How to Determine a Window’s Overall PerformanceJun 13, 2019
It definitely pays to invest in energy-efficient and durable windows because they can help you get significant savings on your heating and cooling costs. Quality windows can improve your indoor comfort and give you a more peaceful environment by blocking unwanted outdoor noise.
But you need to adequately assess a window’s performance before purchasing it. Here’s how.
Solar Heat Gain Coefficient (SHGC) – It measures how much solar radiation is transmitted through a window. A lower SHGC means less solar heat enters your home.
U-Factor – Windows with low U-factors are beneficial in both cold and warm climates. It’s the amount of heat lost or gained through a glass. The lower the U-factor, the more a window resists heat flow and the better its insulating capabilities.
Air Leakage (AL) – Cracks in the windows cause warm or hot air to enter or escape your home. The lower the AL, the less air escapes through the cracks in the window. At Rogers Roofing, our tightly sealed casement windows resist air and moisture.
Visible Light Transmittance (VT) – It indicates how much visible light passes through a window. Modern windows have special coatings that blocks different kinds of visible, infrared and ultraviolet (UV) light. More light is transmitted in windows with higher VT.
Condensation Resistance (CR) – CR is how well a window resists condensation formation on its inner surface. It’s rated between 1 and 100. The higher the CR, the better a window resists condensation.
Sound – Tightly sealed and well-insulated windows are significantly quieter than old, leaky ones. Sound resistance is linked to the mechanisms used to control heat loss. This means you can reduce sound transmission by reducing air infiltration.
