SunGuard Solar

Gold 20

SunGuard Solar Gold 20 provides a light transmission of 18% which reduces glare, it also utilises a low solar factor of 16% to reduce demands on air conditioning and help control the temperature inside the building. To provide complete performance we have recommended ClimaGuard 1.0 on the inner pane (surface 3) to provide U value performance of 1.0 W/m2K. The surface of the glass is also quite reflective providing privacy for the building occupants.
