GreenGirt Composite Metal Hybrid (CMH) is an innovative building material designed for real-world applications and boasts the highest efficiency possible with an industry-leading R-value per strength ratio. This strong profile allows for real-life, on-center spacing of 16” – 24” per typical project requirements, therefore creating a higher R-value per section as compared to competing materials which often use large on-center spacing conditions that aren’t practical and eliminate fasteners and through metals to achieve their desired test results. In addition, this innovative GreenGirt CMH products offers the thinnest insulative cross-section available, resulting in the highest strength per U-value/R-value ratio possible.

Due to its innate ability to maintain the insulation material with compression and thermoset splines, SMARTci systems with GreenGirt CMH sub-framing do not require insulation pins and fasteners. This eliminates not only through-insulation metal but also blind and through-wall fasteners. The flexible platform also allows for Z-profiles, clips, and adjustable brackets, making it easy to customize the system or CMH products to your specific needs.

Furthermore, GreenGirt CMH boasts a higher U-value and R-value than other metal, pad, and washer thermal break or FRP products, resulting in the highest real-life and true thermal efficiency application possible with realistic and real-life on-center spacing between components.

GreenGirt Composite Metal Hybrid (CMH) has been thoroughly proven and tested for thermal efficiency and performance. Both modeling and traditional formula-based studies have compared the thermal performance of GreenGirt CMH with other materials, such as steel and aluminum, thermal break pads/washers, and fiber-reinforced polymer (FRP) products. The results consistently show that GreenGirt CMH outperforms these materials in terms of strength, thermal conductivity, and efficiency.

Differential Scanning Calorimetry (DSC) Testing

Differential Scanning Calorimetry (DSC) is an analytical technique used to measure the heat capacity of materials by measuring the heat that is released or absorbed during a temperature–controlled transition. These transitions include thermal events such as crystallization, melting, phase changes, and reactions. DSC is able to distinguish between endothermic and exothermic reactions, providing insight into the thermal behavior of samples.

Hygrothermal Modeling

Hygrothermal modeling with WUFI is used to predict the mechanisms of heat and moisture transfer across various building components. It is used to analyze building materials, including their ability to resist or absorb moisture, or the effect of climate and other environmental factors on the building‘s energy performance. It can also assess the risk of condensation and the development of mold and mildew in building components.

No Through-Metal or Through Fasteners

No–through metal or through-fasteners is a vital component of continuous insulation systems as it is used to eliminate thermal bridging. Thermal bridging occurs when a conductive material is placed in contact with an insulation material, allowing heat to transfer through it. This can lead to increased energy costs. No–through metal or through-fasteners eliminates this issue as it is designed to not allow any energy transfer and acts as a thermal barrier.

Eliminates Thermal Bypasses

Eliminating thermal bypasses is vital for ensuring the highest efficiency of building enclosure systems. It directly enhances the building’s ability to retain heat during colder months and stay cool in warmer months, leading to substantial energy savings. Furthermore, addressing these bypasses improves occupant comfort and contributes to a structure’s overall sustainability by minimizing its environmental impact through reduced energy consumption.
