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.

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 about my pot lights?

Older recessed fixtures are not all rated to be covered and loose-fill packs right against them. We check the rating, and where they are not rated they get a proper clearance detail that is also sealed, rather than being buried and hoped about.

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.

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.

Loose Fill Insulation Satoo | Loose Fill Insulation

Blown-in insulation for Satoo attics and closed cavities

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

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

Weight on the ceiling below

Worth a thought

Insulation is light, but a deep layer of dense material over a large Satoo 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.

Satoo drywall in context

About Satoo

Named for a Cree chief, the Mill Woods area was a Cree reserve between 1876-1891.

What we see in Satoo

In Satoo the drywall work is plaster and lath repair, popcorn and stipple ceiling removal, careful patching into original surfaces. We confirm what your home actually needs on site, in writing, before anything starts.

Blowing into a wall that is already closed

Dense-pack

Loose-fill can be blown into closed Satoo wall cavities through small holes, packed to a density that stops it slumping and leaving a cold band at the top.

Where it fits

It suits an older home you do not want to open up. It needs the holes made, filled and finished afterwards, which is drywall work — so quote the patching with it rather than discovering it later.

The hatch, again, because it undoes the rest

The one gap left

You can blow a perfect even depth across an Satoo 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.

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 Satoo 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.

Pot lights buried in loose material

A heat question

Older recessed fixtures are not all rated to be covered, and loose-fill packs right against them.

What we check

Whether the Satoo fixtures are rated for insulation contact. Where they are not, they get a proper clearance detail rather than being buried and hoped about — and that detail is also a sealed one, so it does not become a new air leak.

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 Satoo 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.
