If you’re in the market for energy-efficient windows, you need to know how to read the National Fenestration Rating Council (NFRC) label. It tells you the energy performance ratings of the product, which lets you know whether it’s perfect for your local climate or not.
To understand what it says, All States Home Improvement explains the energy ratings you can find in it:
U-Factor
The U-Factor refers to the insulating quality of windows. It measures how well the product reduces thermal transfer, preventing unwanted heat loss. Ranging from 0.20 to 1.20, a lower number means better heat retention.
Solar Heat Gain Coefficient (SHGC)
If the U-Factor talks about preventing unwanted heat loss, SHGC pertains to limited undesirable heat gain. You will want to mind this rating to reduce your cooling costs during the hottest months of the year. Ranging from 0 to 1, a lower number means the product is better at reflecting solar heat.
Visible Transmittance (VT)
VT measures how good replacement windows are at letting in daylight. Considering the practical benefits of abundant, natural illumination, this metric helps you keep your home comfortable, healthy, and energy-efficient. Ranging from 0 to 1, a higher number means it’s better at letting sunlight in.
Air Leakage
All units, especially operating ones, allow a certain amount of air infiltration, and this rating tells you how much draft you’re likely to experience. Ranging 0.1 to 0.3, a lower number means less air passes through the product.
