Enabling architects, builders, and glaziers to meet stringent energy codes while maintaining familiar installation methods, Oldcastle BuildingEnvelope, Inc.(OBE) is expanding its portfolio with thin triple insulating glass (IGU) options for select curtain wall and storefronts. With no added frame depth or weight compared to traditional double-glazed systems and a 25-percent improvement in energy efficiency, this advancement opens new design opportunities for high performance facades. This thin triple glass option provides enhanced design flexibility, reliable performance, and a clean, modern aesthetic.

Engineered for International Energy Conservation Code (IECC) Climate Zones 3-8, where increasingly stringent U-factor requirements and stretch codes are driving demand, these IGUs are designed to meet a wide range of performance requirements for projects that demand maximum thermal efficiency, including education, healthcare, commercial offices, multifamily dwellings, retail, and government facilities.

Thin triple insulating glass units require no framing changes, fitting seamlessly into select curtain wall and storefront systems. Glazing systems with thin triple glass also maintain the same fabrication and installation methods of double-glazed systems. With OBE as a single-source partner for both framing systems and glass, the path from specification to installation is streamlined.

Thin triple glass is now available as an option across several trusted OBE systems, delivering industry-leading thermal efficiency:
