Blown-in insulation for Edgemont attics and closed cavities

Blown-in material fills the awkward parts of an Edgemont 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.

The hatch, again, because it undoes the rest

The one gap left

You can blow a perfect even depth across an Edgemont ceiling and still lose heat through an uninsulated hatch that loose material spills through every time it opens.

What it needs

An insulated, weatherstripped cover and a dam around the opening high enough to hold the new depth back.

Edgemont drywall in context

What we see in Edgemont

In Edgemont the drywall work is first-year settling, basement dev for first owners, Level 5 over builder-grade. We confirm what your home actually needs on site, in writing, before anything starts.

The material must not block the eaves

Loose material moves

Unlike a batt, blown-in can be pushed by wind washing at the eaves and drift away from where it was placed.

Baffles, every time

Baffles hold it back from the soffit vents and stop wind scouring the edge thin. In an Edgemont attic that band above the exterior wall is exactly where the house loses heat, so it is the last place to accept a thin spot.

Cellulose or fibreglass, and when it matters

Two common materials

Cellulose is recycled paper treated for fire and pests; loose-fill fibreglass is the same glass wool as a batt, chopped. Both work.

How we choose for an Edgemont attic

Cellulose is denser, packs into odd shapes well and resists air movement through it better. Fibreglass is lighter, which matters on a ceiling of uncertain strength. Where the existing material is one of them, matching it is usually simpler than layering the other over top.

Working in a cathedral or a low attic

Not every space suits it

A vented sloped ceiling needs its air channel kept clear, and a shallow attic may not have room for the hose or the depth.

Being straight about it

Where an Edgemont roof space cannot take a proper depth without blocking ventilation, we say what the space can actually achieve instead of quoting a number the geometry will not allow.

Removing old loose-fill

A vacuum job, not a shovel job

Old blown-in comes out with a vacuum and hose into sealed bags, because disturbing decades of settled material makes a great deal of airborne dust.

What it buys

A clean deck to air-seal properly and, in older Edgemont homes, the chance to see the ceiling structure and any past leaks before they are covered again.

Storage areas and the platform question

The trade-off is real

Anything laid on the joists compresses loose-fill and cuts a thin channel through the middle of an Edgemont ceiling.

Doing it properly

If storage is genuinely needed, a raised platform over a limited area lets full depth continue underneath. Otherwise the honest answer is that a fully insulated attic is not also a storage room.

Loose Fill Insulation Edgemont Edmonton: your questions answered

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.
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.
Can you just add over what is already up there?
Usually, and it is the best value if the existing material is dry, even and uncontaminated. If it is damp, matted, rodent-affected or hiding unsealed penetrations, adding over it buries the problem — we tell you which one we found.
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.
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.
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.
