Blower door test

Assessing the air tightness of your home, a process that pays off!

The blower door test consists of a performance test carried out with a device that allows to verify the airtightness of a building. In other words, the blower door test allows you to quantify and locate the outside air entering your home. The blower door test is an effective tool used in several energy efficiency programs.

To proceed with the blower door test, our consultants create a depressurization inside the building 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.

One of the objectives of the test is to detect air leaks. The goal being to reduce energy consumption and increase home confort caused by excess air leakage.

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 make it possible to compare the airghtness to similar constructions of similar age.

Blower door test for general contractors

The blower door test 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.
