All Year Round Glazing - Technical Data

The information below gives you a clearer idea of the impressive performance of Celsius, Celsius Clear and Celsius Plus when compared to standard glass or polycarbonate.

Visible Light Transmittance

This is the percentage of visable 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.
