Condensation Resistance in Residential Windows

Condensation in windows occurs when the surface temperature of the glass, sash, or frame of a window is lower than the dew point of the humid air in its vicinity. Condensation in windows often occurs at the corners where the glass and frame touch.

Problems with Condensation

Condensation in windows can obstruct visibility, but more importantly, can cause water damage to the window frame and surrounding area as well as nurture toxic mold growth inside your home.

How do SeriousWindows control condensation?

We have carefully engineered and designed all of our products to nearly eliminate the possibility of condensation.

Convection-controlling inert gases such as argon, krypton, or a blend of the two, fill the air space between  insulating chambers of our SeriousGlass units in every SeriousWindows. The gases control convection because they are heavier than air. The movement that often happens with air is suppressed because the gas doesn’t move as readily as air. The gases are also better insulators than air because they have a lower conductivity rate.

Low–E glass coatings help keep SeriousWindows' interior glass temperature warmer in the winter and cooler in the summer. This is important because if the temperature of the glass is kept close to the ambient temperature of a room, the risk for condensation is greatly reduced.

A window’s spacer system is the weak link in a window and if improperly designed can facilitate condensation in the corners of a window. We believe a poorly designed spacer system can reduce the performance of a window by as much as 20%. Our spacing system focuses on warm edge technology that keeps the interior glass at the perimeter of our windows at the same temperature as the rest of the window. This technology dramatically reduces the probability of condensation and stress on the window.
