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.
- Build-up designed for your type of roof underlay
- Vapour control layer where the design needs one
- Rigid insulation between the rafters, joints taped

Questions about rafter insulation in Sheffield
What do I need to do before you arrive in Sheffield?
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 Sheffield?
Not normally. Our guide prices include normal travel to Sheffield. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Do you cover all of S1?
Yes, we cover the S1 postcode district and the districts around Sheffield.
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.
