Energy efficient glass with solar control and low emissivity for facades and windows.

Jump to:
+44 (0)1788 535353 www.agc-yourglass.com


Suitable for use in double and triple glazed units for curtainwall facades and windows. Particularly well suited to tertiary buildings.


High-performance solar-control glazing range with thermal insulation. The solar control function is achieved by applying a selective metal coating.

Glazing for windows and curtainwall facades providing both solar control and thermal insulations functions. These high performance coated glass types offer a range of Light Transmission, Solar Factor (g-value) and U value depending on your project requirements. Available in different safety glass options including toughened glass, heat-strengthened glass and laminated glass.

Features and benefits:

  • High light transmission, low solar heat throughput.
  • Stopray solar-control glazing with thermal insulation is suitable for all climates: combines solar control in summer with thermal insulation in winter.
  • Various colours, including an extraordinary neutral, low light-reflection range.
  • Always in double glazed units. Monolithic glass available to processors.
  • Selectivity (relationship between LT and SF = maximum 2): Excellent for the range of neutral colours.
  • Assists in keeping energy costs to a minimum.
  • Wide range of light reflection and light transmission levels.
  • Different colours, extensive range of neutral colours.
  • Available in different safety glass options including toughened glass, heat-strengthened glass and laminated glass.
