Air Leakage Explained By New Edge Window Replacement Chicago, IL

Measuring Air Leakage in Windows

When window companies Chicago are calculating the air leakage of a window, it can be a bit complex. They would have to take into account both square and cubic measurements as well as wind speed. The unit of measure used to calculate air infiltration is ‘cubic feet per minute per square foot. Here the air leakage rating tells us how many cubic feet of air is able to pass through a window in one minute with the wind blowing at a constant speed of 25 mph divided by the total area of the window. Pretty simple, right?

You may think that calculating air leakage is complicated and overwhelming, don’t worry because our window company Chicago is here to set the record straight.

It will make it easy to compare the air leakage ratings to different window lines and options, so you know what you’re getting. The only thing that you need to know is the lower the air leakage rating, and the less air will be able to pass through the window. In order for a window to receive an ENERGY STAR®️ rating, it must have an air leakage rating of 0.30 or lower.
