Before you can make an educated decision about which replacement windows to purchase for your home, you first need to know what features make a window energy efficient. With temperatures rising and the heat of summer in Florida, having the right window is imperative. Not only can the right window affect your level of comfort in the Florida heat, but it can also have a drastic impact on your wallet by helping you save money.  

So let’s talk about the features that make a window energy efficient. Then we’ll move on to the best energy efficient window manufacturers in the window industry today.

Look for the ENERGY STAR® Information & Logo

Window Energy Star Ratings

A window manufacturer has to meet specific criteria for its climate zone to receive an ENERGY STAR® rating. Performance criteria are based on ratings by the National Fenestration Rating Council (NFRC) and vary for different climate zones. The ENERGY STAR® rating is one that indicates to a consumer that any given product has been tested and meets the energy-saving standards that qualify it to receive such a rating.

What Makes a Window Energy-Efficient?

Quality Frame Materials
To be energy efficient, the frame of the window must be made out of high-quality materials in order to prevent heat from escaping. There are a number of different types of frames, including fiberglass, vinyl, and wood. Some frames are made up of a combination of different materials while some are composite frames, meaning that the materials are blended together during the manufacturing process.

Multiple Panes
Windows with multiple glass panes are becoming more common in newer homes as improved technology allows for better heat insulation. Windows with multiple panes of glass provide greater shielding from the outside elements while keeping your home cooler than single-pane windows. The gas between the panes can retain more heat than regular air. Windows can have two, three, or more panes for greater insulation.

Low-E Glass
Low-E or low emissivity refers to an ultra-thin coating on windows that reflect infrared light to retain heat in the winter and deflect heat during the summer. This technology can significantly impact heat transfer from windows and its ability to insulate properly. Windows made with low-E glass can also deflect damaging ultraviolet rays, which can wear down the furnishings in your home.

Argon Gas Fills 
Multiple pane windows contain a space between them that is filled with gas, which retains heat better than normal air. Most window manufacturers use argon or krypton for their gas fills. These gases will not affect the air quality of your home and are odorless, colorless, and non-toxic.
