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. It earns its place when you need a warm loft. More about rafter insulation.

  • Rigid insulation between the rafters, joints taped
  • Build-up designed for your type of roof underlay
  • Vapour control layer where the design needs one

Questions about rafter insulation in Merseyside

Do you cover the whole of Merseyside?

Yes. We cover every town and village in Merseyside, including Liverpool, Birkenhead and St Helens.

Which council covers my address in Merseyside?

Councils in Merseyside include Knowsley, Liverpool, Sefton, St Helens and others. Your council matters for building control questions and some funding schemes.

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.

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.
