Loose Fill Insulation Tweddle Place

Loose-fill insulation in Tweddle Place — settled depth is what you are buying

Blown-in material fills the awkward parts of an Tweddle Place 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.

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

Loose Fill Insulation Tweddle Place: your questions answered

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 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.

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.

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.

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.

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.
