Glazing Method

All Sun products are glazed with Dual Glazed insulated glass. Our Casement family products as well as our Fixed Lite products are also available with Triple Glazed insulated glass.

Duralite

Duralite™ Warm-Edge Spacer System

All Sun insulated glass units use the Duralite™ warm-edge glass spacer system. Duralite is the only all non-metallic spacer system available. This gives superior thermal performance and its flexible properties provide a superior seal and excellent argon retention. It is one of the reasons we are able to provide a full 20 year warranty on our insulated glass.

Low-E Insulated Glass

Most building codes now require thermally efficient insulated glass in windows and doors. Therefore, high-performance Low-E glass has become an industry standard. Sun offers a range of Low-E Insulated Glass units to match maximum thermal benefits with your region.

• Sun Advantage 270 is for regions that have both heating and cooling seasons.
• Sun Advantage 366 is for regions that require mostly cooling.
• Sun Advantage 270 plus adds a 4th surface i89 Low-E to lower the U-value and improve thermal performance.
• Sun Advantage 366 plus adds a 4th surface i89 Low-E to lower the U-value and improve thermal performance.
• Clear glass is available for specific applications where energy performance codes do not apply or thermal performance is not a concern.
