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

Questions about rafter insulation in Melksham

Is loft work in Melksham different from anywhere else?

The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.

Do you take on jobs outside Melksham?

Yes. We also work in Trowbridge (Wiltshire) and Chippenham and elsewhere in Wiltshire.

Can a landlord in Melksham book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

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.
