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.

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

Questions about room-in-roof insulation in Yarmouth

Do you charge extra to travel to Yarmouth?

Yarmouth is reached by ferry, so travel is priced separately and shown on the quote before you book.

How soon can you visit a home in Yarmouth?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

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

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

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.
