Condensation Resistance Factor (CRF) is a measurement used to quantify a window’s ability to resist condensation from forming. Whenever condensation is present, the first thing to look for is the atmospheric conditions…or more simply put, is your home encouraging condensation. This can come from high humidity levels and/or lack of sufficient air-flow in the home…and is magnified by windows that do not provide good insulation.
The reason why insufficient windows promote condensation is that the surface of the glass gets cooler as heat escapes.
Highly insulating windows keep the temperature on the surface of the glass warmer, and thus more resistance to condensing the moisture-rich air in the atmosphere of your home.
Our triple pane windows enhance condensation resistance of normal clear glass windows up to 49%, and can even improve normal dual pane Low E windows by over 20%.
There are many reasons to promote good cond ensation resistance. Excess moisture can lead to rotted window sills, and even mold and mildew promotion.
Triple Pane windows offer the highest CRF’s available.
