Windsor Glazing System utilizes Super Space and Cardinal glass.

Windsor Glazing System

Windsor’s Glazing System leverages the energy performance of the SuperSpacerTM Warm Edge Technology along with Cardinal LoE coated panes and sheet glass, to create one of the most thermally-efficient IG solutions on the market.

When the size or composition of an IG unit falls outside of our current production capabilities, Windsor will utilize Cardinal IG. Some of the products that require Cardinal IG include Tinted, Obscure, Laminated and Insulated Glass over 30 ft2.

The Windsor Glazing System will also utilize the Double Strength (DS) glass as standard for all Windsor products: Pinnacle, Legend and Next Dimension. In instances where Windsor or Cardinal previously used single strength glass, we will now use double strength glass. Double Strength (DS) glass is 50% thicker than Single Strength (SS) glass, further improving thermal performance properties.
