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.

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.

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.

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.

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.

Is blown-in better than batts?

In an attic, usually yes, because it flows around trusses, bracing and wiring where batts get cut short or forced and leave gaps. In open framed walls at regular spacing, batts are fine. We recommend by the space, not by what is on the truck.

Loose Fill Insulation Ermineskin

Blown-in insulation for Ermineskin attics and closed cavities

Blown-in material fills the awkward parts of an Ermineskin 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
Even coverage carried right out over the top plates
Existing material assessed — topped up, or removed if it is wet or contaminated
Baffles at the eaves so soffit venting stays clear
Depth read back at the corners, not just where the hatch is
Ceiling penetrations air-sealed first, not buried

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 Ermineskin 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.

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 Ermineskin attic looks full.

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 Ermineskin attic it is the simplest proof that what was quoted is what went in.

Filling around bracing and trusses

Why batts fail here

Truss webs, cross-bracing and wiring turn an Ermineskin attic floor into a shape no rectangle fits. Batts get cut short or forced, leaving gaps.

What blown-in does

It flows around all of it and fills to a consistent depth. This is the single clearest reason to choose loose-fill over batts above a ceiling.

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 Ermineskin 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.

Access, hoses and how much of the house we cross

Practical reality

The machine sits outside and a hose runs to the Ermineskin 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.
