Loose Fill Insulation Devon

Blown-in insulation for Devon 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 Devon 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.

• Ceiling penetrations air-sealed first, not buried
• Settled depth specified and marked before the hose starts
• Baffles at the eaves so soffit venting stays clear
• 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
• Even coverage carried right out over the top plates

Loose Fill Insulation Devon: your questions answered

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.

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.

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.

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.

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.

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.
