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
  • Insulated plasterboard lining where specified

Questions about rafter insulation in Guildford

Do you charge extra to travel to Guildford?

Not normally. Our guide prices include normal travel to Guildford. 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 Guildford?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

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.

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.
