Duralite® warm-edge spacer

Ideal for high-volume production of dual- and triple-pane insulating glass units, Duralite® is a patented warm-edge spacer system that is applied in a single step using heat and minimal compression.

Duralite is preassembled with proven components, sealant, spacer and desiccant to create a high-performance system. Other features:
  • Composite laminating technology
  • Polycarbonate spacer element (no metal)
  • Black or gray sightline
  • Proven adhesive technology
  • Optimized packaging
  • Sizes to accommodate airspaces of ¼” (6mm) to 13/16” (20.5mm)
Duralite requires minimal compression for efficient handling and production. Other benefits:
  • Smooth surface appearance
  • Superior argon gas retention
  • Improved condensation resistance
  • Warmer edge of glass temperature
