Blown insulation: for low lofts that are hard to get into
Loose fibres are blown in through a hose, settling into an even blanket. It’s the answer for low or awkward lofts where rolls are hard to lay.

| Good for | Low lofts, awkward corners, shallow pitches |
| Worth knowing | Needs the eaves protected and depth markers fitted |
When we blow it in
Some lofts are too low or cramped to crawl around laying rolls. Blowing loose fibres through a hose lets the insulation reach every corner with someone working from near the hatch.
How it’s done
We fit trays at the eaves so the fibres can’t block the airflow, put up depth markers so you can see how deep it is, then blow the fill evenly across the floor.
Things to know
A blown loft isn’t one to walk on or store things in. If you want storage too, we’ll suggest a raised floor over part of it.
