What is rafter insulation?

Because the whole roof slope, the gables and the party walls now have to be insulated, this costs much more than insulating the floor and saves less heat for the money. We check the roof underlay first: a breathable membrane and a felt with no ventilation gap need different build-ups to avoid condensation. More about rafter insulation.

  • Build-up designed for your type of roof underlay
  • Rigid insulation between the rafters, joints taped
  • Insulated plasterboard lining where specified

Questions about rafter insulation in Cambridgeshire

Do you cover the whole of Cambridgeshire?

Yes. We cover every town and village in Cambridgeshire, including Peterborough, Cambridge and Wisbech.

Can you quote for several properties in Cambridgeshire?

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.

Will it cause condensation?

It can if the build-up is wrong for the roof. Old bitumen felt needs a ventilation gap behind the insulation; a modern breathable membrane may not. We check before we design it.

Is insulating between the rafters better than the loft floor?

Not for saving energy alone. Insulating the floor heats less space and costs far less. Rafter insulation is the right answer when the loft itself needs to be warm.
