How does it work?
Before the installation of gypsum, the agency of energy efficiency will send to your building site a team which will carry out a test of infiltrometry. All openings will be plugged and a machine to check the change of air in the house will be activated. The more the house is waterproof, the better the result. By choosing a structure out of water, you will receive an installation guide to refer you to procedures to follow. It should be noted that all our customers have successfully passed the first test.

The smaller the result, the more your home is waterproof.
