Additional Notes
| Note 1: Structural Performance | The structural performance of FRP has not been conclusively determined through standardized engineering calculations, FEA, or real-world application studies, and its lifespan across different products remains uncertain. Additionally, FRP Z-girts are primarily attached using fasteners rather than bolted connections, which may affect structural integrity per the ASCE Design Guide for FRP Composite Connections, and users should consult a licensed structural engineer before application. |
| Note 2: Composite Connections | FRP composite connections are subject to unavoidable failure, resulting in a lower lifespan compared to other materials. While FRP products generally exhibit high thermal performance relative to industry standards, this is dependent on factors such as web section thickness and may vary accordingly. |
| Note 3: Thermal Bypass | FRP products may experience thermal bypass, which can reduce thermal performance by 25–50% of the R-value due to gaps, cracks, and air circulation around installation panels caused by manufacturing tolerances or installation errors. Unless insulation is properly profiled— which is not indicated for these products—thermal efficiency may be significantly compromised. |
| Note 4: Fire | FRP products, when not steel reinforced, may pose a liability under fire conditions due to their inherent material properties. Additionally, there is no uniform NFPA 285 standard applicable to all FRP product configurations, as fire performance varies based on specific applications and the presence of mineral or cement panel reinforcements. |
| Note 5: GreenGirt Steel Thermal Performance | When using rigid insulation with GreenGirt Steel, thermal performance can be improved by eliminating air movement behind and between insulation panels. Insulation effectiveness may vary based on installation quality and the ability to properly fill voids, and results are not guaranteed across all applications. Consult A2P engineering for further information. |
The information presented here is based on current product and market data available at the time of programming. A2P provides this selector as a service and makes no claims regarding specific products, their performance, or suitability for any particular application; users should conduct independent verification before making decisions.

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.
