Blown-in insulation for Callaghan 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 Callaghan 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 versus installed depth

The number that counts

Loose-fill settles after installation. A job blown to look right on the day can be measurably short a year later.

How it is specified

The manufacturer publishes a settled depth and the bag count needed to reach it over a given area. We work to that and mark it, rather than blowing until the Callaghan attic looks full.

Callaghan drywall in context

What we see in Callaghan

In Callaghan 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.

What we hand over at the end

Evidence, not assurances

Bag count, target settled depth, and photographs of the finished Callaghan space including the corners and the eaves.

Why it matters later

It is what lets you or anyone else confirm years afterwards what was actually installed, rather than probing a hole in the ceiling and guessing.

Access, hoses and how much of the house we cross

Practical reality

The machine sits outside and a hose runs to the Callaghan attic hatch, which usually means through a hallway or a closet.

Keeping it clean

Protected route, sealed hatch surround, the space vacuumed after. It is a dusty trade and the difference between a good crew and a bad one is mostly what the house looks like at the end.

Bag count is the honest check

Coverage is arithmetic

Every bag states the area it covers at a given depth. Bags used, divided by area, tells you exactly what was installed.

Why we keep them

Depth can be probed in a few spots and averaged; the bag count cannot be argued with. On an Callaghan attic it is the simplest proof that what was quoted is what went in.

Weight on the ceiling below

Worth a thought

Insulation is light, but a deep layer of dense material over a large Callaghan ceiling is still a load, particularly on an older lath ceiling or a long unsupported span.

How we handle it

Where the ceiling is old or already sagging, the lighter material and a sensible depth beat the deepest possible number. Fixing the ceiling first is sometimes the honest recommendation.

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 Callaghan 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.

Loose Fill Insulation Callaghan Edmonton: your questions answered

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.
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.
Can I still store things in the attic?
Only over a raised platform. Anything laid straight on the joists compresses the material and cuts a thin channel through the middle of the ceiling. Otherwise a fully insulated attic is not also a storage room.
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.
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.
My bathroom fan vents into the attic. Does that matter?
A great deal — it is the fastest way to soak an attic from inside. We look for it while the space is open and flag it before covering anything rather than blowing over the top of it.
