Attic Insulation Canossa Edmonton

Blown-in attic insulation in Canossa, sealed before it is filled

Attics in Canossa lose depth over time — insulation settles, someone crawls through it for a wiring job, and the corners near the eaves are usually thin to begin with. A top-up is only worth doing if the baffles are clear and the ceiling below is sealed, so that is what we check before quoting.

• Air sealing at pot lights, top plates and the attic hatch
• Baffles kept clear so the soffit vents still breathe
• Blown-in loose-fill to the depth your permit specifies
• Existing insulation levelled before the top-up
• Attic hatch insulated and weatherstripped
• Depth markers left in place so the result is verifiable

Attic Insulation Canossa Edmonton: your questions answered

Do you insulate the attic hatch too?

Yes. It is a direct opening between the house and a space at outdoor temperature, and it is usually the first place we look when someone says a hallway or landing is cold.

My bathroom fan seems to vent into the attic. Is that a problem?

Yes, and it needs correcting before insulating. It dumps warm wet air into the coldest part of the house, and burying it under fresh insulation hides a moisture source that will show up later as frost and staining.

Cellulose or fibreglass?

Both work when installed to depth with the ceiling sealed underneath. Cellulose is denser and resists air movement better; fibreglass is lighter and settles less. We pick based on what is already up there and tell you why.

Why does my Canossa attic frost up in winter?

Almost always warm moist air leaking up from the house through pot lights, top plates or the hatch, then condensing on cold sheathing. More insulation on its own does not fix it — the leaks have to be sealed first.

Should I block the vents to stop drafts?

No. The attic is meant to run close to outdoor temperature so the roof deck stays cold. Blocking soffit vents causes exactly the ice damming people add insulation to prevent.

Can I add over the old insulation?

Usually yes, if it is dry, even and uncontaminated. If it is wet, compacted, rodent-affected or hiding unsealed penetrations, removing it first is worth the cost, and we tell you which one we found.
