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
  • Vapour control layer where the design needs one
  • Build-up designed for your type of roof underlay

Questions about rafter insulation in Longfield

Do you take on jobs outside Longfield?

Yes. We also work in Swanscombe and Gravesend and elsewhere in Kent.

How do I pay for work in Longfield?

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

Will I get a written quote for work in Longfield?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

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.
