Blown-In Cellulose Insulation
Blown-in cellulose insulation fills every gap between joists and trusses, so the top floor of a Kanata house keeps its heat. It is the material we quote most often for attic top-ups.

Ontario attic rebates up to $1,250 may applyBlown-in fiberglass insulation is loose glass fibre blown through a hose into the attic, where it builds a light, even layer over the ceiling. It does not absorb water and it does not settle much, which makes it a steady choice for an attic that will be left alone for decades.
It is the white or pink fluff many people picture when they think of attic insulation. Unlike batts, blown-in fiberglass insulation flows around trusses, wires and ducts without leaving the gaps that cut the R-value of a batt job.
Blown-In Fiberglass Insulation details
How Deep Blown-In Fiberglass Insulation Needs To Be
Fiberglass needs more depth than cellulose for the same R-value. To reach R-60, most products call for a little over 20 inches of blown-in fiberglass insulation. We follow the bag chart for the exact product and set depth rulers across the attic so the finished level is easy to check.
That height matters near the eaves. We fit baffles first so the deeper layer cannot slide into the soffit vents. The attic ventilation and baffles page explains why those vents need to stay open.
Where Blown-In Fiberglass Insulation Fits Best
Fiberglass suits attics with a lot of wiring or ductwork, because it is light and easy to move aside for a future repair. It also suits newer Kanata homes in Morgan's Grant and Kanata Lakes that already have fiberglass up there, since the top-up matches what is already in place.
Some owners choose fiberglass because it is not made of paper and does not absorb water. Others prefer cellulose for its density. Our blown-in cellulose insulation page covers that side.
Air Sealing Comes Before The Fiberglass
Air drifts through loose glass fibre more freely than through cellulose, so an unsealed ceiling undercuts it badly. Every penetration, from pot light cans to the vent stack, is closed off first, and only then does the blown-in fiberglass insulation go on.
Blown-In Fiberglass Insulation Price
In Ontario, blown-in fiberglass insulation generally runs $1.50 to $3 a square foot of ceiling area. Because it needs more inches for the same R-value, it tends to cost slightly more than cellulose. The quote spells out the inches, the R-value and the area.

Work That Often Goes With This Job
Most Kanata attics get two or three of these done in the same visit, which saves a second trip.
Attic Insulation Replacement
Attic insulation replacement is a clear-out and a refill: the old layer is vacuumed away, the attic is cleaned, and new loose fill goes in to R-60. It is the answer when the existing material is soaked, mouldy, fouled by animals or crushed flat.

Attic Air Sealing
Attic air sealing plugs the holes in your top-floor ceiling where heated indoor air sneaks up under the roof. Loose fill slows heat soaking through drywall, yet air pours through an open hole as if the fill were not there.

Attic Hatch Insulation
Attic hatch insulation turns the thin panel in your closet or hallway ceiling into a sealed, insulated door. A bare hatch is often a single layer of drywall resting loosely on a wood frame.

Attic Ventilation And Baffles
Attic ventilation lets outside air enter at the soffits and leave near the peak, which keeps the attic close to the outdoor temperature and carries moisture away. A cold, dry attic means snow melts less from below, the roof boards stay sound and the insulation stays dry.

Bonus Room Insulation
Bonus room insulation fixes the room that sits over an attached garage and never feels like the rest of the house. That room has a cold garage under its floor, short knee walls with attic space behind them and a sloped ceiling under the roof.

Ontario Attic Insulation Rebate
Ontario's attic insulation rebate is part of Home Renovation Savings, a joint effort of Enbridge Gas and Save on Energy. It returns money to owners who take a thin attic to R-50 or better.

Attic Insulation Cost
Attic insulation cost in Kanata comes down to four things: square footage, material, the depth already there and whether old fill must come out.
