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.

Questions about rafter insulation in Winchester

Can you visit Winchester 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.

Do you take on jobs outside Winchester?

Yes. We also work in Eastleigh and Romsey and elsewhere in Hampshire.

Is loft work in Winchester 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.

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.

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.
