Signs your sliding door is wasting energy.
Older sliding doors are some of the biggest energy leaks in a Florida home. Single-pane glass, aluminum frames with no thermal break, and worn weatherstripping all let heat pour into your living space. Your AC works overtime to compensate. If your door was installed before 2010, chances are it doesn't meet current ENERGY STAR standards for the Southern climate zone. Upgrading to a modern energy-efficient door can cut your cooling costs near that opening by 10% to 25%.
Hot Glass to the Touch
Touch your sliding door glass on a sunny afternoon. If it's hot, your glass isn't blocking solar heat effectively.
High Electric Bills
Florida homeowners spend $200 to $400+ per month on AC. An inefficient sliding door makes it worse.
Single-Pane Glass
If your door has single-pane glass, it has almost no insulating value. Modern doors use dual-pane with argon gas fill.
Foggy or Cloudy Glass
Condensation between the panes means the seal has failed. The insulating gas has escaped and the glass offers poor thermal performance.
What is Low-E glass and why does it matter?
Low-E stands for low emissivity. It's a microscopic metallic coating on the glass that reflects infrared heat while letting visible light pass through. In Florida, Low-E glass keeps the sun's heat outside where it belongs. You won't see the coating, but you'll feel the difference. The area near the door stays cooler, and your AC doesn't have to run as hard. Andersen, Pella, and PGT all offer Low-E glass options on their sliding doors.
Understanding U-factor and SHGC ratings.
Two numbers tell you how energy-efficient a door really is. The U-factor measures insulation performance. Lower is better. For Florida, look for a U-factor of 0.30 or less. SHGC (Solar Heat Gain Coefficient) measures how much solar heat the glass lets through. In our climate, you want a low SHGC of 0.25 or less. ENERGY STAR certified doors for the Southern zone meet both thresholds. We'll help you pick the right specs for your home and budget.
How we install your energy-efficient door.
Consultation and Sizing
We measure your opening, assess your current door, and recommend the best energy-efficient options for your budget and needs. We'll explain the U-factor and SHGC differences between brands.
Remove the Old Door
We carefully remove your existing door, clean the opening, and inspect for any frame damage that needs fixing before the new door goes in.
Install the New Door
We set, level, and secure the new door. Proper shimming and flashing ensure maximum energy performance and a watertight seal.
Seal and Test
We apply sealant, install fresh weatherstripping, and test the door for smooth operation, locking, and draft elimination.
Energy-efficient and impact-rated in one door
Need hurricane protection and energy savings? Many manufacturers offer doors that are both impact-rated and ENERGY STAR certified. PGT, Andersen, and Pella all make combination models. If you live in the Wind-Borne Debris Region (east of US 1 on the Treasure Coast), check out our hurricane impact door installations for options that check both boxes.
