Loose Fill Insulation Miller

Loose-fill insulation in Miller — settled depth is what you are buying

Blown-in material fills the awkward parts of an Miller 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.

• 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
• Ceiling penetrations air-sealed first, not buried
• Even coverage carried right out over the top plates
• Existing material assessed — topped up, or removed if it is wet or contaminated

Loose Fill Insulation Miller: your questions answered

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.

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.

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.

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.

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.
