Frequently Asked Questions (FAQs)
What are GreenGirt CMH Clips™, and what do they do?
GreenGirt CMH Clips™ are a continuous insulation clip-and-rail system built from composite metal hybrid material with a steel-reinforced flange, delivering zero thermal bridging while providing secure cladding attachment. They install vertically, with hat channel spanning across the clips to create the cladding attachment plane, and are compatible with mineral wool or spray foam insulation depending on the project.
How do GreenGirt CMH Clips eliminate thermal bridging vs. metal Z-girts / through-insulation fasteners?
GreenGirt CMH Clips eliminate common thermal-bridge pathways by removing the need for through-wall metal and through-insulation fasteners commonly found in legacy systems. The system’s composite metal hybrid approach is positioned as a complete thermal break, helping prevent thermal bridging and related moisture issues.
What are the key configuration options for GreenGirt CMH Clips (available depths/sizes and compatibility with insulation, substrates, and cladding)?
Key configurations for GreenGirt CMH Clips include custom depths from 1.5″ to 6″ (with multiple increments listed), vertical orientation with horizontal hat channels, and compatibility with mineral wool or spray foam. GreenGirt CMH Clips are compatible with CMU and closed framing substrates, are 6″ long, compatible with all cladding types, and has a drainage plane behind the system.
Are GreenGirt CMH Clips™ available in stainless steel?
Yes. The steel-reinforced flanges on GreenGirt CMH Clips are available in stainless steel for coastal, high-humidity, or otherwise corrosive environments, in addition to standard galvanized steel.
Is GreenGirt CMH Clips™ a clip-and-rail system?
Yes. GreenGirt CMH Clips is a clip-and-rail system: the clips attach to the structure, and hat channel spans across them to create the cladding attachment plane. The difference is what the rail is made of. GreenGirt CMH Clips uses standard hat channel rather than a proprietary rail profile, so there’s no dependency on a single supplier’s rail shape or sourcing, while still eliminating the need for full 8-foot Z-girts and delivering 98-99% R-value efficiency through the composite metal hybrid clip design.
What cladding and substrates are GreenGirt CMH Clips™ compatible with?
GreenGirt CMH Clips are designed to work with any cladding material and weight your project requires, including ACM, fiber cement, metal panel, high-pressure laminate, stucco, thin brick, terracotta, natural stone, GFRC, wood, and copper. On the substrate side, it’s compatible with CMU, masonry, or metal or wood studs with sheathing.
What insulation types and thicknesses work with GreenGirt CMH Clips™?
GreenGirt CMH Clips is compatible with mineral wool or spray foam insulation, in thicknesses from 1.5″ to 6″.
