Loose Fill Insulation Northmount

Loose-fill insulation in Northmount, measured rather than estimated

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

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

Loose Fill Insulation Northmount: your questions answered

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.

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.

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 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.

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.
