Loose Fill Insulation Alberta Avenue

Blown-in insulation for Alberta Avenue attics and closed cavities

Blown-in material fills the awkward parts of an Alberta Avenue building that batts leave gapped — around cross-bracing, over the top plates of interior walls, into the shallow triangle at the eaves. It settles over time, which is why it is specified at a settled depth rather than the depth it looks on the day. Air sealing comes first, because loose material laid over an open ceiling penetration hides the leak instead of stopping it.

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

Loose Fill Insulation Alberta Avenue: your questions answered

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.

Cellulose or fibreglass?

Both work. Cellulose is denser, packs into odd shapes and resists air movement through it better; fibreglass is lighter, which matters on a ceiling of uncertain strength. Where there is existing material, matching it is usually simpler than layering the other over it.

Will it make the house quieter?

It noticeably reduces airborne noise from outside — traffic, aircraft, neighbours. It does very little for footsteps from a floor above, which travel through structure, and we would rather say which half it fixes.

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.

What do I get when the job is done?

The bag count, the target settled depth, and photographs of the finished space including the corners and the eaves — so you can confirm years later what was actually installed instead of probing a hole and guessing.

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.
