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
  • Insulation to slopes, knee walls and flat ceiling

Questions about room-in-roof insulation in Northumberland

Do you cover the whole of Northumberland?

Yes. We cover every town and village in Northumberland, including Blyth, Cramlington and Ashington.

How do I book a survey in Northumberland?

Send the form or call us. We call back to agree a time and confirm it in writing.

Will the room get smaller?

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

Can it be done without removing the plasterboard?

Sometimes the flat ceiling and eaves voids can be reached from behind. The slopes almost always need the boards off to insulate them properly.
