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
- Area under the cold water tank left clear so it cannot freeze
- Cables lifted clear of the insulation where possible

Questions about loft insulation in Folkestone
How soon can you visit a home in Folkestone?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Do you cover all of CT20?
Yes, we cover the CT20 postcode district and the districts around Folkestone.
Can a landlord in Folkestone 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.
Does loft insulation need building control approval?
On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
