Loose Fill Insulation McKernan

Blown-in insulation for McKernan attics and closed cavities

Loose-fill insulation is blown in rather than cut and fitted, which makes it the right answer wherever a batt cannot go: over an irregular McKernan attic floor, around trusses and bracing, and into wall cavities that are already closed. What you are paying for is settled depth spread evenly, and that is a thing which can be measured. Depth markers go in before the hose starts, and we read them at the corners rather than in the middle where it is always deepest.

• Depth read back at the corners, not just where the hatch is
• Even coverage carried right out over the top plates
• Settled depth specified and marked before the hose starts
• 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 McKernan: your questions answered

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.

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.

How do I know I got what I paid for?

Bag count. Every bag states the area it covers at a given depth, so bags used divided by area is exactly what went in. We keep them, mark the target settled depth, and read the depth back at the corners rather than the middle.

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 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.

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.
