Attic Spray Foam Insulation In Doon, Ontario

Warm Air Escapes Through The Attic Floor

Pot lights, bathroom fans, plumbing vents, wire holes and the tops of interior walls all open the ceiling to the attic. Warm, damp air slips through each one.

That air carries heat away, and when the weather turns bitter its moisture freezes onto the roof boards. A mild day melts the frost, and it drips back down onto the insulation. Sealing the openings with attic spray foam insulation ends that loop.

Two Ways To Insulate An Attic With Foam

Attic spray foam insulation can follow one of two routes. The first approach keeps the attic cold. A layer of closed cell foam seals the ceiling from above, then blown-in material adds most of the depth. This is the most common attic spray foam insulation job and the best value for an ordinary attic.

The second approach brings the attic inside the house. Foam goes on the roof sheathing, turning the attic into a sealed, conditioned space. It suits attics that hold ductwork or a furnace, and it costs more. During the visit we tell you which route your attic should take.

How Much Depth Your Attic Needs

New Ontario homes are built to about R-50 in the attic. Houses in Pioneer Park often hold far less, and what is there has packed down over fifty years. We measure the current depth, show you the shortfall and print the target R-value on the attic spray foam insulation quote.

Snow On The Roof Shows Where Heat Is Leaking

Kitchener sees about 63 inches of snow in a normal winter. When warm air leaks into the attic, snow melts off the roof in patches and freezes again at the eaves. With attic spray foam insulation in place the roof boards stay cold, so the snow sits evenly and less ice forms along the gutters.

Attic Spray Foam Insulation Cost

Provincial pricing for attic foam tends to fall from $2.50 to $4.50 a square foot with open cell over a sealed floor, and from $3.50 to $7 when closed cell goes against the sheathing. Your written quote, sent after the visit, names the product, the inches and the area.
