The Consumer’s Guide to Energy-Efficient Windows

Energy Efficiency Rating A+++

Buying energy-efficient windows for the first time takes some research and consideration: There are industry-specific terms, different coating types, and multiple framing materials to become familiar with. In order to make the best choice for your home’s new windows, follow this quick consumer’s guide to energy-efficient windows :

Getting to Know the Terms

There are many terms used to describe energy-efficient windows—such as U-factor, SHGC, and VT—which are all very important to know. A window’s U-factor is the rate at which non-solar heat can pass through the window. In comparison, the SHGC, or solar heat gain coefficient, indicates how quickly solar energy can pass through the window. Lastly, the term VT, or visible transmittance, simply denotes how much light can shine through a window.

Understanding Low-E Coatings

Most energy-efficient windows are lined with a thin layer of metal, known as a Low-E coating, which reflects heat. According to Energy Star , these coatings are so effective that they can stop 70% of solar energy coming into a house, resulting in significant cost savings.

Choosing the Right Window

There are numerous types of energy-efficient windows available, including casement, fixed, and awning models. But before you purchase a set of windows based on aesthetics, you should be aware that not all windows promote the same level of energy efficiency. For instance, sliding windows are more prone to letting air escape than any other model. So if you are trying to save money on your heating and cooling bills, a sliding window might not be the best option for you. For improved energy efficiency, consider installing fixed or hopper windows, which are virtually air-tight.

These are only a few of the facts that you should know about energy-efficient windows. To learn more about the specifications and benefits of these windows, call Window World in Orlando .
