Super Spacer® Premium Plus

Quanex’s Super Spacer® Premium Plus has been the industry standard for insulating glass (IG) light commercial door units for decades, and its performance is still second to none.

This high-quality, silicone warm-edge spacer is extruded with a built-in desiccant, which helps it keep moisture out and argon gas in. Its flexible design, along with a vapor barrier and secondary sealant, makes this possible.

With its sleek 1/4″ sightline, Super Spacer Premium Plus delivers a modern, clean look without sacrificing performance. First introduced over 30 years ago, Super Spacer technology revolutionized the IG industry and continues to be a leader in a wide range of critical applications. Consider Super Spacer Premium Plus to take your commercial door units to the next level.
