Passiv Glas Vacuum Glazing

Thinner, Warmer, Quieter, Better.

Bringing innovation and comfort together. Vacuum glazing is a revolutionary step toward lower energy bills and achieving Passive House standards.

At GK Joinery, we’re proud to offer PassivGlas™ – a next-generation vacuum-insulated glazing solution that delivers outstanding thermal and acoustic performance in an ultra-slim design.

Whether you're upgrading a period home or building something brand new, PassivGlas™ helps you achieve modern energy efficiency without compromising on appearance or character.

Why choose vacuum glazing?

  • Unmatched insulation
    PassivGlas™ offers incredibly low U-values, helping to keep homes warmer in winter and cooler in summer – without the bulk of triple glazing.
  • Peace and quiet, built in
    Its advanced construction significantly reduces external noise, making it ideal for homes in busy or urban areas.
  • Slimline, lightweight design
    At just over 6mm thick, PassivGlas™ can often be fitted into existing window frames – ideal for retrofits and sensitive conservation areas.
  • Long-lasting performance
    Thanks to toughened glass and a strong vacuum seal, these units are built to last and keep performing year after year.
  • Eco-conscious choice
    Lower energy use means lower bills and a reduced carbon footprint – all while maintaining a comfortable home environment.

Perfect for heritage and contemporary homes

Whether you're looking to preserve traditional timber windows or enhance a new build with cutting-edge performance, PassivGlas™ offers flexibility and finesse. It's particularly well-suited to listed buildings, conservation areas, and projects where both efficiency and aesthetics matter.
