Not all energy-efficient Davis CA specialty windows are the same. Numerous windows are specifically designed for different climates. If you live in the Midwest where it is usually hot and dry, for instance, your window must be able to block outdoor heat to sustain a comfortable temperature inside your home.

That’s why a window with a U-factor and SHGC of 0.3 or lower is beneficial for your home, especially if you live in the northeast region, where it’s typically cold. This can keep the warm air inside your home and the cold air out. (I would relocate these red articles under the specific labels. This content doesn’t really introduce the article clearly)

More people are now replacing their windows with energy-efficient ones because of their many benefits. However, many are still confused about which window to choose.

The National Fenestration Rating Council (NFRC), an industry-recognized nonprofit certifying body for windows (and doors), and the U.S. Department of Energy label every product they’ve evaluated with their rating of the product’s performance.

A product with the ENERGY STAR label of the Department of Energy means that the product complies with the strict standards of the government on energy efficiency. NFRC’s label, on the other hand, provides the raw numbers of the window’s performance.

When you go shopping for windows or other products, look for these labels:

The National Fenestration Rating Council (NFRC) Label

U-Factor. This measures the performance of the window’s capacity to prevent heat from escaping. The lower the U-factor, the better a product keeps in the heat.
Solar Heat Gain Coefficient. This measures how much heat from the sun is blocked. The lower the number, the better.
Visible Transmittance. This is the amount of visible light that passes through the glass. The higher the percentage, the more visible light is allowed to pass.
Air Leakage. This indicates how much air from outside comes in. The lower the rating, the less air passes through.
Condensation Resistance. This is the ability of a window to stop the formation of condensation. The higher the rating, the better the window is at resisting condensation.

The ENERGY STAR Label

The ENERGY STAR label means that the product

was tested and verified by the U.S. Department of Energy,
contributes to significant energy savings, and
delivers features and performance demanded by consumers.
