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
  • Rigid insulation between the rafters, joints taped
  • Vapour control layer where the design needs one

Questions about rafter insulation in the Forth Valley

Are your prices the same across the Forth Valley?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

Do you cover the whole of the Forth Valley?

Yes. We cover every town and village in the Forth Valley, including Stirling, Falkirk and Alloa.

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.
