Super Spacer® Cushion Edge™

Protection and performance for delicate glass and triple-glazed units

Super Spacer® Cushion Edge is a specialized solution designed to protect delicate glass in insulating glass units, including decorative applications like stained glass windows and center-lites. Its flexible, U-shaped silicone design cushions and stabilizes glass, while maintaining the performance expected from a warm-edge spacer system.

Best for:

  • Triple-glazed insulating glass units
  • Center-lite and decorative (art) glass applications
  • Systems requiring added protection against glass-to-glass contact

Super Spacer® Cushion Edge™ is purpose-built for applications where glass protection and multi-lite performance are critical. It is especially effective in triple-glazed window and door systems, as well as in decorative and art glass units with center lites, including stained glass windows. It is also well-suited for specialty residential window designs and insulating glass units that require added internal stability and cushioning.
