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
  • Eaves kept clear, with ventilation trays where air could be blocked
  • Area under the cold water tank left clear so it cannot freeze

Questions about loft insulation in Falmouth

How do I pay for work in Falmouth?

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

Will I get a written quote for work in Falmouth?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Do you cover all of TR11?

Yes, we cover the TR11 postcode district and the districts around Falmouth.

Can you insulate around downlights?

Recessed downlights need clearance or a fire-rated cover so they do not overheat. We fit covers where needed and leave a clear zone around fittings that cannot be covered.

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.
