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
- Vapour control layer where the design needs one

Questions about rafter insulation in Darwen
Will I get a written quote for work in Darwen?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you take on jobs outside Darwen?
Yes. We also work in Blackburn and Haslingden and elsewhere in Lancashire.
Can you visit Darwen outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
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.
