FT - What is Facade Testing?

Façade Testing

The façade of a building is an essential component that provides structural support, insulation, and aesthetic appeal. It is important to ensure that the façade is designed and installed to meet the highest standards of performance and safety. Australia has a relatively thorough set of standards that cover all elements of façade performance including testing of prototypes. One area where Australia falls short is on-site verification of building facades. This is where AAMA 501.2 comes in.


The AAMA 501.2 test evaluates the quality of the installation of exterior wall systems, for their resistance to water penetration. The test involves subjecting the façade to a controlled amount water using specialized and calibrated test equipment. Using such a method helps to identify defects that may be present in the façade. These defects might include workmanship errors, installation errors due to façade complexity, and design shortcomings. Catching these defects early, before construction is complete, means that they can be rectified before damage is caused to the building internals. The earlier these defects are caught, the easier – and cheaper – it is to fix them.

One of the primary reasons why it is important to have a façade tested to AAMA 501.2 is to provide confidence that the building is safe and secure. A faulty façade can compromise the structural integrity of the building, leading to potential safety hazards for occupants and passers-by. Additionally, uncontrolled water in a façade can lead to mold and mildew which in-turn can have significant health impacts on the occupants of the building.


A façade that has been tested to AAMA 501.2 will have undergone a thorough evaluation of its integrity and its installation quality. This testing provides confidence that the façade is installed properly and minimizes the risk of warranty claims. By testing the façade, any weak points or potential failures can be identified and addressed before they become major issues.


In conclusion, ensuring the performance and safety of your building façade is a crucial step in the success of your building. By having your façade tested to the AAMA 501.2 standard, you can demonstrate your commitment to quality, safety, and sustainability, while also providing a safer and healthier building. Don't hesitate to invest in façade testing, as it can ultimately save you money and improve the value of your property.
