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.

  • Insulation to slopes, knee walls and flat ceiling
  • Eaves voids insulated where accessible
  • Boarding and finishing as agreed on the quote

Questions about room-in-roof insulation in Kettering

Do you cover all of NN16?

Yes, we cover the NN16 postcode district and the districts around Kettering.

Will I get a written quote for work in Kettering?

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.

Will the room get smaller?

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