Duraseal® Warm-Edge Spacer

Duraseal® is a warm-edge spacer system ideal for high-volume production of dual- and triple-pane insulating glass. It has demonstrated proven performance for many years, and as a preassembled solution combining spacer, sealant and desiccant, it’s a high-performance window spacer system that you can count on for more efficient production and customer satisfaction.

Duraseal glass spacers require heat and minimal compression for efficient handling and production and are compatible with modern manufacturing equipment to take your production to the next level.
