Best PracticesA2P1050: The Effects of Sub-Framing on Structural Integrity

May 30, 2023

When selecting materials for construction projects, architects and engineers must consider the implications their choices will have on structural integrity. This decision can become overwhelming with many sub-framing materials now available in today’s market. At Advanced Architectural Products, we believe that understanding how different types of sub-framing affect the overall stability of a structure is paramount in planning large-scale buildings and other infrastructure.

In this article, we’ll explore the intricacies of sub-framing design within the building envelope – from steel and wood applications to new products developed with advanced technologies – and discuss why certain materials are better suited to particular requirements. We hope our insights into this fascinating area will help architects make informed decisions when they select building components that are integral to ensuring long-lasting structural solutions.

What is Sub-Framing, and What Are Common Sub-Framing Materials?

Sub-framing is used in construction to enhance the performance and longevity of building products within the building envelope. This process involves using a secondary framework, called the sub-framing, installed behind the primary cladding material.

Selecting suitable materials for sub-framing is critical for ensuring long-term performance and energy efficiency. Using highly durable materials that resist moisture is recommended, as they can help prevent mildew or mold growth while reducing energy consumption. In addition, using best practice materials offers higher durability and a longer lifespan than traditional materials such as steel or aluminum.

Legacy materials, such as steel or aluminum, are chosen for their durability and strength within the building envelope. However, recent advances in sub-framing components have been made possible through cutting-edge technology and composite materials. These modern sub-framing components are designed to address the downfalls of legacy materials, such as thermal performance and moisture-related issues.

One key feature that sets these modern sub-framing components apart from traditional options is their thermal conductivity. As a result, modern sub-framing components can help prevent energy transfer and reduce energy consumption by using high-performance insulating materials. Additionally, many modern sub-framing components can offer improved resistance to moisture-related issues.

Composite materials such as fiber-reinforced polymers (FRP) offer benefits, including corrosion resistance, lighter weight, and a reduction in thermal conductivity compared to metal sub-framing. However, if best practice installation methods are not utilized with FRP, sub-framing can still have similar downfalls to metal. Also, FRP does not have the same structural strength as traditional sub-framing materials such as steel or aluminum. For example, suppose through-metal and through-insulation fasteners are used with FRP sub-framing. In that case, energy can still transfer through the sub-structure and building envelope, possibly resulting in higher energy consumption, moisture-related problems, and potential structural integrity issues.

How Does Sub-Framing Affect Structural Integrity?

The structural integrity of buildings is crucial in ensuring their safety and durability. One aspect that affects a building’s structural integrity is sub-framing. Its impact on the overall strength of a building cannot be underestimated. Installing sub-framing that is not strong enough or poorly designed can render a building unstable, which can have disastrous consequences. Therefore, architects and engineers must carefully consider the sub-framing design during the building’s construction to ensure the longevity of a building. The responsibility of ensuring sub-framing is done correctly requires expertise, precision, and attention to detail.

As a best practice sub-framing manufacturing company, we understand the importance of providing strong and reliable structural support to any building project without sacrificing thermal performance or structural integrity. Advanced Architectural Products has developed a best practice sub-framing solution: GreenGirt composite metal hybrid (CMH).

GreenGirt CMH Sub-Framing

GreenGirt composite metal hybrid (CMH) sub-framing is a best practice continuous insulation solution for building envelopes. GreenGirt CMH combines the best of both metal and composites with the strength of structural steel with the thermal performance of composites. GreenGirt CMH comprises a Z-shaped composite profile with interlocking continuous steel metal plates inserted into each flange. It houses insulation material while also providing maximum cladding and substrate attachment support. By using best practice GreenGirt CMH sub-framing, we can distribute the weight of a building more evenly and eliminate thermal bridging, which reduces the stress n the primary structure and helps to improve its overall integrity.

Best practice GreenGirt CMH sub-framing can be customized in a SMARTci continuous insulation system to fit any building design, including new or retrofit projects. It can also be used to support cladding systems, allowing for a wide variety of creative and functional design options. By incorporating best practice GreenGirt CMH sub-framing into building projects, we can help ensure that structures are safe, strong, and built to last for many years.

Benefits of Using GreenGirt CMH Sub-Framing for New Construction or Retrofit Projects

There are countless variables to consider when it comes to new construction or retrofit projects. However, one crucial factor that shouldn’t be overlooked is the installation method and sub-framing material choice. At Advanced Architectural Products, we truly believe that utilizing best practice GreenGirt CMH sub-framing can provide a wide range of benefits for your building project. Frost cost savings and improved thermal performance. From increased structural integrity and enhanced durability, our expertly crafted sub-framing solutions are designed to optimize your project’s overall efficiency and quality.

Numerous industries have benefited from GreenGirt CMH sub-framing, including meeting strict energy codes and guidelines while improving overall sustainability. It has also been used in large-scale commercial building projects to provide structural support for heavy cladding materials, improving overall structural integrity.

Key Considerations When Choosing a Sub-Frame Material

As a best practice sub-framing manufacturing company, we understand the importance of choosing a suitable material for your sub-frame. The material you choose will affect your sub-frame’s stability, durability, and overall quality. When deciding, it’s essential to consider factors such as weight, strength, corrosion resistance, and material availability. Aluminum, steel, and FRP are some of the most common materials used for sub-frames, each with unique advantages and limitations.

At the end of the day, the key consideration should always be choosing the material that will best suit your project’s specific needs and requirements. With our expert knowledge and experience, we can help guide you through this decision-making process to ensure that you make the right choice for your sub-frame.
