Understanding NFRC Labels

When choosing components for your home, you want the best quality you can afford. However, as Renewal by Andersen® of Milwaukee points out, there are more factors to consider rather than how your windows are made and how long they may last.

Its energy efficiency can also play a factor. When choosing replacement windows, here are the labels to watch out for so you can gauge their energy performance.

Solar Heat Gain Coefficient

This can come in handy when you would like to cool down during the summer season. This is because it will hint how a product can resist unwanted heat gain. To measure this, look for low numbers ranging from 0 to 1  on the label. This usually means that you’ll be spending less on cooling.

U-Factor

While the first focuses on keeping the heat out, this one is the opposite. A double-hung window with a low number means it can prevent heat from escaping from the room. Look for one that ranges from 0.20 to 1.20.

Visible Transmittance

Temperature is not the only factor to consider when shopping for a window. If a label has a high number ranging from 0 to 1 in its visible transmittance, it shows how well the product can effectively light your interior with daylight. This way, you won’t have to rely solely on artificial lighting.

Air Leakage

As already stated in its name, the air leakage number will help you measure how much air those picture windows you just bought will be allowed into your room. Keep an eye out on low numbers ranging from 0.1 to 0.3.

Condensation Resistance

While optional in an NFRC label, the CR label gives you an overview on how well the product’s inside surface will be able to formation of condensation. The higher the number, the better they will be at resisting condensation.
