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.

Questions about rafter insulation in Sunbury-on-Thames

Do you take on jobs outside Sunbury-on-Thames?

Yes. We also work in Walton-on-Thames and Ashford (Surrey) and elsewhere in Surrey.

Can you visit Sunbury-on-Thames 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.

Can a landlord in Sunbury-on-Thames book work for a tenanted house?

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

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.

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.
