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.

Questions about rafter insulation in St Austell
Can a landlord in St Austell book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Not normally. Our guide prices include normal travel to St Austell. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
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.
