Duralite™ Reduces Heat Transfer

Duralite™ Warm-Edge Insulated Glass Spacer

Industry Leading Warm-Edge Insulated Glass Spacer System

Sun uses Duralite™ in all of our IG units. Duralite™ is an industry-leading insulated glass spacer system that provides the best thermal performance in the industry. Its structure uses Composite laminating technology, while its flexible properties ensure a superior glass seal and the highest Argon gas retention in the industry. Duralite™ has a smooth visible surface appearance. It is impermeable to gas and water vapor and has proven adhesive technology to ensure a long-lasting glass seal. Duralite™ has the lowest conductivity of any warm-edge spacer. It provides a warmer edge-of-glass temperature which improves the condensation resistance of the IG unit.

The spacer is applied in a single, continuous path following the perimeter of the glass, which is important primarily because it results in a single corner seam. The other three corners are formed as bends in the spacer with no joint or seam. This single corner seam helps give our insulated glass units an excellent hermetic seal and superior Argon gas retention. Most other glass spacer systems require each corner to be mechanically joined and sealed.
