The figures shown above are for guide purposes only. Slight variations may occur due to glass specification, time of year, manufacturing tolerance, point of manufacture and type of instrumentation used.


Visible Light Transmittance: This is the percentage of visible light directly transmitted through the glass.

Solar Factor: This is the percentage of total solar energy (or heat from the sun) able to pass through the glass.

U-Value: This is used to measure internal heat loss during cooler periods. The lower the number, the greater the insulation.

UV Transmission: Sun damaging UV rays are dramatically reduced, allowing greater protection of your furniture and fabrics.
