Selecting the right continuous insulation system shouldn’t feel overwhelming. With codes tightening on thermal efficiency standards, performance expectations rising, and multiple products to evaluate, it’s easy to get lost in the details. That is why Advanced Architectural Products created a set of interactive online tools. These tools allow you to compare options side by side, see how each system performs, and quickly identify the best Z-girt solution for your project’s specific requirements. In just a few clicks, you move from confusion to clarity and gain confidence that your continuous insulation selection balances efficiency, compliance, and performance.
A2P’s Five Interactive Continuous Insulation Selection Tools
Z-Girt Classification Chart

A2P’s Z-girt classification chart classifies Z-girt products into four categories based on specific performance requirements expected of continuous insulation systems:
- Class I – Composite metal hybrid systems
- Class II – Perforated thermal metal Z-girt systems
- Class III – Fiber-reinforced polymer (FRP) Z-girt systems
- Steel Z-girts/legacy systems
This chart provides a visual aid to demonstrate the most to least effective continuous insulation system depending on which performance requirements are the most important to the project.
You can view the Z-girt classification chart on A2P’s website or download the chart today.
Z-Girt Product Selector

The Z-girt product selector tool is an interactive page that allows you to select a continuous insulation system based on your project’s performance requirements.
You can discover the best solution for you based on the system’s lifespan, structural strength, thermal static performance, how effective the system is on eliminating thermal bypass, if the system complies with NFPA 285, if the system provides an air/weather barrier, the type of installation framing involved, and how much the system retains the insulation’s nominal R-value per inch.
The tool’s results reveal and describe the best continuous insulation system for your next project, making the selection process even easier.

Systems Comparisons Chart

The systems comparisons chart is a page on A2P’s website that compares different continuous insulation systems based on a selection of desired performance requirements.
Specifically, this chart compares the following systems:
- The SMARTci® building enclosure system
- The GreenGirt CMH™ continuous insulation system
- 16-gauge steel Z-girts
- Perforated metal Z-girts
- FRP Z-girts
This chart is a clear demonstration of the different performance requirements each system meets. The results allow you to understand which systems deliver high-quality performance, and which ones would fall short on performance after installation.

Thermal Calculator

A2P’s thermal calculator is an active tool that allows you to input your energy savings goals and discover how much money you can save on utility bills by installing GreenGirt CMH and SMARTci systems.
You can calculate energy savings based on your project’s building square footage, location, and which base system is being utilized.
Results show the annual costs saved in energy operations and the half lifespan cost savings, demonstrating short-term and long-term results of installing GreenGirt CMH and SMARTci systems.

Technical Library

The technical library on A2P’s website is an expansive hub of data and technical reports on GreenGirt CMH, SMARTci, and GreenGirt Steel™ systems, helping you to make an informed decision on which system is right for your next project.
Resources in the technical library include: data sheets, installation support guides, technical studies, specification documents, and product brochures.
Filters on the page allow you to focus your search to discover exactly what you need to know about these systems and how they can leverage your next project.

Frequently Asked Questions
What are A2P’s interactive tools for comparing continuous insulation systems?
We have five interactive tools on our website to help you compare continuous insulation options side-by-side: our Z-Girt Classification Chart, Z-Girt Product Selector, Systems Comparisons Chart, Thermal Calculator, and our Technical Library.
What criteria does the Z-girt product selector use to recommend a continuous insulation system?
The Z-girt product selector lets you choose performance priorities and then recommends a system based on factors including lifespan, structural strength, thermal static performance, ability to eliminate thermal bypass, NFPA 285 compliance, whether it provides an air/weather barrier, the installation framing type, and how well it retains nominal R-value per inch.
Which continuous insulation systems are compared in A2P’s systems comparisons chart?
The systems comparisons chart compares SMARTci, GreenGirt CMH, 16-gauge steel Z-girts, perforated metal Z-girts, and FRP Z-girts against different continuous insulation performance requirements.
