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.
