Composite Metal Hybrid (CMH) vs Generic Fiber Reinforced Polymer (FRP): Engineering Study
Performance of composite metal hybrid (CMH) and fiber reinforced polymer (FRP) composite substructure materials for exterior cladding attachment has greatly improved over the last several years. High performance composite metal hybrid (CMH) and, more recently, generic fiber reinforced polymer (FRP) z-girts are currently available as thermally efficient continuous insulation system components. Thermal efficiency in continuous insulation systems has never been more prevalent than it is today.
As building codes, such as ASHRAE 90.1 (American Society of Heating, Refrigerating and Air-Conditioning Engineers) along with other standards and regulations, become more focused on sustainability, commercial building practices, methods, and material must adapt. It is critical to maintain or improve the engineering, structural and durability characteristics of the the thermally efficient product. As is shown in the data contained in this paper, that is not always the case.
The purpose of this study is to review the overall performance related to best practice procedures for structural analysis. Along with standard wall loading conditions of composite substructure materials such as composite metal hybrid (CMH) and fiber reinforced polymer (FRP). Based on accurate finite element analysis (FEA) simulations, this paper explores the structural analysis and durability of both GreenGirt CMH material and generic fiber reinforced polymer (FRP) materials. As well as compare the structural integrity of z-girts of equivalent depth.
