Victorian and Edwardian terraces: a gentle approach to an old loft

Old terraces have narrow lofts, solid brick party walls and timbers that like to stay dry. Breathable insulation and good airflow suit them well.

What makes these lofts different

Victorian and Edwardian roofs are often slate over timber, with solid brick party walls either side and a chimney breast rising through the middle. Many have had little done since they were built, or a thin layer added decades ago.

A material that breathes

Older houses manage moisture differently from modern ones. Sheep’s wool, which takes up and gives back moisture, is a comfortable fit, though mineral wool works too when the loft is well ventilated. Either way it goes on the floor, between and over the joists.

Things we check

Gaps in the party wall where air and sound pass through, old cables that need lifting clear, and whether the roof has enough airflow once the loft is insulated.

Common questions

Is sheep’s wool best for a Victorian house?

It’s a good fit because it handles moisture well, but mineral wool also works in a well-ventilated loft. We’ll explain the choice.

My loft is very narrow. Can it still be insulated?

Yes. Narrow lofts are often quick to do.

Do I need to worry about the party wall?

We check it for gaps. Sealing them helps with draughts and, sometimes, noise.
