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.
- 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 Portishead
Can a landlord in Portishead book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
What do I need to do before you arrive in Portishead?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Do you charge extra to travel to Portishead?
Not normally. Our guide prices include normal travel to Portishead. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
