Single-pane leaded glass has a traditional, purist look, but triple-insulating offers the bonus benefits of increased energy efficiency, security, noise reduction, and easier cleaning. Insulating can also help with Title 24 requirements in a new-build home.

Both new and existing art glass can be insulated, whether it was created by us or not. Often times it makes sense to insulate repaired art glass to prevent further damage from age, accident or weather. 

It is also important to note that your wood stops (the trim pieces around the glass) should have a face-width of at least 5/8” to conceal the insulating materials (urethane, spacer and silver mylar strip) around the perimeter of the glass, and still give wiggle room for the insulated glass unit’s installation.

Triple insulating is essentially a dual-pane window with leaded glass between two pieces of tempered glass. We sandwich and seal the single-pane leaded glass panel between 2 pieces of clear tempered glass using foam desiccant spacers and urethane to create a single insulated unit, all of which is done in-house.

See photos below - you may notice a glare off the tempered glass, more so when viewing your stained glass from the exterior, but you typically cannot tell a visual difference when looking through the glass from the interior.

These insulated units are typically 3/4" thick, but can vary from minimum 5/8″ thick to 1″ thick (or thicker) depending on the installation specifications. It’s important to ensure that your window/door can accommodate this thickness.

Pricing for insulation is sq-ft-based and includes the cost of the tempered glass, the insulating materials, and the labor to build the units. It will extend your project's lead time by a week or more, depending on the weather. (If it is raining or has recently rained, we cannot insulate because moisture will get locked inside the panel.)
