Leaded Windows &

Steel Window Restoration

Leaded windows / leaded lights - explained

Leaded lights, leaded windows or leadlights are the generic names for small panes of glass that are held together or supported by lead “cames”. The lead cames are basically long lengths of lead, usually 9mm or 12mm wide (approx. 1/2 inch) that have an H-shaped cross section designed to carry the small panes of glass either side.

The pieces of glass used in leaded lights are nearly always either diamond shaped or square (rectangular) and these simple geometric shapes give rise to their authentic name which is “quarries”. These are held in the lead framework with leaded light cement and soldering on every joint.

Opposite are pictures of the lead came H-section and leaded lights being constructed in our workshop prior to soldering and cementing. To understand the full process of how leaded lights are made please see making a traditional leaded light.

Unlike leaded lights stained glass windows are traditionally far more elaborate and pictorial, often depicting crests or images that are pertinent to the building or area. Because the traditional technique for putting a leaded light together is the same as a stained glass panel we can service both product areas in-house.

We also offer a stained glass design service should there be a special occasion or need to create a panel from scratch. Most of our work in this area however is focussed on conservation or restoration - typically ecclesiastical, national trust or listed and older property.

Traditional leaded lights are very much part of our Heritage and date back many hundreds of years, hence why we are proud to be involved in conserving and restoring these important architectural elements.

Tec Glass have over 25 years experience in the manufacture and repair of leaded and stained glass windows, with a workshop in Thame, Oxfordshire. We work on projects large and small, varying from on-site lead window repairs through to brand new supply of steel casements or timber windows with leaded lights. Being an independent specialist glazier we can also advise and help with any other glazing requirements, which are detailed in the Products Section of this site.

If your property is a listed building or there are special requirements to be met when replacing or updating traditional windows it is usually best to discuss with both the local planning office as well as a traditional glazier such as Tec Glass.
