What is a U-Value?

This measures how effectively a glass unit prevents indoor heat from escaping. The lower the U-value number, the better insulated the property will be, keeping heating costs down during cold British winters.

What is Solar Heat Reflection?

The percentage of the sun's infrared heat energy that is bounced away before it can enter the room. Choosing a high percentage prevents the uncomfortable "greenhouse effect" during hot summer months.

What is Light Transmission?
The percentage of visible natural light that passes completely through the glazing. Higher numbers translate to a brighter, more naturally illuminated living area.
