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 Gerrards Cross
How do I pay for work in Gerrards Cross?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you cover all of SL9?
Yes, we cover the SL9 postcode district and the districts around Gerrards Cross.
Will I get a written quote for work in Gerrards Cross?
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.
