Full Loft Boarding
Full loft boarding covers most of the accessible loft floor with chipboard or similar boards, usually raised on loft legs above the insulation. It creates a large storage area without compressing the insulation, as long as a ventilation gap is left. A ladder, hatch or lighting can often be added to the same job — check exactly what a quote includes.

Frequently Asked Questions
Will loft boarding compress my insulation?
It should not if the boards are raised on loft legs above the insulation. The Energy Saving Trust advises not squashing mineral wool, because that reduces how well it works, and leaving a small ventilation gap between the insulation and the boards to help prevent condensation.
