With The Heritage Window Company, retain the unique look of your steel windows with aluminium double glazing from The Heritage Window Company.
Our unique Benenden window is the slimmest aluminium window available on the market, designed to replace Crittall windows or as a bespoke window for new build projects. The Benenden fits perfectly into your original timber frames, or direct to brick or stone, providing all the benefits of modern double glazing whilst maintaining the period character of your home.
Please note: The Period Metal Window Company is no longer associated with The Heritage Window Company.
"We wanted Crittall window replacements because our originals were rusting and draughty, and we have been thrilled by how closely the double glazed Heritage Window Company windows match the original Crittall windows that we had."
