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
- Insulated plasterboard lining where specified

Questions about rafter insulation in Cambridge
How soon can you visit a home in Cambridge?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Will I get a written quote for work in Cambridge?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you take on jobs outside Cambridge?
Yes. We also work in Royston and St Ives (Cambridgeshire) and elsewhere in Cambridgeshire.
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.
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.
