In South Florida, energy efficient windows have one main job: keeping the sun's heat outside. Here, most of the heat a window lets in arrives as direct sunlight, so the glass you choose matters more than anything else.
Every window we install is an ES Windows impact window with laminated glass, which already blocks most UV and dampens street noise. Add Low-E glass and a microscopically thin coating reflects much of the sun's infrared heat while still letting daylight in.

Our visualizer swaps old shuttered windows for ES impact windows on a South Florida house. Try single hung, horizontal roller, casement and picture windows in all five frame colors, then bring your favorites to your free estimate. We bring real frame and glass samples.
Every ES impact window starts with laminated glass. From there, the glass package decides how much of the sun's heat stays outside. We help you match it to how much sun each side of your house gets.

South Florida homes deal with heat, humidity and hurricane season all at once. Energy efficient windows from Guardian Impact Windows and Roofing handle all three: ES Windows impact frames, laminated glass that protects the opening in a storm, and Low-E glass options that keep the sun's heat outside. We measure, permit and install them across Miami-Dade, Broward and Palm Beach counties.
The payoff shows up every day, not just in hurricane season: cooler rooms near the windows, an air conditioner that cycles less, floors and furniture that fade more slowly, and a quieter house. Using less electricity for cooling also shrinks your home's carbon footprint.
Low-E stands for low emissivity. A Low-E coating is a microscopically thin, clear metallic layer on the glass that reflects much of the sun's infrared heat back outside while letting visible daylight through. Paired with laminated impact glass, Low-E glass gives you storm protection and heat control in the same window, with no shutters to put up.
Window energy ratings are certified through the NFRC (National Fenestration Rating Council) and change with each window style, size and glass package. As one example from ES's published specs, the ES-EL100 single hung is listed at a U-value of 0.96 with clear laminated glass and 0.64 with insulating laminated glass that has a Low-E coating, with an SHGC of 0.23 for that Low-E unit.
Many homeowners start by searching for ENERGY STAR windows. ENERGY STAR sets its window criteria by climate zone, and in Florida the focus is on blocking solar heat. Not every impact window carries the label, so compare the NFRC ratings of the windows you are pricing with the criteria for the Southern zone. For a South Florida home, a low SHGC and impact protection in the same window is what counts.
Energy efficient window replacement makes the biggest difference where old single-pane windows face the sun. At your free in-home estimate we measure every opening and show you styles, frame colors and glass. We pull the permit, our crew removes the old windows and installs your new ES impact windows, and we schedule the city inspection to close it out. Pair your windows with impact doors and a new roof to protect the whole house.
Mostly the glass. Here the job is keeping the sun's heat out, so look at the Solar Heat Gain Coefficient (SHGC), where lower means less solar heat gets through, and the U-factor, where lower means better insulation. Low-E coatings and insulating laminated glass improve both. A careful, well-sealed installation matters too.
For most South Florida homes, yes, especially in rooms that get direct sun. A Low-E coating reflects much of the sun's infrared heat while letting daylight through, so rooms stay cooler and the AC works less. It also cuts the UV that fades floors and furniture.
It depends on the number and size of your openings, the window styles and the glass package. Low-E and insulating laminated glass cost more than standard laminated glass. We measure every opening and price your exact project at a free in-home estimate. Ask about 2.9% APR or 60 months no interest while the sale lasts.
Some are and many are not, so check the exact product and glass package. ENERGY STAR sets window criteria by climate zone, and in Florida's zone the focus is on blocking solar heat. Ask for the NFRC-rated U-factor and SHGC of the windows you are pricing and compare them with ENERGY STAR's criteria for the Southern zone.
They can help. Less solar heat through the glass means the AC runs less to hold the same temperature. How much you save depends on your home: how many windows face the sun, what you are replacing, your insulation and your AC. We won't promise a percentage, but the biggest gains come from replacing old clear single-pane glass in rooms that get direct sun.
Yes. Replacing windows in South Florida needs a building permit and inspections, whatever glass you choose. We pull the permit, schedule the inspections and close it out for you.
