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.

  • Waste packaging removed
  • Area under the cold water tank left clear so it cannot freeze
  • Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Barnstaple

How do I pay for work in Barnstaple?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

Can you visit Barnstaple outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Do you take on jobs outside Barnstaple?

Yes. We also work in Bideford and Ilfracombe and elsewhere in Devon.

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 long does it take to insulate a loft?

Most lofts in houses take a single day. A large bungalow loft, a loft that needs clearing first or one with awkward access can run into a second day.
