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
- Boarding and finishing as agreed on the quote

Questions about room-in-roof insulation in Hampshire
Do you cover the whole of Hampshire?
Yes. We cover every town and village in Hampshire, including Southampton, Portsmouth and Basingstoke.
How do I book a survey in Hampshire?
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.
