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 County Down
Do you cover the whole of County Down?
Yes. We cover every town and village in County Down, including Bangor (County Down), Newtownards and Newry.
Which council covers my address in County Down?
Councils in County Down include Ards and North Down, Armagh City, Banbridge and Craigavon, Lisburn and Castlereagh and Newry, Mourne and Down. Your council matters for building control questions and some funding schemes.
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.
