Performance Glass

At the forefront of performance driven glass to enhance sustainability, Glassworks are proud to have a range of the most advanced energy saving glass products with proven performance figures that are second-to-none.

Here are some figures you’ll be benchmarking and what they mean:
Visible Light Transmission (VLT): measures the percentage of natural light entering a room and visibility from the inside out
U-Value: measures how much heat is transferred through the glass. The lower the U-Value the better the insulation properties.
Solar Heat Gain Coefficient: measures how much solar radiation passes through the glass. The lower the SHGC the greater the thermal stopping power.
