Loose Fill Insulation Mactaggart

Blown-in insulation for Mactaggart 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 Mactaggart 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.

• Baffles at the eaves so soffit venting stays clear
• Depth read back at the corners, not just where the hatch is
• Existing material assessed — topped up, or removed if it is wet or contaminated
• 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

Loose Fill Insulation Mactaggart: 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 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.

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.

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.

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.

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.
