Blown-In Attic Insulation In Barrie, Ontario

Batts Leave Gaps That Blown-In Attic Insulation Fills

Rolls of batts are cut to fit between the joists, and every cut leaves a seam. Around trusses, wiring and the hatch frame, those seams turn into open gaps where heat escapes. Blown-in attic insulation flows into those gaps and leaves one continuous layer across the floor.

That matters most over the bedrooms at the edge of the house, where the rafters drop close to the ceiling and batts are hardest to fit.

Cellulose Or Fibreglass For Blown-In Attic Insulation

Cellulose starts as recycled newsprint and is treated with borate against fire and mould. It is dense, so it slows air movement inside the layer and settles a little in the first year. Fibreglass is lighter, does not absorb water and settles less. Both reach R-60 when blown deep enough.

We recommend one on the visit based on your attic. A low attic with little headroom often suits cellulose. An attic with a history of roof leaks often suits fibreglass.

Blown-In Attic Insulation Is Checked Across The Whole Attic

Before the hose comes up, we staple depth rulers to trusses across the attic floor, including the far corners and the edges near the eaves. Blown-in attic insulation goes in until every ruler shows the same number. You get a photo of the rulers and the reading on your invoice.

Many Barrie attics are a mix of old batts in one spot and thin loose fill in another. The rulers make sure blown-in attic insulation fills the low spots, not just the area near the hatch.

Blown-In Attic Insulation Pricing

Taking an empty attic all the way to R-60 typically lands at $1.75 to $3.00 for each square foot of floor. Blown-in attic insulation over an existing layer costs less, because less material goes in. Your emailed quote sets the actual figure. Read what moves the attic insulation cost for more detail.
