Understanding NFRC Measurements for Energy Efficiency

Because of the role your windows play in your home’s beauty and comfort, replacing them is a task that requires thorough planning. After all, you don’t want to invest in a unit that you may have to replace again in a few months.

Measurements for Energy Efficiency

One way to get it right the first time is by choosing energy-efficient units. The National Fenestration Rating Council (NFRC) has three ratings to measure a window’s efficiency. Renewal by Andersen® of Kansas City, the area’s premier provider of quality residential windows, discusses more:

What Makes Windows Energy-Efficient

The U-Factor measures the window’s heat loss, with a rating that usually falls between 0.20 and 1.20. The lower its value, the better its insulation and resistance to heat flow. If you live in a colder climate, it pays to invest in a replacement window with a low U-Factor to keep your home’s interior warm.

Meanwhile, the Solar Heat Gain Coefficient (SHGC), shows how well a window can block the heat from the sun. Often a number between one and zero, we recommend investing in windows with a low SHGC, especially during summer. This is also an important rating to check for window styles with broad glass spaces, like sliding windows.

Visible Transmittance (VT) measures the amount of sunlight that passes through a window. A higher VT means clearer window panes and more lighting. This is usually expressed between zero and one.

What Makes Renewal by Andersen Windows Superior

Apart from the three ratings, a variety of other factors, like materials and installation, affect a window’s energy efficiency.
