Blown-in attic insulation spreads an even layer over the entire attic floor, around wires and trusses, while a clean existing layer stays in place.

It is the job we are asked for most. The loose fill rides a hose from our truck up into the attic, so it reaches the low corners at the eaves that batts and arms cannot. We use blown fiberglass or cellulose depending on the attic, and the quote says why.

Blown-In Attic Insulation Starts With A Sealed Floor

Before any bag is opened, the attic floor gets sealed. Top plates, wire holes, the plumbing stack, fans and the hatch are closed so warm air stops rising through the ceiling. The new layer then rests on a tight floor instead of a leaky one.

This step adds a few hours to the job, and it is why the new layer performs the way the label says. The attic air sealing page lists every opening we close.

Fiberglass Or Cellulose For Blown-In Attic Insulation

Either material gets to R-60 at the right depth. Blown fiberglass is light, shrugs off water and holds its height well. Cellulose is heavier and denser, so air has a harder time moving through it, and it slumps slightly after install, so we add extra to allow for that.

In most Barrhaven attics either one works. We recommend one based on the existing layer, the ceiling and the trusses, and the price for each is written on the quote when you want to compare.

How Deep Blown-In Attic Insulation Goes

The depth depends on what is already there and the R-value you want. Going from bare drywall to R-60 means about 16 to 22 inches of blown-in attic insulation, and the product's bag chart sets the exact figure. Over a few inches of old fill, the top-up is less.

Depth markers get stapled to the trusses ahead of blowing, so the finished height shows in the photos. The bag count on the quote matches that depth. The R-60 attic insulation page goes into the numbers.

Blown-In Attic Insulation Price Range

In Ontario, a blown-in top-up over an existing layer tends to cost $1.40 to $2.60 per square foot. For a 1,000 square foot Barrhaven attic, expect roughly $1,400 to $2,600, with the sealing, baffles and hatch shown on their own lines.
