Cellulose attic insulation is blown in as loose fill and settles into a dense, even layer across the whole attic floor. It reaches the low corners at the eaves where batts often stop short.

Cellulose is made mostly from recycled paper treated with borate for fire and pest resistance. It is the material we use most in Orléans attics.

Cellulose Attic Insulation Details

Batts Leave Gaps That Cellulose Fills

A batt is cut to length, and each cut leaves an edge that air can slip past. Wires, trusses and vent pipes make tidy cuts nearly impossible, so older batt attics tend to leak at every seam.

Cellulose attic insulation flows around those obstacles. It also slows air moving through the layer itself, which helps on windy winter nights.

Cellulose Attic Insulation Goes In From One Hose

The blowing machine stays outside or in the garage, and a single hose runs to the attic hatch. Inside the house, the only thing you see is the covered path from the door to the hatch.

We blow from the far corners back toward the hatch, check the depth against markers, and leave the hatch weatherstripped and insulated.

Settling Is Planned For In Advance

Loose cellulose settles a little in its first months. We blow it to the installed depth that gives your target R-value after settling, so an R-60 attic stays at R-60.

Ask us about an attic insulation top-up if your attic already has an older layer we can build on.

Cellulose Attic Insulation Pricing

For an empty or nearly empty attic, cellulose attic insulation usually runs $1.75 to $3 per square foot at Ontario market rates. Adding cellulose attic insulation over an existing layer costs less, and your written quote gives the firm number.

Attic Insulation Top-Up To R-60

An attic insulation top-up blows fresh cellulose over the layer already in place and lifts the attic to R-60. For a chilly top floor in an older Orléans house, it is the quickest fix there is.

Old Attic Insulation Removal

Attic insulation removal pulls out old fill that is flattened, dirty or damaged, so the attic can be sealed and refilled properly. It leaves through a sealed vacuum hose and goes away in bags.

Attic Air Sealing

Attic air sealing plugs the openings between your living space and the attic above. Heated air rises out through pot lights, wire holes, vent stacks and the hatch, carrying moisture along with it.

Ice Dam Prevention

Ice dams start when warmth leaking out of the house softens roof snow from underneath and the water freezes again at the cold overhang. Ice dams then hold back more meltwater, which can creep under the shingles and stain the ceiling.

Wet And Mouldy Insulation

Wet attic insulation holds little heat, and left damp it can feed mould on the roof boards. We find out where the water came from, take out the damaged material, and reinsulate once the wood is dry.

Vermiculite Insulation

Vermiculite insulation is a light, pebbly loose fill in silver-gold to grey-brown. Some vermiculite insulation sold in Canada before 1990, including the Zonolite brand, came from a mine with natural asbestos in it. Not all of it contains asbestos, and nobody can tell by looking.

Attic Insulation Rebate

The Ontario attic insulation rebate comes from the Home Renovation Savings program, run across the province by Save on Energy together with Enbridge Gas. Its attic-only stream pays up to $1,250 once a thin attic is brought to R-50, and it does not ask for a home energy assessment first.
