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
- Build-up designed for your type of roof underlay
- Vapour control layer where the design needs one

Questions about rafter insulation in Pwllheli
Is loft work in Pwllheli different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Can you visit Pwllheli 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.
Do you charge extra to travel to Pwllheli?
Not normally. Our guide prices include normal travel to Pwllheli. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
