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

Questions about rafter insulation in Streatham
What do I need to do before you arrive in Streatham?
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 Streatham?
Not normally. Our guide prices include normal travel to Streatham. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Do you cover all of SW16?
Yes, we cover the SW16 postcode district and the districts around Streatham.
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.
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.
