Super Spacer® TriSeal™

A complete commercial IG spacer system for long-term performance

Super Spacer^® TriSeal^™ is Quanex’s most advanced warm-edge solution, a fully integrated commercial IG spacer system engineered with a true triple-seal design. With pre-applied PIB and delivered on manual reels, it provides consistent, high-performance sealing for manufacturers operating manual or semi-automated insulating glass lines.

Best for:

High-performance commercial glazing systems
Manual or semi-automated IG production environments
Projects with extreme environmental exposure
Applications requiring maximum seal integrity

Super Spacer^® TriSeal™ is engineered for insulating glass applications where both manual fabrication and long-term performance are critical. As a commercial IG spacer system, it performs especially well in manual or semi-automated insulating glass production environments, as well as in commercial curtainwall and façade systems. It is an excellent fit for high-rise and large-scale architectural projects, including healthcare, education, and other institutional buildings, and is particularly well suited for structures in extreme climates or high-humidity environments.

Why Choose Super Spacer^® TriSeal^™
