Attic Insulation

Attic Spray Foam Insulation In Kitchener, Ontario

Attic spray foam insulation plugs the gaps at the top of the house and adds a layer that holds heat where people live. In an older Kitchener home with a cold bedroom, the attic is the first place we look.

There are two ways to do it. We foam the attic floor, or we foam the roof boards from underneath, and the right choice depends on how the attic is used and how the roof is framed. Your quote names the method, the foam type and the inches for each section.

Attic Insulation details

Icicles Show An Attic Needs Spray Foam Insulation

Long icicles at the eaves and bare spots on a snowy roof both mean warm air is getting into the attic. With more than five feet of snow in an average Kitchener winter, the signs show up early. Meltwater rolls down, freezes over the cold overhang and creeps back under the shingles.

Attic spray foam insulation seals pot lights, wiring holes, plumbing stacks and wall tops, which are the openings that let that warm air up. With those closed, the roof stays cold and the snow sits still.

Attic Spray Foam Insulation On The Roof Boards Or The Floor

Foam on the roof boards brings the attic inside the heated house. We suggest it when the attic holds a furnace or ducts, when it is finished or used for storage, or when the roof has so many angles that the floor is hard to reach.

Sealing the attic floor keeps the attic cold and vented. We spray a sealing coat across the ceiling, then add more insulation on top to reach the depth the house needs. For a plain, open attic, this is the lower-cost way to add attic spray foam insulation.

Westmount Roofs Need Attic Spray Foam Insulation In Small Pockets

Westmount and other older Kitchener neighbourhoods are full of cross-gabled roofs with valleys, dormers and small attic pockets. Batts and blown fill tend to miss the tight corners in those spaces. Attic spray foam insulation follows each angle of the framing, so the small pockets end up as tight as the open ones.

We bring short hoses for tight access and plan the spraying order before the first pass.

Attic Spray Foam Insulation Pricing

Open cell foam across an attic floor or ceiling usually runs $2.50 to $4.50 a square foot. Closed cell sprayed to roof boards usually runs $3.50 to $7 per foot. Attic size, hatch access and target depth decide where your job lands.

Each part of your attic spray foam insulation job gets its own price line on the written quote, so you can choose what to do now and what can wait.

What we spray

Other Areas Worth Sealing

Lots of Kitchener visits end up covering two areas at once, such as the band joist plus the basement walls.

Old wall opened and refilled with spray foam

Wall Insulation

Foam sprayed into open stud bays fills them from edge to edge and stops the drafts older walls let through. The best time to do it is when the plaster or drywall is already off.

Rim Joist Insulation

Sealing the rim joist closes off the wooden band resting on your foundation, a spot that leaks more air than almost anywhere else downstairs. It is a short job that makes a basement far less drafty.

Knee Wall Insulation

Knee wall spray foam insulation seals the short walls and sloped ceilings of an upstairs room tucked under the roof. It fixes the second floor that freezes in winter and bakes in summer.

Spray Foam Removal

Kitchener spray foam insulation removal starts where a bad install left off, with foam that went on wrong and has started to shrink, crack or smell. We cut it back to clean wood so new foam can go on properly.
