Loose Fill Insulation Heritage Valley Town Centre Area Edmonton

Loose-fill insulation in Heritage Valley Town Centre Area, measured rather than estimated

Blown-in material fills the awkward parts of an Heritage Valley Town Centre Area 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.

• Existing material assessed — topped up, or removed if it is wet or contaminated
• 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
• Depth read back at the corners, not just where the hatch is
• Even coverage carried right out over the top plates

Loose Fill Insulation Heritage Valley Town Centre Area Edmonton: your questions answered

Do you seal before blowing?

Yes, and it is the step most often skipped. Loose material laid over an open ceiling penetration hides the leak rather than stopping it, and the warm moist air coming through is what wets the insulation from inside.

Does the attic hatch need doing too?

Yes, or it undoes a good part of the rest. It needs an insulated weatherstripped cover and a dam around the opening tall enough to hold the new depth back from spilling through every time it is opened.

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.

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.

Is it too heavy for my ceiling?

Rarely, but worth thinking about on an older lath ceiling or a long unsupported span. Where the ceiling is old or already sagging we would rather use the lighter material at a sensible depth, and sometimes recommend fixing the ceiling first.

Will it block my soffit vents?

Not if baffles go in first. Loose material can also be pushed around by wind at the eaves, so the baffles both hold it clear of the vents and stop the edge being scoured thin — which is exactly where the house loses heat.
