AAMA Window Testing: An Overview

7 minutes read

What is AAMA Window Testing?

When it comes to ensuring the quality and performance of windows, the American Architectural Manufacturers Association (AAMA) plays a crucial role. AAMA window testing is a comprehensive process that evaluates the performance of fenestration products, including windows, doors, and skylights. By undergoing AAMA testing, manufacturers can demonstrate that their products meet industry standards and provide customers with reliable and durable solutions.

Aama window testing

The AAMA is a leading trade organization for window manufacturers and professionals, advocating for technical advancements and setting industry standards since 1936. The AAMA works closely with organizations like the International Code Council (ICC) and the National Fenestration Rating Council (NFRC) to ensure that products meet both structural and energy efficiency requirements.

NAFS standard

NAFS, or The North American Fenestration Standard (NAFS) is a vital benchmark for evaluating the performance of fenestration products like windows, doors, and skylights. It works in conjunction with the AAMA window testing to ensure that these products meet structural and energy efficiency requirements. The NAFS standard has undergone updates, with the 2022 version AAMA/WDMA/CSA 101/I.S.2/A440 for Windows, Doors, and Skylights being the most recent.

The standard provides comprehensive guidelines and harmonization for a wide range of fenestration products. It also includes three additional operator types: folding door systems, parallel opening windows, and top turn reversible windows. The goal is to offer a unified performance specification across borders and facilitate seamless trade between the U.S. and Canada. Copies of the standard can be purchased online from the American Architectural Manufacturers Association, Canadian Standards Association, or Window & Door Manufacturers Association.

What is the difference between AAMA 502 and 503?

AAMA 502 and 503 are two specific testing protocols within the AAMA window testing framework. The AAMA 502 is the Voluntary Specification for Field Testing of Newly Installed Fenestration Products. This guide provides detailed test procedures to minimize air and moisture penetration in new window installations. It also includes verbiage that can be directly inserted into project specifications, saving time and effort. However, it is important for contractors to establish specific testing parameters such as areas, quantity, and testing pressures.

On the other hand, the AAMA 503 is the Voluntary Specification for Field Testing of Windows and Sliding Glass Doors. This specification focuses on the testing of windows and sliding glass doors that are already installed in buildings. It covers procedures for air infiltration, water penetration, structural performance, and forced entry resistance. The AAMA 503 ensures that existing windows continue to meet the necessary performance standards. It’s important to note that lab testing may also be required for certain applications. 

The American Architectural Manufacturers Association (AAMA) accredits independent testing agencies, ensuring compliance with guidelines and specifications for field testing of fenestration products. When seeking AAMA 502 and 503 lab testing services, it is important to select an agency that holds current AAMA test lab accreditation certificates. Clients can request a copy of the accreditation certificate from the testing agency to verify compliance.

How are windows tested?

Windows undergo rigorous testing procedures to ensure their performance and durability. The AAMA testing protocols include air leakage testing, water penetration testing, structural performance testing, and forced entry resistance testing. These tests are conducted in specialized test chambers and follow specific guidelines established by the AAMA.

During air leakage testing, a predetermined amount of air leakage is allowed, and any escaping air is measured. Water penetration testing involves spraying the window from outside to observe if any water penetrates indoors. Structural performance testing measures the amount of wind pressure the window can resist before breaking. Finally, forced entry resistance testing evaluates the window’s ability to withstand forced entry attempts.

The number of tests conducted depends on the size and budget of the project. The project architect, manager, or owner specifies the amount and locations of the windows to be tested. Testing is typically done at different intervals, such as 5%, 50%, and 90% completion for large projects. Early testing can help identify design flaws and prevent expensive repairs later on. Of course, this kind of field testing is not a necessary test if a company buys already tested products. 

As an example, you can see the types of testing procedures that Vistaza products have been objected to in order to ensure optimum structural performance:

Implications of AAMA certification for developers

AAMA certification for windows has significant implications for developers. Certifications such as the AAMA Gold Label indicate that the manufacturer has undergone independent and unbiased testing to meet stringent standards. Gold Label windows, for example, must meet specific criteria for air leakage, water penetration resistance, and structural strength.

By choosing AAMA-certified windows, developers can ensure that their buildings meet industry standards for air and water tightness, as well as structural integrity. This can contribute to energy efficiency, occupant comfort, and long-term durability. AAMA certifications provide peace of mind to developers, knowing that the windows installed in their projects have been thoroughly tested and proven to meet the highest quality standards and their ideal performance classes for their projects.

Furthermore, AAMA certifications can enhance the market value of a building. Buyers and tenants often prioritize energy efficiency, durability, and overall performance when choosing a property. AAMA-certified windows can serve as a selling point. Whether it’s the AAMA 502 water test, AAMA 1503 testing, or AAMA 910 life cycle testing, they attract potential buyers or tenants who value these qualities.
