less likely to form in the attic thanks to good ventilation made possible by baffles that maintain a more constant temperature.
- A Cozier Home – Your home will be warmer in the winter and cooler in the summer if your attic is properly aired, which will improve the effectiveness of the attic insulation.
