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 Keynsham
Do you take on jobs outside Keynsham?
Yes. We also work in Bath and Nailsea and elsewhere in Somerset.
Can a landlord in Keynsham book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
How do I pay for work in Keynsham?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
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.
