Loose Fill Insulation Jamieson Place

Blown-in insulation for Jamieson Place 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 Jamieson Place 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.

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

Loose Fill Insulation Jamieson Place: your questions answered

How messy is it?

Dusty — the machine sits outside and a hose runs through the house to the hatch. We protect the route, seal around the hatch and vacuum afterwards. What the house looks like at the end is most of the difference between crews.

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.

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.

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.

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.

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.
