Enclosure Testing

We can test your enclosure for air and water tightness and help with diagnostics.

Fenestration Testing (Water and Air Leakage)

We test all sorts of fenestration systems, including punch windows, curtain wall, window wall, and field-built storefront systems. While we are capable of performing a variety of test methods, the three most common methods are included below. The test method that makes sense for your project will depend on your project goals. If not specified, we are happy to help you determine which is right for your project.

  • ASTM E1105 – The Pressure Chamber Test is used to quantify the water leakage resistance of your fenestration system after it has been installed in the field.
  • AAMA 501.2 – The Spray Wand Test is a diagnostic method that is applied to check the continuity of seals and gaskets in an installed system. It can also be used to check the quality of seals and gaskets in locations where it is not practical to use a pressure chamber.
  • ASTM E783 – This test quantifies the air tightness of your fenestration system. We usually perform this test in conjunction with the Pressure Chamber Test. This is used to validate that the product meets the project requirement.

Whole Building Air Leakage Testing

4EA has been performing Whole Building Air Leakage Testing for over a decade. This test will demonstrate the air tightness of your building enclosure. Whole Building Air Leakage Testing is a requirement for most buildings under the jurisdiction of the U.S. Army Corps of Engineers and for most commercial and residential buildings in Washington State. In areas where the test is not mandated, it is a valuable tool to demonstrate air tightness for long-term building energy performance and to help locate air leaks which can then be addressed.

  • ASTM E779 – The Blower Door Test uses large fans to quantify the amount of uncontrolled air leakage of the finished building enclosure.
  • ASTM E1186 – This is a qualitative series of tests that we can perform in conjunction with the Blower Door Test. This method includes infrared thermography and smoke tracing.

Diagnostics

When building enclosure testing doesn’t go to plan, we work to Find a Solution. We’re problem solvers at heart and will work with your team to diagnose the root cause of a test failure, help key stakeholders understand the root cause, and provide recommendations on corrective action.

Our deep understanding of how fenestration systems and building enclosures are built and work helps us provide value to our clients.
