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.

  • Insulated plasterboard lining where specified
  • Rigid insulation between the rafters, joints taped

Questions about rafter insulation in Sinfin

How do I pay for work in Sinfin?

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

Do you charge extra to travel to Sinfin?

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

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

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

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.
