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 Warminster
Will I get a written quote for work in Warminster?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Can a landlord in Warminster book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Is insulating between the rafters better than the loft floor?
Not for saving energy alone. Insulating the floor heats less space and costs far less. Rafter insulation is the right answer when the loft itself needs to be warm.
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.
