Puzzled by all the window options out there? What type of window should you get? What type of assembly does it have? What about glazing? Framing? Cladding?
In this video, we talk about the benefits of energy-efficient windows. Windows with 3 panes of glass are a necessity for high-performance homes and offer other benefits such as noise reduction.
Triple glazed windows utilize three layers of glass sandwiched together over two sealed air spaces. The typical insulation value for triple-glazed windows is around R-5.
Triple glazed windows have really low heat transfer rates, making your building envelope more energy efficient. To qualify for high-performance building certifications such as Passive House, triple-glazed windows might be required. They also increase the temperature of the inside surface of the window during the winter, which reduces radiant heat loss from your body and makes you much more comfortable, even in lower room temperatures.
Look for argon-filled, Low-E coated, Energy Star rated windows with insulating spacers separating the panes.
The insulating value of windows is usually rated by the whole window U-factor and the lower the value the better. A triple glazed window can have a U-factor as low as 0.14 Btu/hr-sq ft °F (required by the Passive House standard).
In Southern, hotter climates, the amount of solar radiation that enters through a window should also be minimized. This is rated by the Solar Heat Gain Coefficient (SHGC) which is a value between 0 and 1. The lower a window’s solar heat gain coefficient, the less solar heat it transmits. Energy Star-rated windows for Southern climates should be less than 0.25 SHGC.
