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.

Questions about rafter insulation in Brecon
Do you cover all of LD3?
Yes, we cover the LD3 postcode district and the districts around Brecon.
Can a landlord in Brecon book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you take on jobs outside Brecon?
Yes. We also work in Builth Wells and Ystradgynlais and elsewhere in Powys.
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.
