Guardian Glass has updated its residential insulating glass products.

Its warm-edge spacer manufactured in its Sun Prairie, Wisconsin fabrication facility is now branded Guardian Align.

Guardian has changed the colour of its primary polyisobutyl sealant to black in order to create cleaner looking sightlines that seamlessly blends in with more modern and contemporary window frames.

Failed insulated units lead to expensive warranty repairs and brand destruction.

Therefore, Guardian has designed IGUs using Guardian Align spacers to have a robust seal that provides high argon retention rates and low seal failures to ensure customers can focus on making and selling windows, not replacing them.

The Align spacers feature:

  • Ultra-thin, low conductivity corrugated stainless steel construction
  • 90° corners with a hermetic 4th corner joint
  • High-strength, low-conductivity PIB primary sealant with extra-long diffusion path
  • High-modulus, commercial-grade silicone secondary sealant
  • 20-year warranty

“Guardian Align spacers are extremely durable with impressive thermal insulation performance,” said Scott Billings, Vice President and General Manager, Glass Fabrication, Guardian Glass North America.
