What is a Window Energy Efficiency Label?

We’re here to explain what a window energy efficiency label is, and help you decipher what window energy performance ratings mean.

A window energy efficiency label helps contractors and homeowners in their search for the perfect window. Make sure to check the label before ordering your new window. This will ensure that the window you are buying will help reduce energy costs.

What are Energy Performance Ratings?

The window energy efficiency labels include energy performance ratings, which help to determine the efficiency of a variety of windows. The performance ratings include:

U-Factor

The U-factor measures the rate of heat transfer and shows you exactly you how much heat is gained or lost through your window. The lower the U-factor rating, the better it is at preventing heat from escaping.

Solar Heat Gain Coefficient

The solar heat gain coefficient (SHGC) indicates how well your window can block heat from the sun. Like the U-factor, the smaller the number, the better the window can keep heat out.

Visible Transmittance

Visible transmittance reveals the amount of visible light transmitted. The bigger or higher the visible transmittance rating of a product, the more light it allows to pass through. If you’d like to have more sunlight in your home, look for a window that has a higher visible transmittance.

Air Leakage

The air leakage rating measures the amount of outside air that is able to get inside through the window. Air leakage ratings usually range from 0.1 to 0.3. The lower the air leakage, the less air will pass through air cracks in the window.

Condensation Resistance

The condensation resistance rating measures how much condensation is able to build up on your window surface. The higher the condensation resistance rating, the better that product is at resisting condensation formation. Therefore, in a rainy climate, you may want to look into buying a window with a higher condensation resistance rating.

What are the Benefits of Having Energy Efficient Windows?

Some of the benefits of having energy efficient windows are that they provide great insulation and better noise cancellation. They can also reduce condensation and help lower the monthly heating and cooling costs.
