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 Plymouth

Can a landlord in Plymouth book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Do you take on jobs outside Plymouth?

Yes. We also work in Tavistock and Totnes and elsewhere in Devon.

Is loft work in Plymouth 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.

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.
