Doubling Thermal Efficiency
at Windows
GreenGirt XO is a structural support system providing a thermal break by bringing windows into alignment with the thermal plane of the continuous insulation. Windows and openings play a significant role in the overall efficiency of a building envelope. The GreenGirt XO continuous insulation system for windows addresses the decade-old issue of significant thermal loss at openings by eliminating through-wall metal, through-insulation fasteners, conductive metal angles, and inefficient wood-blocking.

The Problem: Thermal Efficiency Loss at Windows
Legacy materials such as metal angles and wood blocks prevent the thermal plane of the window from lining up with the continuous insulation, resulting in up to 40% or more energy loss for the opening.
The Solution: GreenGirt XO
GreenGirt XO is a composite metal hybrid (CMH) transition structural framing for windows and openings, bringing the thermal plane of the window in line with the continuous insulation, and maximizing the thermal efficiency to more than 90% for the opening.
How It Works
GreenGirt XO can more than double the R-value of a window opening by aligning the thermal plane of the window with the continuous insulation system, eliminating thermal transfer at the window framing. GreenGirt XO provides a structural support system that eliminates the need for through-wall metal or through-insulation fasteners.
