Loose Fill Insulation Bonnie Doon

Loose-fill insulation in Bonnie Doon, measured rather than estimated

Blown-in material fills the awkward parts of an Bonnie Doon 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.

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

Loose Fill Insulation Bonnie Doon: 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.

Is it too heavy for my ceiling?

Rarely, but worth thinking about on an older lath ceiling or a long unsupported span. Where the ceiling is old or already sagging we would rather use the lighter material at a sensible depth, and sometimes recommend fixing the ceiling first.

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.

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.
