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 Cowes

Is loft work in Cowes 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 cover all of PO31?

Yes, we cover the PO31 postcode district and the districts around Cowes.

Do you take on jobs outside Cowes?

Yes. We also work in Newport (Isle of Wight) and Ryde and elsewhere on the Isle of Wight.

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.

Will the room get smaller?

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