Patent glazing
A practical system with a long architectural history.
Patent glazing has played an important role in British architecture since the Victorian era, when advances in glass manufacturing and metal glazing systems enabled the construction of expansive glazed roofs, railway stations, factories, markets and public buildings.
Traditional patent glazing systems became synonymous with the elegant glazed structures of the 19th and early 20th centuries, providing natural daylight while maintaining the distinctive architectural character of historic buildings.
Established in 1946, Lonsdale Metal Company has become a recognised British manufacturer of specialist patent glazing and roof glazing systems, combining traditional glazing principles with modern materials and performance requirements.
Rooflights & Atriums works closely with Lonsdale Metal Company, using its specialist glazing systems to deliver both heritage patent glazing restoration and contemporary roof glazing installations.
Our experience in patent glazing replacement, heritage rooflight refurbishment and bespoke glazed roof construction enables us to preserve the character of historic structures while incorporating modern glazing technology, improved weather resistance and appropriate thermal performance.
