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
  • Eaves voids insulated where accessible
  • Boarding and finishing as agreed on the quote

Questions about room-in-roof insulation in Canvey Island

Do you cover all of SS8?

Yes, we cover the SS8 postcode district and the districts around Canvey Island.

Can you visit Canvey Island outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Is loft work in Canvey Island 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.

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.
