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.

Questions about rafter insulation in West Sussex

How do I book a survey in West Sussex?

Send the form or call us. We call back to agree a time and confirm it in writing.

Are your prices the same across West Sussex?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

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.
