Knowles Stained Glassworks are experts in the encapsulation process.

Encapsulated real leaded light panels into sealed units. For over 15 years here at Knowles we have been offering the service to encapsulate and seal existing or new bespoke stained glass coloured real leaded light windows and panels into sealed units creating a triple glazed unit.

At Knowles Stained Glass Work we pride ourselves in retaining and restoring original stained glass and can seal old leaded lights into toughened sealed units. Alternatively we can design and create new bespoke designs. This method will ensure the original leaded lights are reused and retain the providence of our English Heritage. This process is particularly good if installing new UPVC, Aluminium and timber windows as well as extending some existing metal frames, old style crittal frames and timber frames.

We can Encapsulate original stained glass, squares and diamonds and we can create new bespoke designs. This process offers the home owner. Better insulation, security and protection of their stained glass panels. Once the original leaded light has been removed we will temporary glaze the opening. The leaded light panel is taken to our workshop, where our skilled glaziers will take a rubbing of each panel to ensure all pieces of glass are replaced exactly in the same design as before. For squares and diamonds all glass is measured and laid out in the same pattern. Once the panel is carefully taken apart, the glass is cleaned, all old cement carefully removed and any breakages replaced with as close matching glass, both colour and texture as original.

If required we can also repaint any painted stained glass pieces that are badly broken or alternatively to retain the providence of the old glass we glue the pieces together. A crack is better than losing the entire piece of glass. The glass then is re leaded using the same gauge thickness of lead as was used by the original glaziers. Once leaded we then solder both sides and then the panels are cemented, cleaned and polished. We allow a minimum of 2 weeks for the panels to completely dry before sealing between two pieces of toughened glass and two spacer bars. This will make a 22mm minimum thickness sealed unit, creating a triple glazed unit with three layers of glass.
