At Cristal Windows, we combine timeless elegance with modern performance. Our uPVC leaded windows and Georgian leaded windows bring the beauty of traditional window design into the 21st century, offering exceptional style and energy efficiency.

Whether you’re renovating a period property or adding character to a newer home, our decorative glazing options help create a look that’s both classic and practical.

What Is Leaded Glass?

Leaded glass refers to decorative window glass featuring lead strips (called cames or self-adhesive lead) arranged in patterns like diamond, square, or custom designs. Historically used in heritage buildings, it remains a popular choice today for adding charm and visual interest.

At Cristal Windows, we use modern self-adhesive lead on sealed double-glazed and triple-glazed units. You can choose from a range of lead widths (4mm, 6mm, 9mm, and 12mm) and finishes including:

  • Silver
  • Aged effect (for that antique look)
  • Black
  • Gold

We also offer flat or oval profiles and optional soldered joints for a traditional, handcrafted appearance.

What Are Georgian Bar Windows?

Georgian windows mimic the grid-style appearance of historic Georgian-era sash windows, traditionally made from multiple small panes. Today, our Georgian bar systems replicate this look within a single, thermally efficient double-glazed and triple-glazed unit.

Options include:

  • Internal bars between the glass for a low-maintenance finish
  • External astragal bars that sit on the surface of the glass for greater authenticity
  • Custom patterns to suit your window sizes and architectural style
