Loose Fill Insulation Thorncliff

Blown-in insulation for Thorncliff attics and closed cavities

Blown-in material fills the awkward parts of an Thorncliff 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
• Ceiling penetrations air-sealed first, not buried
• Existing material assessed — topped up, or removed if it is wet or contaminated
• Settled depth specified and marked before the hose starts
• Even coverage carried right out over the top plates
• Baffles at the eaves so soffit venting stays clear

Loose Fill Insulation Thorncliff: 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.

What about my pot lights?

Older recessed fixtures are not all rated to be covered and loose-fill packs right against them. We check the rating, and where they are not rated they get a proper clearance detail that is also sealed, rather than being buried and hoped about.

Can you just add over what is already up there?

Usually, and it is the best value if the existing material is dry, even and uncontaminated. If it is damp, matted, rodent-affected or hiding unsealed penetrations, adding over it buries the problem — we tell you which one we found.

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.

What do I get when the job is done?

The bag count, the target settled depth, and photographs of the finished space including the corners and the eaves — so you can confirm years later what was actually installed instead of probing a hole and guessing.

How messy is it?

Dusty — the machine sits outside and a hose runs through the house to the hatch. We protect the route, seal around the hatch and vacuum afterwards. What the house looks like at the end is most of the difference between crews.
