What is room-in-roof insulation?

Most rooms-in-roof are reached by stripping the existing plasterboard on the slopes, fitting insulation between and over the rafters, and re-boarding. Where there is access behind the knee walls, we insulate the eaves voids and the floor behind them too. More about room-in-roof insulation.

  • Boarding and finishing as agreed on the quote
  • Eaves voids insulated where accessible

Questions about room-in-roof insulation in Crowthorne

Is loft work in Crowthorne 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.

Will I get a written quote for work in Crowthorne?

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

What do I need to do before you arrive in Crowthorne?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Will the room get smaller?

Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.

How long does room-in-roof insulation take?

Usually three to six working days for one room, depending on how much is stripped and how it is finished.
