Loose Fill Insulation University of Alberta Edmonton

Blown-in insulation for University of Alberta attics and closed cavities

Loose-fill insulation is blown in rather than cut and fitted, which makes it the right answer wherever a batt cannot go: over an irregular University of Alberta attic floor, around trusses and bracing, and into wall cavities that are already closed. What you are paying for is settled depth spread evenly, and that is a thing which can be measured. Depth markers go in before the hose starts, and we read them at the corners rather than in the middle where it is always deepest.

• Settled depth specified and marked before the hose starts
• Ceiling penetrations air-sealed first, not buried
• Baffles at the eaves so soffit venting stays clear
• Existing material assessed — topped up, or removed if it is wet or contaminated
• Even coverage carried right out over the top plates
• Depth read back at the corners, not just where the hatch is

Loose Fill Insulation University of Alberta Edmonton: your questions answered

How messy is it?

Dusty — the machine sits outside and a hose runs through the house to the hatch. We protect the route, seal around the hatch and vacuum afterwards. What the house looks like at the end is most of the difference between crews.

What if you find old wiring?

If we find wiring that must not be covered, we stop and say so rather than blowing over it. That is an electrician's call, not ours, and it is a real reason a job gets paused rather than finished the same day.

How do I know I got what I paid for?

Bag count. Every bag states the area it covers at a given depth, so bags used divided by area is exactly what went in. We keep them, mark the target settled depth, and read the depth back at the corners rather than the middle.

Does loose-fill settle?

Yes, which is why it is specified at a settled depth rather than how it looks on the day. A job blown to look right can measure short a year later. We work to the published settled figure and mark it before starting.

Can you blow insulation into my walls without opening them?

Often yes — dense-pack through small holes, packed hard enough that it does not slump and leave a cold band at the top. The holes then need filling and finishing, which is drywall work, so we quote that with it rather than surprising you.

How is old insulation removed?

With a vacuum and hose into sealed bags, not shovels, because disturbing decades of settled material raises a lot of dust. It also gives a clean deck to air-seal and a look at the structure before it is covered again.
