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.

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

Questions about rafter insulation in Cheltenham

Can a landlord in Cheltenham book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Can you visit Cheltenham 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.

How do I pay for work in Cheltenham?

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.

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.
