Standard Practices for Air Leakage Site Detection in Building Envelopes and Air Barrier Systems

ASTM E1186 - Test Method for Determining Air Leakage Site Detection in Building Envelopes and Air
Barrier Systems.

1. A pressure differential of a minimum of 10Pa and up to a maximum of 50Pa is to be applied to
the building envelope.

2. Pressurization or depressurization test shall be conducted for a period of at least 10 min.

Importance of Smoke Testing for Air Leakages


Energy Efficiency

Air leaks can result in substantial energy loss, leading to increased utility bills and decreased operational efficiency. Smoke testing helps locate these leaks accurately, allowing organizations to address them promptly and optimize energy usage.


Indoor Air Quality

Air leaks can introduce pollutants, allergens, and contaminants into indoor environments, compromising the health and comfort of occupants. By detecting and resolving air leakages through smoke testing, the quality of indoor air can be significantly improved, ensuring a safe and healthy environment.

Equipment Performance

In industrial settings, air leakages can negatively impact the performance and reliability of equipment, leading to production delays, increased maintenance costs, and potential equipment failure. Smoke testing aids in identifying and rectifying leaks promptly, optimizing equipment performance, and minimizing downtime.

Smoke testing by Buildingdoctor employs the use of non-toxic, artificially generated smoke, which enables us to trace air leakages accurately. The smoke can easily penetrate and reveal leaks in ductwork, pipes, vents, or building envelopes, providing visual confirmation of the leak's location.
