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 Blackwood
Is loft work in Blackwood 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.
Do you charge extra to travel to Blackwood?
Not normally. Our guide prices include normal travel to Blackwood. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
How do I pay for work in Blackwood?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
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.
