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 Greenwich

Do you charge extra to travel to Greenwich?

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

Can you visit Greenwich 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.

Do you cover all of SE10?

Yes, we cover the SE10 postcode district and the districts around Greenwich.

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.
