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. We check the roof underlay first: a breathable membrane and a felt with no ventilation gap need different build-ups to avoid condensation. More about rafter insulation.

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

Questions about rafter insulation in Grays

Will I get a written quote for work in Grays?

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

Do you charge extra to travel to Grays?

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

Can you visit Grays 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.

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.
