Pyroglass Pyranova® is a specialised multi-laminated glass with fire resistant interlayers that foam up in the event of fire, adding the ability to also block radiant heat. As a single glazed Laminate, this Insulating Fire Rated Glass performs up to FRL -/60/60.

If more advanced Insulating performance is required, up to FRL -/120/120, see our Pyroglass ISO Pyranova®.

With clear interlayers and using clear glass, high Clarity allows a clean view through the glass and high Visible Light Transmittance (VLT) that optimises natural light entering inside and filling your space. For all internal applications, use 23mm thick. For all external applications use 27mm thick.

Pyroglass Pyranova® is also:

  • Safe – Grade A Safety – certified to AS/NZS 2208
  • Secure – Strong against breakage and penetration
  • Quiet – Advanced acoustic performance compared to regular float glass
  • Protects – Over 99% UV protection to reduce colour fading factors

Note: Pyroglass Pyranova® is not tested as a standalone product. It is tested as a complete fire rated system including frame. Contact us for full system options.

Pyranova® is a trade mark of Schott AG.
