Customer Reviews

Energy Star

One of the most common home improvement projects is having energy efficient windows installed in your home or office.
In Florida, energy efficient windows help to keep heat energy outside your building making for a cooler environment inside.
Window replacement of any kind can be quite a project, which means it’s very important to figure out exactly what you want out of your new windows before getting started. Energy star rated windows help you go green and protect the environment by cutting back on energy usage without going over budget on your window replacement project.

Windows that are ENERGY STAR qualified in the Southern Climate Zone must have NFRC certified performance ratings of:
• U-Factor 0.65 or less
• SHGC (Solar Heat Gain) 0.40 or less
