Windows serve several key functions in both residential and commercial properties. They provide light, warmth and ventilation; they contribute to the overall aesthetics of the property; and they contribute to the mental health outhouse inside.
Homeowners must also realize that windows play an important role in making their home more energy-efficient. It is guaranteed to reduce utility bills by installing more energy-efficient windows. Improvements can also be done on existing windows, an excellent choice for those who are on a tight budget.
This article provides you with valuable information about measuring window performance and picking the best windows for increasing your energy efficiency.
The National Fenestration Rating Council (NFRC) has laid out a series of tests that gauge the energy efficiency of windows. Windows with the NFRC label are required in many locations with updated energy codes. The NFRC label shows the energy ratings of windows.
Five ratings are used by the NFRC to measure the performance of windows:
U-Factor – This measures the amount of heat loss the window can prevent. The rating falls between 0.15 and 1.2. A lower value indicates that the window is better at keeping heat inside the property. This is particularly useful for homes situated in areas that experience harsh winter conditions.
Solar Heat Gain Coefficient – This measures the amount of heat the window can block. The values fall in between 0 and 1. The lower the value, the better the window is at blocking solar heat.
Visible Transmittance – This rates how much light can pass through the window. The rating comes in between 0 and 1. Choose a window with higher visible transmittance if the goal is to allow more daylight into the home.
Air Leakage – This rating measures the amount of outside air that enters the home. Air passes through gaps or holes in the window. The value comes in between 0.1 and 0.3.
Condensation Resistance – This measures how well the window resists condensation. The higher the value, the higher the condensation resistance.
The window selection process must take into account appearance, performance and cost. There are plenty of factors to consider in choosing the best windows for the home. The first step is to determine state and local energy codes, what your area requires. The energy ratings must comply with the requirements set forth in these codes, which differ from one location to another.
Next, look for the NFRC and ENERGY STAR labels. These help ensure that the windows have above-average energy performance. Performance properties indicated on the NFRC label also help determine the technologies used in the windows and how they affect energy performance.
Third; aside from ratings it is critically important to have the windows properly installed. Only professional contractors should do the installation of windows to guarantee optimum energy efficiency.
Measuring window performance can have a huge impact on the overall energy efficiency of a home or commercial property. Choosing windows equipped with the latest technologies allow home and business owners to save a significant amount of money over the long term.
Be sure to work with reputable manufacturers and professional contractors to ensure that the most energy-efficient windows are used in your property.
