Energy Efficiency
Impact Windows That Pay You Back Every Month
Florida homeowners run their AC harder than almost anyone in the country. The right impact windows don't just protect your home — they dramatically reduce the heat coming in, cut your cooling load, and lower your electric bill year-round.

Your Windows Are Your Home's Biggest Energy Leak
Standard single-pane or older double-pane windows let solar heat pour into your home all day. Your AC runs longer, works harder, and costs more — every single month. Modern impact-rated insulating glass with Low-E coatings blocks the heat before it enters, keeping your home cooler without making your HVAC system fight for it.
ENERGY STAR Certified
What ENERGY STAR Certification Actually Means
ENERGY STAR is a U.S. Environmental Protection Agency program that certifies products meeting strict energy performance standards. For windows and doors, ENERGY STAR certification means the product has been independently tested and verified to reduce energy use compared to standard products — not just claimed by the manufacturer.
Independent verification
ENERGY STAR products are tested by accredited laboratories and certified by the National Fenestration Rating Council (NFRC). The ratings on every certified window — U-Factor, Solar Heat Gain Coefficient, and Visible Transmittance — are independently verified, not self-reported.
Climate-zone specific
ENERGY STAR sets different performance thresholds for different climate zones. Florida falls in the Southern climate zone, which prioritizes low Solar Heat Gain Coefficient (SHGC) ratings — meaning the glass is optimized to block solar heat, which is exactly what South Florida homes need most.
Insurance and utility incentives
Many Florida utility companies offer rebates for ENERGY STAR certified window replacements. Combined with the hurricane protection insurance discount, ENERGY STAR windows can deliver savings on both your electric bill and your homeowner's insurance premium.
The Science Behind the Savings
How Impact Glass Keeps Your Home Cooler
Not all impact glass is the same. The energy performance of your windows depends on the glass package — the combination of coatings, layers, and gas fills that determine how much heat and UV radiation passes through.
Low-emissivity (Low-E) coatings are microscopically thin metallic layers applied to the glass surface. They reflect infrared heat back outside while still allowing visible light through — so your home stays bright without becoming a greenhouse. Low-E laminated glass is the standard in quality impact windows today.
Solar Heat Gain Coefficient (SHGC)
0.22–0.27 typical
U-Factor
0.28–0.35 typical
UV Blocking
Up to 99%
UV Protection
Protect Your Furniture, Floors, and Family
Ultraviolet radiation is responsible for fading hardwood floors, bleaching furniture fabrics, and degrading artwork over time. Standard glass blocks very little UV. Low-E laminated impact glass blocks up to 99% of UV rays — protecting your interior investment without darkening your home.
Furniture & Upholstery
UV rays fade fabric colors and degrade foam and leather over time. Low-E glass dramatically extends the life of your furniture.
Hardwood & Tile Floors
Direct UV exposure causes hardwood to gray and tile grout to discolor. Impact glass with Low-E coating protects your flooring investment.
Artwork & Valuables
Paintings, photographs, and collectibles are highly sensitive to UV degradation. Low-E glass provides museum-quality UV protection.
Skin Protection Indoors
UV rays penetrate standard glass and contribute to skin damage even indoors. Low-E laminated glass blocks the UV spectrum that causes the most harm.
