Air Infiltration

To some extent, every home, regardless of age or location, needs to “breathe.” You may feel some air coming into your home around windows. This is air infiltration, and it is the result of air pressure differences between the inside and outside of the home.

AAMA (American Architectural Manufacturer’s Association) has set the industry standards for maximum allowable air infiltration at .30 CFM (Cubic feet per minute) during a 25 MPH wind. This is equal to 2.25 Gallons of air leaking through the window every minute.


Why Do Some Windows Leak Air More Than Others?

All windows, no matter what material used, have some level of air infiltration. However, certain windows prevent air infiltration better than others. Ideal’s vinyl window design and construction prevents air leakage, keeping your home comfortable and draft-free. Poorly designed windows lack the built-in air locks, weather stripping, and barriers necessary to prevent air infiltration. Without these window features, air pushes between the sash and other areas of the window.

Here at Ideal, we know how uncomfortable a home with drafty windows is. So we manufacture our vinyl windows with weather barriers that go far beyond the industry standards for minimizing air infiltration.

What's in the Label?

The NFRC's Energy Performance Rating Label have been designed by the NFRC to provide consumers with accurate energy performance ratings for all window and door products. The testing requirements are all determined by the NFRC. Testing must be performed by certified labs and the results are validated by independent agencies.
