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.
- Insulated plasterboard lining where specified
- Vapour control layer where the design needs one

Questions about rafter insulation in Mitcham
Will I get a written quote for work in Mitcham?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Can a landlord in Mitcham 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 Mitcham?
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.
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.
Can I use the loft as a bedroom after rafter insulation?
Insulation alone does not make a loft habitable. Fire escape, stairs, floor strength and headroom all come into a conversion, which needs building control.
