Discussing the value of investing in triple pane, or triple glazed, windows elicits contrary opinions from homeowners, contractors, and manufacturers alike. Triple pane windows offer an additional glazing layer with a low-emissivity (low-e) coating. Low-e is a clear window coating technology that traps heat and allows light to pass through the window. Triple pane windows have two low-e coats as opposed to one coat in double pane windows. Triple pane windows have two low-e coatings and an insulating gas that fills the space between each pane, making them highly insulated and significantly decreasing energy and heat loss, especially in wintry climates.
A window’s U-factor measures thermal conductivity and determines how much heat is allowed through. The lower the U-factor, the better insulated the window. The International Association of Certified Home Inspectors recommends that in Northern climates, a window’s U-factor should be less than or equal to 0.30. Top performance, double pane windows can have a U-factor of 0.30 or lower. Triple pane windows can have a U-factor as low as 0.15.
Beyond just being energy-efficient, triple pane windows can also help reduce condensation. It is important to understand that condensation on windows is natural and not completely preventable. However, the low U-factor, triple pane windows resist condensation better than others. Also keep in mind that if you can see moisture trapped between the panes of your current windows, it is time for replacements. Fortunately, you can have your windows replaced any time of the year. Even in the cold, winter months.
