Infiltrometry test

Evaluating the watertightness of your home pays off!

The infiltrometry consists of a performance test carried out with a device that allows to verify the airtightness of a building, that is to say to measure the air permeability of the envelope. In other words, the blower door test allows you to quantify and locate the outside air entering your home. Infiltrometry is an effective tool used in several energy efficiency programs, such as Rénoclimat, Novoclimat, and Energuide.

To proceed with the blower door test, our consultants create a depressurization inside the building under study using a fan installed in the main entrance door. This test is not dangerous for the integrity of the building or for the health of the occupants.

Thus, one of the objectives of the test is to detect air leaks in order to remedy them. This, in order to limit the energy losses having an impact on the comfort and on the energy consumption in heating.

Also, the blower door test, in relation to the volume of the building, makes it possible to determine the number of air changes per hour (CAH) as well as the equivalent leakage surface (ELS) of the residence. The results then allow comparison of the tightness to standards, or to averages of buildings of similar age.

Infiltrometry for contractors

Infiltrometry is also used to evaluate the airtightness of new buildings under construction. In fact, before installing gypsum, many contractors call on our services to verify the performance of their air sealing system. This allows them to detect leaks and seal them before the gypsum is installed.
