Storefront Fabrication

Built for long-term durability and thermal resilience, the Series 6000XT storefront features a dual pour and debridge thermal break, enhancing both energy efficiency and condensation resistance. Its center-set glazing configuration provides structural stability and design versatility, while a screw spline assembly ensures precise fabrication and ease of installation. The high-performance sill receptor requires no additional anchoring at the sill member, simplifying the process while maintaining strength. With 90° corner mullions and the option for Red List Free materials, the Series 6000XT meets the highest standards for sustainability, efficiency, and architectural flexibility.

Glass Fabrication

The Series 6000XT accommodates two glazing options to align with a wide range of performance requirements. The 1” insulating glass configuration provides enhanced energy efficiency, delivering a balance between performance and cost-effectiveness. For projects requiring maximum thermal performance, the 1” thin triple insulating glass unit option pushes efficiency even further - achieving next-generation energy savings without increasing system depth. Both configurations integrate seamlessly, ensuring exceptional performance, a modern aesthetic, and long-term reliability.

Seamless Integration, Maximum Efficiency

The Series 6000XT storefront is more than a high-performance system – it’s a smarter way to build. By sourcing both glass and framing from a single, trusted partner, the Series 6000XT storefront streamlines the entire process - ensuring precision, quality, and seamless compatibility from start to finish. With fewer coordination challenges and a fully integrated approach, this system simplifies specifications and delivers exceptional thermal performance without added complexity.
