FAQs
Before starting any renovation project, it’s a good idea to determine your goals in terms of comfort, health and cost effectiveness.
We all know the telltale signs of insulation deficiencies:
According to the SCHL, air leaks are most often located near the ceiling and end joists.
All together, the air leaks in a house can amount to having a 10″ x 10″ hole in an outdoor wall!
Of course, the result is an uncomfortable environment which, in the long-term, may lead to more serious problems. This is particularly due to humidity, which has a tendency to build up inside the walls and cause mould.
There are tests to measure the level of mould, air infiltration and humidity.
Infiltrometry tests are part and parcel of a professional energy efficiency evaluation. Conducted with specialized equipment, it measures the air leakage of your house. Even if this test is not required under the new RBQ standards, it is highly recommended.
As a rule of thumb, air leakage should not exceed 2.5 air changes per hour.
Take note that there are subsidies for renovations in Québec.
