Greater Energy Efficiency Possible with Launch of Innovative Storefront Systems from Oldcastle BuildingEnvelope

DALLAS – (June 4, 2025) – Oldcastle BuildingEnvelope, Inc. (“OBE”), a leading global supplier of architectural glass, metal, and hardware, announced today the launch of its advanced thermal storefront systems, now engineered for today’s stringent energy demands. The Series 3000 XT and 6000 XT High Performance Storefront systems feature thin triple insulating glass units (IGUs) and deliver industry-leading U-factors as low as 0.20, setting a new standard for thermal performance.

These next-generation systems incorporate thin triple IGUs to deliver up to 25% better thermal performance than traditional double-glazed storefront systems, all without increasing system depth. Engineered to meet IECC Climate Zones 3 through 8, with a focus on regions like the Northeast and Northwest where higher performance standards and stretch codes are driving demand, these high-performance versions of OBE’s trusted Series 3000 XT and 6000 XT Storefront systems feature dual pour and debridge thermal break, optimizing both thermal performance and condensation resistance.

The launch of these High Thermal Storefront systems featuring thin triple IGUs is an additional glazing option for OBE’s Series 3000 XT and 6000 XT, designed to meet a wide range of performance requirements. The standard 1” insulating glass configuration still provides enhanced energy efficiency, offering a practical balance between performance and cost-effectiveness. For projects that demand maximum thermal performance, the 1” thin triple IGU option pushes efficiency even further – without requiring changes to system depth or installation methods. Both configurations integrate seamlessly, supporting design flexibility, reliable performance, and a clean, modern aesthetic.

The Series 3000 XT and 6000 XT High Performance Storefront systems are a smarter way to build. By sourcing both glass and framing from a single, trusted partner, project coordination is streamlined, reducing delays and ensuring a seamless fit from specification to installation. Designed for efficiency at every stage, this system delivers the thermal performance, design flexibility, and ease of installation needed to meet today’s energy codes – without added complexity
