Insulation

Attic, Wall & Floor Upgrades

Retrofit Without Tearing It Open

Blown-in insulation is a versatile solution perfect for upgrading existing walls and attics without the need for extensive renovation. It reaches the irregular spaces and awkward cavities that other materials cannot, improving both thermal efficiency and soundproofing.

Batt insulation comes in pre-cut panels that fit snugly between studs and joists, effectively reducing heat transfer. Both are designed for use in various parts of a building, including attics, walls, and floors — so we match the material to the cavity rather than the other way around.

Attics

Where most Algoma homes lose the most heat, and where an upgrade pays back fastest. Blown-in tops up thin or settled existing insulation without a rebuild.

Walls

Existing walls upgraded from the outside or through small access points — no gutting the interior to reach the cavity.

Floors

Batt between joists over crawl spaces, unheated garages, and cold basements, where cold floors are the symptom.

Soundproofing Too

The same upgrade that holds heat in also keeps noise out — between floors, or between you and the road.

Materials we work with

Blown wool, fiberglass, and cellulose
Batt in fiberglass, mineral wool, and cotton
Open-cell and closed-cell spray foam where the cavity calls for it
