What is a 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 verification of the airtightness of a building. In other words, it 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.
One of the objectives of the test is to detect air leaks. The goal being to reduce energy consumption and increase home comfort caused by excess air leakage.
How the test works
A fan is installed
Our consultants temporarily install a specialized fan in the main door of the house.
The building is depressurized
This equipment is specially designed to efficiently evaluate air loss. The test is not dangerous for the integrity of the building or for the health of the occupants.
You get your results
In relation to the volume of the building, the test gives the number of air changes per hour (ACH) and the equivalent leakage surface (ELS) of the residence.
What the results tell you
The results make it possible to compare the airtightness level of the building to other homes that were built in the same era.
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.
Blower door tests for large buildings
Blower door testing for large buildings in Canada involves depressurizing or pressurizing the structure using multiple powerful fans to measure air leakage rates and identify air leaks. The National Building Code of Canada (NBC) and provincial codes set airtightness standards for new buildings to ensure energy performance.
