GreenGirt CMH™ Continuous Insulation Systems

A family of continuous insulation systems that combines structural composite metal hybrid sub-framing and compatible accessories with expert engineering support. GreenGirt CMH systems can be used with mineral wool, spray foam, or your preferred insulation material to eliminate thermal bridging and increase energy efficiency.

GreenGirt Max CMH™

GreenGirt Max CMH™ is a continuous insulation system that combines structural composite metal hybrid Z-girts, compatible accessories, and expert engineering, featuring 0.20″ steel-reinforced flanges.

GreenGirt CMH Delta™ Adjustable

GreenGirt CMH Delta™ is an adjustable continuous insulation system that combines structural composite metal hybrid sub-framing and compatible accessories with expert engineering support.

Classification of Continuous Insulation Z-Girts

Continuous insulation Z-girts are categorized into three distinct classes based on their ability to meet key performance criteria. These criteria include structural capacity, structural performance, thermal efficiency, fire resistance, and the durability of connections over the building’s lifecycle. Each class represents a different level of performance, allowing designers, contractors, and installers to select the most suitable system for their project’s specific demands and requirements.
