Loose Fill Insulation Twin Brooks

Blown-in insulation for Twin Brooks attics and closed cavities

Blown-in material fills the awkward parts of an Twin Brooks 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.

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

Loose Fill Insulation Twin Brooks: 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.

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.

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.

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.

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.
