Less Condensation High performance windows with new glazing technologies not only reduce energy costs but make homes more comfortable as well. High-performance windows create warmer interior glass surfaces, reducing frost and condensation. High-performance windows with warm edge technology and insulating frames have such a warm interior surface that condensation on any interior surfaces is significantly reduced under all conditions. Lawrence Berkeley National Laboratory. With clear double glazing, there is condensation over the entire unit.
Condensation can occur at any points that fall on or above the curves.
As the U-factor of windows improve, there is a much smaller range of conditions where condensation will occur. Lawrence Berkeley National Laboratory. Condensation may occur at lower humidity levels on the glass edge. All rights reserved.
