Barrie winters are long and cold, and a thin attic lets your heat escape straight through the roof. Blown-in fiberglass is one of the fastest, most affordable ways to bring a Barrie attic up to the R-60 standard. Pro Insulation Contracting installs Owens Corning and Johns Manville blown-in fiberglass throughout Barrie — licensed, BBB-accredited, 4.9★ rated.
Barrie sits in one of the colder pockets of southern Ontario — long winters, real snow load off Lake Simcoe, and heating seasons that stretch from November well into March. In those conditions, the attic is where homes leak the most heat. If your upstairs is freezing while the main floor is comfortable, or your gas bill climbs every January, a thin or settled attic is usually the cause.
Blown-in fiberglass is loose-fill insulation made from spun glass fibres — glass and sand processed into a light, fluffy material. It’s blown into your attic with a machine, so it fills around joists, wiring, and corners and settles into an even blanket. It’s lighter than cellulose, naturally fire- and water-resistant, and one of the most affordable ways to add real R-value. For a lot of Barrie attics — especially straightforward top-ups — it’s the practical choice.

Ontario’s Building Code sets a minimum of R-60 for attic insulation in new construction, and it’s the level worth targeting in any Barrie home. Because fiberglass has a slightly lower R-value per inch than cellulose, reaching R-60 with blown-in fiberglass takes roughly 20 to 24 inches of settled depth. We measure what’s already up there first — in most homes, new fiberglass goes right over the old layer and the R-values add together, so removal usually isn’t needed.
Plenty of older Barrie homes were built to standards well below R-60, and newer south-end subdivisions were often built to the minimum and no more. Either way, the gap shows up on your heating bill.
Fiberglass is excellent for attic top-ups where the existing insulation is thin but clean, for budget-conscious projects that still need to hit R-60, and for large open attic floors where blown-in coverage is fast and even.
What it doesn’t do is air-seal. If your real problem is drafts, a cold room over the garage, or attic moisture, fiberglass alone is a partial fix — it insulates well but doesn’t stop air movement the way spray foam does. We’ll tell you that at the inspection rather than overselling a top-up that won’t solve the actual issue.
Pros
Cons
Both reach R-60 and both are rebate-eligible. Cellulose is denser and needs less depth; fiberglass is lighter and usually more affordable. We recommend based on your specific attic, not a default.
Yes — Barrie is part of our regular service area. We’re based in Markham and work throughout the region.
Roughly 20–24 inches of settled material to reach R-60, the Ontario attic standard.
Only if it’s contaminated by mould, water, or rodents. Otherwise we blow new fiberglass over the existing layer and the R-values add together.
It insulates well but doesn’t air-seal on its own. If drafts are the main issue, we may recommend pairing it with air sealing — we’ll explain at the inspection.
No. We don’t use hazardous materials, so you and your family can stay home.
