Attic Insulation Blue Quill Edmonton

Attic insulation in Blue Quill: air seal first, then blow

The most common mistake in an Blue Quill attic is blowing insulation over an unsealed ceiling. Warm moist air keeps rising through pot lights, top plates and the hatch, and it carries moisture into cold insulation where it condenses. We air-seal the penetrations first, then insulate.

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

Attic Insulation Blue Quill Edmonton: your questions answered

Do you insulate over an addition or a vaulted ceiling?

Those need looking at specifically rather than quoting an average depth. Shallow attics, cathedral sections and knee walls are usually the coldest rooms in an Blue Quill house and the parts a general top-up misses.

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.

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.

How much insulation should my Blue Quill attic have?

The depth comes from what the code asks for on your permit, not from us. What we can tell you is the depth you have now, whether it is even, and whether the eaves and hatch are dealt with — those three often matter more than the last few inches.

I store things in my attic. Can I keep doing that?

Yes, but the plywood squashes the insulation beneath it to joist depth. Either the storage area gets raised on a platform above the finished depth, or it stays as a deliberately weaker zone kept small. We will not top up around it and pretend it is not there.

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.
