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.

  • Cables lifted clear of the insulation where possible
  • Tank jacket and pipe lagging in the loft
  • Eaves kept clear, with ventilation trays where air could be blocked

In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.

Questions about loft insulation in Exeter

What do I need to do before you arrive in Exeter?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Do you take on jobs outside Exeter?

Yes. We also work in Exmouth and Tiverton and elsewhere in Devon.

Can a landlord in Exeter book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Will loft insulation make my loft colder?

Yes, and that is expected. The insulation keeps the heat in the rooms below, so the loft above runs closer to the outdoor temperature. That is why pipes and the tank are lagged as part of the job.

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.
