Duraseal® warm-edge spacer

Duraseal® is a warm-edge spacer system ideal for high-volume production of dual- and triple-pane insulating glass.

Duraseal is preassembled with proven components, sealant, spacers and desiccant to create a high-performance system. Other features:
  • Composite laminating technology
  • Lower conductivity polymeric construction
  • Black or gray sightline
  • Proven adhesive technology
  • Optimized packaging
  • Sizes to accommodate airspaces of ¼” (6mm) to 13/16” (20.5mm)
Duraseal requires heat and minimal compression for efficient handling and production. Other benefits:
  • Smooth surface appearance
  • Superior argon gas retention
  • Improved condensation resistance
