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 Feltham

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

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

Is loft work in Feltham 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.

Do you take on jobs outside Feltham?

Yes. We also work in Hounslow and Twickenham and elsewhere in Greater London.

Will the room get smaller?

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

How long does room-in-roof insulation take?

Usually three to six working days for one room, depending on how much is stripped and how it is finished.
