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 finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.

  • Cables lifted clear of the insulation where possible
  • Mineral wool to 270 to 300 mm across the whole loft floor
  • Area under the cold water tank left clear so it cannot freeze

Questions about loft insulation in Ascot

How do I pay for work in Ascot?

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 Ascot?

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

Is loft work in Ascot different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

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.

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.
