Attic Ventilation And Baffles In Barrhaven, Ontario

Baffles Keep Attic Ventilation Open Under Deep Insulation

Baffles are stiff channels fastened between rafters right above the soffits. They keep insulation away from the vents and hold open a channel beneath the sheathing for air to rise. Without them, a fresh layer of loose fill slides into the eaves and smothers the vents.

Each vented rafter space gets its own baffle before any insulation is blown, so attic ventilation keeps working once the new layer is in.

Open-Field Wind And Attic Ventilation At The Eaves

Homes facing the fields at the south edge of Barrhaven and out toward Richmond and North Gower take a lot of wind. It pours in through the soffits and shoves loose insulation back from the outside walls, leaving bare drywall along the eaves. The rooms then feel cold beside the exterior walls.

Baffles stop the wind from reaching the insulation while keeping attic ventilation open. They also hold the layer at full depth right out to the edge of the house, where the roof sits lowest.

Bathroom Fans And Attic Ventilation

A bath fan that empties into the attic rather than outside dumps moist air exactly where attic ventilation is meant to keep things dry. We check every fan duct, connect loose ones and run them to an outside vent. The attic air sealing page covers sealing the fan housings at the ceiling.

Attic Ventilation Price Range

Baffles are usually included in a top-up quote. Other attic ventilation work, such as adding roof vents or rerouting fan ducts, is priced per item and often adds $250 to $1,000 to a job in Ontario.
