Loose Fill Insulation Callaghan

Blown-in insulation for Callaghan 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 Callaghan 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.

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

Loose Fill Insulation Callaghan: your questions answered

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.

My bathroom fan vents into the attic. Does that matter?

A great deal — it is the fastest way to soak an attic from inside. We look for it while the space is open and flag it before covering anything rather than blowing over the top of 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.

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.

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.

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.
