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.
- Rigid insulation between the rafters, joints taped
- Build-up designed for your type of roof underlay
- Insulated plasterboard lining where specified

Questions about rafter insulation in Swanley
Do you charge extra to travel to Swanley?
Not normally. Our guide prices include normal travel to Swanley. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Do you cover all of BR8?
Yes, we cover the BR8 postcode district and the districts around Swanley.
Can a landlord in Swanley book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
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.
