Loose Fill Insulation Silver Berry

Blown-in insulation for Silver Berry attics and closed cavities

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

Loose Fill Insulation Silver Berry: your questions answered

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.

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.

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.

Does loose-fill settle?

Yes, which is why it is specified at a settled depth rather than how it looks on the day. A job blown to look right can measure short a year later. We work to the published settled figure and mark it before starting.

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.
