GreenGirt XO™

GreenGirt XO™ is a structural thermal framing system for all windows and openings. Proudly made in the USA by Advanced Architectural Products, GreenGirt XO effectively tackles the critical challenge of thermal loss at building openings by eliminating through-wall metal, through-insulation fasteners, conductive metal angles, and inefficient wood-blocking. By aligning the thermal plane of the window with the thermal plane of the insulation, the overall efficiency of the building envelope is enhanced by the GreenGirt XO system, achieving up to 97% thermal efficiency and more than doubling the effective R-value when compared to legacy systems. Supported by expert engineering, this system seamlessly integrates into the building's facade, providing a sophisticated and efficient solution to optimize window and opening performance. Engineered with true flexibility in mind, GreenGirt XO accommodates a wide range of window types and sizes. Its modular design allows customization to project-specific requirements. The system includes composite fiberglass headers, sills (with or without integrated rails), and jambs; aluminum and galvanized dead load clips; header angles; header, jamb, and sill aluminum flange inserts (available in standard and spacer variants); and self-sealing anchor plates, all customized to your project in collaboration with the A2P engineering team.

The GreenGirt XO System adheres to the eight continuous insulation best practices. Additional features that make the GreenGirt XO System stand out as the best choice for your building include:

Doubling Thermal Efficiency at Windows
GreenGirt XO aligns the thermal plane of the window with the thermal plane of the insulation for enhanced energy performance—meeting the window alignment requirements in ASHRAE 90.1-2022.

Designed for Versatile Opening and Insulation Options
GreenGirt XO is flexible to meet the needs of any building opening, including punched openings, storefronts, curtain walls, and ribbon windows, to ensure seamless integrations and superior performance. Also designed to work with any type of insulation.

Eliminates Metal Angles and Wood Blocking
Revolutionize your build by replacing traditional metal angles and wood blocking with innovative composite metal hybrid materials for a more efficient and sustainable construction approach.

Resistant to Creep and Fatigue
Engineered with advanced composite metal hybrid materials, GreenGirt XO prevents fastener creep, resists fatigue and ensures lasting structural integrity.

Committed to Sustainable Design
By increasing energy efficiency at building openings, GreenGirt XO reduces energy waste, conserving resources and reducing embodied carbon emissions. To ensure full transparency, GreenGirt XO is complete with a Declare label, an EPD, and uses Red-List free materials.
