If you want to make your home cooler, the best heat control window films can significantly reduce the degree to which the sun warms your space. Top-rated films on Amazon can block up to 95% of UV rays (or higher!) by providing an extra layer of insulation to block out the sun, and many can also prevent glare. Heat control options also tend to act as
privacy window films as well, shielding you from both the hot sun and the eyes of your neighbors, but unlike heat-blocking thermal curtains, they may also let in some light. Before you shop, consider what levels of heat control and privacy you'd like, and think about how much natural light you're willing to sacrifice in the name of cooling your space. What To Consider When Shopping For The Best Heat Control Window Films
While it’s true that blocking the sun — both its light and heat — is the way that heat control films work, styles with a tint or frost can let in some natural light while providing some privacy and heat control. One-way privacy films shield you from sight during the day without interfering with your view out the windows, as well as blocking heat, though it's worth noting that the privacy features don't work after dark. Some window films are even decorative and can enhance your windows with an attractive pattern. Like
blackout curtains, blackout window films will totally block the sun, but they’re often colored black and can get hot to the touch; look for options with a white exterior to truly keep things cool.
Most films either adhere by using either an adhesive or static cling. Both types are effective, but static cling films are easier to remove and reapply, and they don't leave behind any messy residue. However, they may peel in intense heat. Adhesive film is a more heavy-duty option and ideal for windows that see a lot of moisture or extreme temperatures, such as bathroom windows. When using adhesive film, keep in mind that removal and repositioning during installation can be difficult. Window film comes in a variety of sizes that can be cut to fit your windows, so try to choose the film closest to your window size to reduce the amount of trimming you’ll have to do.

Scroll on for my top picks for the best heat control window films to upgrade your windows, cool down your space, and save on energy costs. Oh, and pro-tip — be sure to stock up on chemical
window cleaners, cleaning cloths, and squeegees, too, since window films should be applied only to clean glass and are often smoothed with a squeegee during application. 1 A One-Way Heat Control Window Film
mirrored window film installs via adhesive to provide permanent heat control and protection. When applied, the film blocks up to 85% of infrared rays (and up to 97% of UV rays), so you can say goodbye to excessive heat and UV exposure in your sunniest rooms. The film even blocks glare up to 10%, making this film a true lifesaver for those who spend time in sunny homes.
In addition to heat control, the window film also provides daytime privacy without blocking your view of the outdoors. The film has a mirrored appearance when on the outside looking in, but you can still see through it from the indoors. Don’t get
too comfortable with that privacy, though — at night, if you have the lights on, people will be able to see inside. The window film comes in a roll with a dozen available sizes and four tint options: black silver (pictured above), blue silver, brown silver, and silver. Positive Amazon review: “Works really well at keeping the heat out in the summer, our bedroom faces the sun at evenings and was hard to keep cool but now after installation of the tint it stays alot cooler.” Application type: Adhesive | Available sizes: 12 2 A Fan-Favorite Iridescent Heat Control Window Film
If you want a more decorative look, this
Rabbitgoo window privacy film is a great option — and with over 59,000 reviews on Amazon and an overall rating of 4.6 stars, it’s clear that people really love it.

Application and removal should be super easy since the film attaches via static cling and doesn't require the use of glues or adhesives. You can buy it in a variety of different sizes.

frosted window film gives your home a chic look while adding a layer of privacy — and blocking out heat, of course. According to the manufacturer, it provides heat insulation in the summer and heat preservation in the winter to help lower your energy costs. This static cling film can filter out up to 90% of the sun’s harmful UV rays and 86% of heat. But that’s not all it can do — the frosted tint prevents the neighbors from peering into your home, making it easy to enjoy some glare-free sunlight with the blinds or curtains wide open.
The window film attaches via static cling, which means installation is easy and you can adjust or remove the film any time you want. It’s available in two frost finishes, so you can pick the one that best matches your space.
One reviewer wrote: “I’ve used other brands [...] and they slip off the window very easily. This I bought for our garage window which faces the street. My husband works from his garage and there are lots of valuables that are visible from the street. We are very happy with the privacy this provides as well as the added benefit of cooling down our garage in the afternoons when the sun hits this window. Very happy. Very easy to install. No bubbles. Good cling.” Application type: Static cling | Available sizes: 6 4 A Blackout Heat Control Window Film
Blackout window films can be great for blocking heat since they block sunlight entirely, but they can also get pretty hot to the touch since they’re typically made of black material. Not so with this
blackout film, which has a white exterior that reflects UV rays and doesn’t get as hot. The film, which still appears black from the inside, blocks 100% of sunlight, and users report that it’s very effective at keeping their homes cool and dark.
The blackout film is really only a good pick for you if you’re trying to achieve total darkness, but it’s a great cooling option for anyone who really wants to totally keep the sun from coming through the window. It applies to glass via static cling.
One reviewer wrote: “Works so good. I’m a really light sleeper and these work basically as blackout blinds. I’m not handy around the house but installation was fine — I just followed the instructions and it worked. Definitely highly recommend for light sleepers or people sensitive to light. I also think it helps with the heat in the summer.” Application type: Static cling | Available sizes: 9 5 A Heat Control Window Film That Looks Like Stained Glass
