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.

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

Questions about rafter insulation in Dorking

Do you charge extra to travel to Dorking?

Not normally. Our guide prices include normal travel to Dorking. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

How do I pay for work in Dorking?

How soon can you visit a home in Dorking?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

Can I use the loft as a bedroom after rafter insulation?

Insulation alone does not make a loft habitable. Fire escape, stairs, floor strength and headroom all come into a conversion, which needs building control.

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.
