What is loft insulation?
We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.
- Mineral wool to 270 to 300 mm across the whole loft floor
- Eaves kept clear, with ventilation trays where air could be blocked
- Cables lifted clear of the insulation where possible

How deep should loft insulation be?
The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.
Do I need to empty my loft first?
The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.
