Thermography and Air Permeability

What is Thermography?

Thermography is an advanced technique that involves capturing and analyzing surface temperature variations of different elements using an infrared thermal camera. This allows for diagnosing the condition of various building systems such as air barrier discontinuity, lack of insulation, electrical, mechanical, or thermal issues, without contact and without causing destruction. This inspection technique also helps evaluate the airtightness and detect water or moisture infiltration in the roofing system as well as in different components of a building envelope.

In this regard, it is preferable to conduct thermography in an environment with a temperature differential of 10°C or more between the inside and outside of the building. This makes it easier to obtain a clear image of temperature variations in order to detect problematic areas.

Our experts will perform a thermographic inspection of your building with photos (thermograms). We will then analyze the images and provide you with a report of the results along with recommendations and corrective measures.

What is an Air Permeability Test?

An air permeability test can be conducted to evaluate energy efficiency or to identify weak points that allow air and moisture to pass through the building. Using an infiltrometer connected to a fan, the building is subjected to negative pressure, allowing the engineer to collect data on air tightness, precisely locate sources of leaks, and assess their severity.

Uncontrolled air movements in a building create several problems, including increased heating costs. These same air leaks make homes uncomfortable, reduce their energy efficiency, and can cause premature deterioration of their components. In other words, air permeability testing is a beneficial way to ensure the airtightness of a building by sealing air leaks.
