Best Window Treatments to Keep Heat Out in Florida
Florida sun is beautiful until it pours through your windows at 3 in the afternoon. Rooms heat up, the air conditioning runs nonstop and furniture starts to fade. The good news is that the right window treatments to keep heat out can make a real difference in comfort and in your cooling bill.
Sanford Verticals is a family-owned window treatment company that has served Central Florida since 1987. We help homeowners in Sanford, Lake Mary, Oviedo, Orlando and Deltona choose coverings that actually work in our climate. This guide explains what blocks heat best and why.
Why Windows Let So Much Heat In
Windows are the weakest point in most homes when it comes to heat. According to the U.S. Department of Energy, about 76 percent of the sunlight that falls on a standard double-pane window enters the home as heat. In Central Florida, where cooling season lasts most of the year, that adds up fast.
West- and south-facing windows take the hardest hit. Large sliding doors and picture windows let in even more. Choosing window treatments to keep heat out of those specific openings is often the fastest way to cool down a hot room.
Honeycomb Shades: The Energy Efficiency Leader
If blocking heat is your top priority, honeycomb shades are hard to beat. Their cell-shaped pockets trap air, which slows the transfer of heat through the window. The Department of Energy reports that cellular shades can reduce unwanted solar heat through windows by up to 60 percent when they are installed with a tight fit.
That tight fit matters. Custom measuring and professional installation reduce the gaps along the sides where heat sneaks in. Honeycomb shades also come in light-filtering and room-darkening fabrics, so you can control glare without making a room feel closed in.
Plantation Shutters: Solid Protection With Style
Shutters are another strong choice for window treatments to keep heat out. The solid panels create a barrier between the glass and the room. When the louvers are closed, very little direct sun gets through. When they are open, you can angle them to bounce light up toward the ceiling while keeping the hottest rays off your floor.
For Florida homes, material matters. Composite shutters and Eclipse vinyl shutters hold up well to heat and humidity. They resist warping and cracking in sunny rooms where real wood can struggle over time.
Roller and Solar Shades: Glare Control Without Losing the View
Many homeowners in Orlando and Lake Mary do not want to give up their view. Roller shades with a solar screen fabric solve that problem. They cut glare and reduce heat while still letting you see outside. The weave of the fabric, often called openness, controls how much light and heat pass through. A tighter weave blocks more heat. A looser weave keeps more of the view.
Roller shades also come in blackout fabrics. If you are deciding between light-blocking levels for bedrooms or media rooms, our guide to blackout vs room darkening shades breaks down the difference.
What About Blinds?
Blinds can help, but they are not the most efficient option on their own. The slats let heat pass through the gaps, and they add little insulation. They are still a practical, affordable choice for many rooms. For the hottest windows in the house, though, pairing blinds with better-insulating coverings elsewhere usually gives better results.
Make Your Window Treatments Work Harder With Motorization
Even the best shade does nothing if it stays open during the hottest part of the day. That is where motorization shines. Motorized shades can lower on a schedule before the afternoon sun hits, then rise again in the evening. You get the heat protection without having to remember to close every window.
Motorization is especially useful for tall windows and hard-to-reach openings that homeowners rarely adjust by hand.
Tips for Choosing Window Treatments to Keep Heat Out
A few simple guidelines help you get the most from your investment:
- Start with the hottest rooms and the west- and south-facing windows.
- Choose a tight, custom fit to reduce heat leaks around the edges.
- Use light-colored or reflective backings facing the glass when possible.
- Consider honeycomb shades or shutters where heat is the main problem.
- Add motorization for windows you cannot easily reach.
Sliding glass doors deserve special attention because they are often the largest heat source in a home. Our guide to the best window treatments for sliding glass doors covers the options in detail.
Room-by-Room Priorities
Not every room needs the same level of heat protection. A smart plan puts the strongest window treatments to keep heat out where the sun does the most damage.
Living rooms and family rooms with west-facing glass usually come first. These spaces take the brunt of the afternoon sun, and they are where families spend the most time. Honeycomb shades or shutters make a noticeable difference here.
Bedrooms come next, especially in two-story homes where upstairs rooms trap heat. Room-darkening honeycomb or roller shades help rooms stay cooler and make sleep easier on bright mornings.
Home offices need glare control as much as heat control. Solar roller shades keep screens readable without turning the room into a cave.
Kitchens and bathrooms face humidity along with heat. Moisture-resistant materials such as vinyl shutters or synthetic shade fabrics hold up best in these spaces.
Local Advice Makes a Difference

Frequently Asked Questions
What is the best window treatment to keep heat out?
Honeycomb shades are one of the most effective options because their air pockets insulate the window. The Department of Energy reports that tightly fitted cellular shades can cut unwanted solar heat by up to 60 percent. Shutters and solar roller shades are also strong choices.
Do plantation shutters keep heat out?
Yes. Closed shutters create a solid barrier between the glass and the room. Composite and vinyl shutters are a good fit for Florida because they resist heat and humidity.
Do blinds keep heat out as well as shades?
Not usually. Blinds leave gaps between the slats and add little insulation. They still reduce direct sun, but shades or shutters typically block more heat.
Can window treatments lower my electric bill?
They can help reduce cooling costs by limiting solar heat gain. Actual savings depend on your windows, sun exposure and how you use the coverings.
Which windows should I cover first?
Start with west- and south-facing windows and large glass doors. These openings usually let in the most heat during Florida afternoons.
