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.
- Vapour control layer where the design needs one
- Rigid insulation between the rafters, joints taped
- Insulated plasterboard lining where specified

Questions about rafter insulation in Carmarthen
Do you take on jobs outside Carmarthen?
Yes. We also work in Llanelli and Ammanford and elsewhere in Dyfed.
How do I pay for work in Carmarthen?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Can you visit Carmarthen 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.
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.
