Loose Fill Insulation Delwood

Blown-in insulation for Delwood attics and closed cavities

Blown-in material fills the awkward parts of an Delwood 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
• Depth read back at the corners, not just where the hatch is
• Settled depth specified and marked before the hose starts
• Baffles at the eaves so soffit venting stays clear
• Even coverage carried right out over the top plates
• Ceiling penetrations air-sealed first, not buried

Loose Fill Insulation Delwood: your questions answered

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 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 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 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.

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.
