Loft insulation to 270mm and raised boarding, Waterlooville
Loft insulation upgraded from an inadequate 50mm to the full recommended 270mm depth, with raised loft boarding installed above the insulation to preserve the family's storage space. A new loft ladder and light were fitted at the same time.
- 270mm mineral wool insulation
- Raised loft boarding system on legs
- New loft ladder fitted
- New loft light fitted
- Storage space fully preserved
The problem
The loft had only 50mm of insulation — less than a fifth of the current recommended depth of 270mm. The family also used the loft for storage, which meant boarding could not simply be laid on top of the joists without compressing the insulation to nothing.
What we did
We installed 270mm of mineral wool insulation between and over the joists, then built a raised boarding system on legs above it. The boards sit above the insulation, leaving it at full depth underneath. We also fitted a new loft ladder and a loft light so the space is properly accessible and usable.
The result
The family kept their storage space and gained a properly insulated loft. The raised boarding system means the insulation performs at its full rated depth — not compressed to a fraction of it by boards laid flat on the joists.

Raised boarding keeps the insulation at full depth while giving you a usable floor. We fit the insulation, the boards, the ladder and the light in one visit.
