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.

  • Waste packaging removed
  • Eaves kept clear, with ventilation trays where air could be blocked
  • Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Thame

How do I pay for work in Thame?

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

Is loft work in Thame 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.

Do you take on jobs outside Thame?

Yes. We also work in Oxford and Bicester and elsewhere in Oxfordshire.

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.

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.
