Loose Fill Insulation Callingwood South

Loose-fill insulation in Callingwood South — settled depth is what you are buying

Blown-in material fills the awkward parts of an Callingwood South 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
• 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

Loose Fill Insulation Callingwood South: 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.

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.

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.

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.

How is old insulation removed?

With a vacuum and hose into sealed bags, not shovels, because disturbing decades of settled material raises a lot of dust. It also gives a clean deck to air-seal and a look at the structure before it is covered again.
