Loose Fill Insulation Blackburne

Blown-in insulation for Blackburne 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 Blackburne 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.

• Even coverage carried right out over the top plates
• Baffles at the eaves so soffit venting stays clear
• Existing material assessed — topped up, or removed if it is wet or contaminated
• 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

Loose Fill Insulation Blackburne: your questions answered

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.

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.

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.

Will it make the house quieter?

It noticeably reduces airborne noise from outside — traffic, aircraft, neighbours. It does very little for footsteps from a floor above, which travel through structure, and we would rather say which half it fixes.

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.

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.
