GreenGirt CMH XO is a composite metal hybrid sub-framing system that provides necessary support and thermal breaks by bringing windows into alignment with the thermal plane of a building’s continuous insulation. It addresses the thermal loss of up to 50+% at window openings by eliminating through-wall metal, through-insulation fasteners, conductive metal angles, and inefficient wood-blocking and achieves a 96+% thermal efficiency at window openings, more than doubling R-value efficiency.
This product is a 2024 Product Innovation Award winner.
Judge’s Comment: “By utilizing a composite material that integrates structural support with thermal efficiency, this solution helps to minimize thermal bridging and improve overall energy performance. Its lightweight design simplifies installation, making it a practical choice for both new constructions and retrofits.”
