I Tested And Reviewed 10 Best Blinds To Keep Heat Out (2023)

I recently purchased these blackout window coverings for my baby's room and I am extremely satisfied with the results. As a parent, I wanted the room to be completely dark during naps and bedtime, but I also wanted the option to let in natural light during the day. I had previously tried another type of window coverings with suctions, but they didn't stick well and were a hassle to remove when I wanted to let in light. With these blackout coverings, I found them much easier to use.

For the smaller windows that I don't frequently open, I used the sticky rounds, which worked perfectly. They were easy to apply and cut down to the size I needed. The material is lightweight, yet effectively blocks out the light. I also appreciated that they were easy to remove without leaving any residue or damaging the walls.

In our toy hauler, I used the velcro option for the windows with emergency latches. The velcro was simple to work with and provided the same blackout effect. It has made a noticeable difference in helping my child take daytime naps.

Additionally, I recently moved into a rental place where the natural sunlight was waking me up every morning. I was considering purchasing expensive room-darkening blinds, but then I came across these blackout coverings. They have been a game-changer. They are simple, effective, and require no drilling or installation. I was able to sleep in until 8:00 AM today, thanks to these coverings. They are also easy to take down when guests come over, making them versatile and convenient.

Lastly, these blackout coverings have been a lifesaver for my boyfriend who works night shifts. They create a complete blackout effect, allowing him to feel like it's nighttime in our bedroom. He can now sleep in on weekends without being disturbed by the blaring sun. The best part is that they can be easily removed without any residue or damage to the walls, making them perfect for apartment living.

I am extremely impressed with this product! It has exceeded my expectations in blocking out light and providing privacy. The installation process was a breeze – I simply measured, cut, cleaned the window, and stuck the curtains on with the provided Velcro patches. I was initially worried about not using an iron, but it didn't affect the overall process at all.

The room where I installed the curtains is usually warm and receives direct sunlight, but I have noticed a significant drop in temperature since using this product. The curtains have effectively reduced the heat by a noticeable degree. I also used them on a door window for added privacy, and the difference between the covered window and the uncovered one is striking.

In my daughter's room, where the window placement causes excessive heat, we decided to install the curtains in two panels. It only took us about 15 minutes to complete the installation, and the curtains can easily be taken down and reattached with the Velcro. Her room has become 15 degrees cooler and much more comfortable. The curtains block out light so well that I have to make sure to wake her up in the mornings.

I live in Texas, where the heat can be unbearable, and I specifically chose this product to address the issue of excessive light coming into my projection area. Not only does it darken the room, but it also helps to keep the room a bit cooler. This has made a significant difference in my comfort level.

I recently purchased this window film to add some privacy to my home office and I must say, I am quite satisfied with the results. The film effectively screens distractions from the neighborhood and provides the privacy I was looking for. I particularly liked the option of leaving a gap below the film so I could still see outside to my dogs in the yard.

The installation process was fairly straightforward. Following the basic instructions, I sprayed the window with slightly soapy water and then sprayed the smooth side of the film after removing the thin plastic. Although I didn't measure perfectly, I was able to eyeball the placement for the first side and used a blade knife to cut down the edge. There was a tiny gap of about 2 mm on one side, but it's not noticeable unless you are up close directly in front of it. For the second window side, I decided to trim it with extra film to cover both sides, but I found it a bit more challenging to cut exactly down the sides of the window. I had to peel away the edges, rewet the window and film, and then reapply for a smoother cling. However, I'm okay with the film being a bit imperfect on the edges, and with more precision and care, a more perfect application can be achieved.

As for the appearance from the outside and at night, I cannot comment as I haven't had the opportunity to observe it. However, I can say that the film has clung well after the initial application and is completely smooth without any bubbles. I found that using a new plastic putty knife as a squeegee worked great for smoothing out bubbles and excess water. It's also recommended to have a few paper towels on hand to wipe up any soapy water runoff.

In terms of value for money, I am impressed. I was able to cover my wide 70" window with less than a roll of film, all for under $10. While the film doesn't completely hide the items inside the closet, it does create a shadow effect, providing enough coverage for my office closet door. I have used other window films from Home Depot in the past, and I found the ease of installation for this particular film to be quite satisfactory. The adhesive being water-based makes it easy to apply, move, or redo if necessary. I do recommend investing in a brand new sharp exacto-type knife for more precise cutting. The recommended knife tool that comes with the product is flimsy and not recommended.

🔆With summer approaching, the sun is rising earlier and it becomes difficult to wake up without any darkness. If you don't have sufficiently blackout blinds, it's important to find a curtain or other fabric to block out the light.✅ Here, it's a plastic fabric that attaches directly to the window. This leaves no room for any sunlight to pass through. It keeps the room dark and cool, as the sun is blocked before it can heat up the air.✅ I chose this fabric for its thickness and I'm not disappointed. It's thick and doesn't crease. It won't deteriorate in two years. You just need to cut it to the right dimensions. A measuring tape is provided to measure your windows, and all you need is a pair of scissors to easily adapt it to your dimensions.✅ There are 3.5 meters, so it's possible to cover multiple windows.🎁 If you have aging Velux windows, it's also possible to replace the fabric.✅ Everything comes in a pouch that can be reused or simply used for storing the window covers during the winter months. The attachment is done with adhesive Velcro on one side. There are two types of Velcro provided. Either wide strips or just patches to stick where necessary.🏆 In terms of blackout, there's nothing to say, it's impossible for the sun to pass through. It's a plastic fabric, so it can't be machine washed, ironed, or have creases removed with an iron, so be careful when storing it. Otherwise, it won't be possible to follow the edge of the window the following year.✅ There's one side that is completely smooth, where I recommend placing the Velcro stickers for attachment. The other side is textured and less sticky. This side is less reflective but not completely matte either.✅ You can, of course, double it with a less dark and more aesthetically pleasing fabric on one side to maintain an appealing look in the room. It's also a product that will be perfect for covering vehicle windows to hide the contents from view.💦 My usage is a bit unusual: I actually use it to cover white rainwater collection IBC tanks to prevent the formation of moss inside due to sunlight.🙏 I hope my comment and photos have provided you with interesting information about this product.

I recently purchased two of these blackout shades for my sliding porch doors, and I must say, they have exceeded my expectations. My main purpose for buying them was to keep the park lights out at night, and they have done an excellent job in fulfilling that purpose.

Installation was a breeze. I measured and cut a few inches off the bottom to ensure that no light would sneak in from underneath. Using only 6 tabs across the top (none on the sides), I hung the shades with ease. I was initially skeptical about the durability of the velcro, as I intended to remove them daily, but to my surprise, they have held up exceptionally well. The shade material is lightweight, yet the velcro tabs remain firmly in place even after multiple uses.

I should have purchased these blackout shades years ago. They are a solid product that delivers on its promises. The light-blocking capabilities are impressive, and they have made a significant difference in my sleep quality. As a night owl, being able to sleep in late is essential, and these shades have made it possible.

One of the standout features of these shades is their construction. They are incredibly well-made and show no signs of shredding or tearing, which is a relief. The adhesive used for the velcro tabs is remarkably strong, so it's important to handle the edges carefully to avoid losing the stickiness.

If you decide to give these blackout shades a try, here are a few tips for optimal results. First, install them during daylight hours to identify any areas where light may be seeping through, allowing you to adjust the sizing and placement accordingly. Secondly, the package includes a generous amount of hook and loop tabs with strong adhesive. I recommend wiping down the window with rubbing alcohol before attaching the rough side of the tabs. When positioning the curtains, attach the soft side to the rough side of the tabs, reveal the adhesive, and carefully press the curtains onto them.

I also suggest leaving a little extra overhang on all edges to ensure complete light coverage. Cutting the shade exactly straight can be challenging, so having some extra material will help cover any missed gaps. Additionally, if you have any obstacles like air conditioner hoses, these shades are flexible enough to be custom-cut into an L shape to accommodate them. By using additional hook and loop tabs, you can easily wrap the shade around the obstacle, effectively blocking out any light.

The HTVRONT Window Privacy Film is an exceptional product that exceeded my expectations. As a first-time user, I was impressed by its ability to transform my glass windows into a shield against prying eyes. The installation process was a breeze, and the adhesive held up flawlessly.

One of the standout features of this privacy film is its elegant frosted design, which strikes the perfect balance between allowing natural light to filter through and providing the desired level of privacy. It truly creates a secret sanctuary within my home.

What makes this product even more appealing is its DIY-friendly nature. It is incredibly easy to cut and customize, making it a dream for DIY enthusiasts. However, I would recommend ensuring you have enough blades for your box cutter, as a dull blade may make it challenging to achieve clean cuts, especially when dealing with intricate angles.

In terms of sizing, it would be wise to purchase one size up to avoid the need for additional pieces. While the reviewer had to piece two films together for their front door, the product still delivered the desired results.

Furthermore, the HTVRONT Window Privacy Film boasts excellent adhesion, ensuring it sticks securely to your windows without any issues. This not only enhances its effectiveness but also provides peace of mind.

I recently purchased the smaller roll of this window tint and I must say, I am impressed. Even though my windows are quite large, I was able to partially cover two of them with the roll. The difference it has made in reducing the heat and blocking out the sun in my dining room is already noticeable. I am definitely going to buy a few more rolls to complete my project.

I decided to use this tint instead of installing blinds on my second-story window and I am very happy with the results. It effectively blocks heat while still allowing clear visibility and ample natural light to enter the room. The installation process was not difficult, although the instructions suggest cutting the film slightly longer and trimming it afterwards. I personally found it more effective to trim it to the exact size before applying it to the window.

The silver tint has a slight blue hue when applied to the window, which I find pleasant. It significantly reduces both heat and glare from the sunshine. The static cling film is easy to apply and remove, making it a convenient option.

I purchased this window tint specifically to block out harmful UV rays that were causing fading in a room with a lot of materials. The application process was incredibly easy and it adhered well on my first attempt. Following the simple instructions, I cleaned the window, cut the film to size, sprayed the window with soapy water, and then applied the film. I used a towel to remove any bubbles and flatten the film. While I took my time, using a squeegee would make the process quicker if I decide to use more of the tint. Overall, the film is as easy to cut as wrapping paper, but it is surprisingly durable once hung.

Even if you are not particularly handy, you can easily install this window tint. The tools you will need include a sharp box cutter with a fresh blade, a spray bottle (or a temporarily emptied spray fabuloso bottle), and a squeegee. I used this product for a sliding glass door that faced a bright rising sun every morning, causing unbearable glare on my TV in the adjacent living room. This tint solved that problem without sacrificing my view. The installation process is similar to applying a protective glass screen on your phone or a flexible plastic screen on a smartwatch. It is crucial to thoroughly clean the window to avoid any dirt or dust affecting the final result. I found that the first window had more dust, resulting in small bubbles that were difficult to remove. Therefore, I highly recommend ensuring a clean surface before applying the film. Additionally, it is important to cut the film slightly larger than the window and use plenty of soapy water before using a squeegee to ensure a smooth application. Before trimming off the excess, make sure to use a brand new exacto knife blade for quick, easy, and consistent cuts.

In terms of privacy, the pictures provided by the seller are accurate. During the daytime, it is not possible to see inside the room, although the film can appear slightly unattractive from the outside. However, visibility from the inside looking out is maintained, albeit through any dust that may be present.

The black-out sheet with Velcro attachments is incredibly easy to use and provides excellent functionality. I recently used it on a wide window with two panes, one of which slides over the other. Despite the attachment, the window can still be easily slid open and closed. Additionally, the sheet can be pulled back from the window pane to let light in when needed, which is a great feature.

Compared to other blackout sheets that I have used in the past, this one is far superior. The previous ones I used would peel and lose their adhesion over time, but this sheet with Velcro attachments stays securely in place. One helpful tip is to purchase a larger size than you initially think you'll need. I was able to cut the sheet to fit the edge of the glass perfectly, with enough extra material to extend it onto the frame. This ensured that no light came through, providing complete blackout coverage.

I also used these blackout sheets in a room with glass in the door to enhance privacy for our summer guests. The sheets are simple and straightforward, made of blackout material that effectively does its job. The creases in the fabric do not come out, but for me, that is not an issue. If desired, the fabric could be lightly ironed with a towel or fabric protection to remove the creases.

I also added these blackout sheets to the long windows in my child's room. I flipped them to have the black side facing out since I was not concerned about heat protection, and the black color looks nicer from the outside. In the room, the blinds cover the silver side of the sheets, providing a more aesthetically pleasing look. The window photos I took clearly show the difference between the window with and without the blackout sheet.

Installation of the blackout sheets was incredibly easy. I appreciate that you can cut them to fit your specific window size, ensuring a perfect fit. The sheets completely black out my baby's room, creating an ideal sleeping environment. I have taken them up and down multiple times for changing and playtime, and the Velcro attachments have held up excellently.

Upon setting up the sheets in my windows, I immediately noticed a difference in the room's temperature. It felt noticeably cooler, which is a great bonus. The material is easy to cut but feels sturdy enough to stay in place once installed. The package also includes enough Velcro sticky pads for several installations, which is convenient.

I recently purchased this blackout curtain and I have to say, it exceeded my expectations. The installation process was a breeze compared to other alternatives such as static cling options or curtains. Not only was it easy to install, but it also proved to be more effective in blocking out light since it covers the entire window and reflects more light.

I compared this blackout curtain to regular blackout curtains by placing them side by side on my windows. The difference was noticeable, with the blackout curtain providing better coverage and helping to cool down the room. I did face a minor issue with creases, but it didn't affect the functionality of the curtain. I simply pulled it tight when sticking it to the dots on the wall, and the creases were not a problem.

I was particularly impressed by how easy it was to cut this thin fabric without causing any fraying. I used scissors, an exacto knife, and a sliding paper cutter, and the fabric remained intact. The adhesive dots that come with the curtain are very sticky, but I was able to reposition one that I accidentally placed in the wrong spot on the painted wall without causing any damage or loss of adhesive power. The Velcro is also of high quality and sticks together tightly.

As someone who enjoys taking naps during the day, this blackout curtain has been a game-changer. It completely blocks out sunlight, allowing me to have a peaceful sleep. The photos I have included were taken at 10 AM, and you can see how effective the curtain is at blocking out light. Not only does it block light, but it also helps in keeping the room cooler.

I appreciate the inclusion of Velcro and little tabs to apply to the walls. The tabs are particularly useful as they do not damage the walls when removed. This attention to detail adds to the overall quality of the product. I would highly recommend purchasing this blackout curtain if you are in need of a reliable and effective solution for blocking out light.

I also want to mention that I have used this blackout curtain in combination with soundproofing over the window, and the result is truly blackout. We cut the curtain slightly longer on both sides, which turned out to be helpful in achieving a perfect fit.

In addition to its light-blocking capabilities, this blackout curtain also has sun reflective material on the opposite side. This feature is especially beneficial in keeping my sunroom cooler, as we use it as a playroom. I am extremely satisfied with this product and it has solved my problem of finding a suitable option for my sunroom without the need for curtain rods or suction cups.

The only suggestion I have for improvement would be to include more window clings and equal amounts of Velcro and window cling double-sided adhesive. While I had enough Velcro for my needs, I was left with limited window cling, which made hanging up the last piece a bit challenging. Overall, this blackout curtain has been a fantastic purchase and I highly recommend it. Thank you for providing such an amazing product!

I was initially hesitant to purchase this product due to the negative reviews I had read. However, I decided to take the risk and buy it anyway. And I must say, I am extremely satisfied with this blackout curtain. In fact, it has surpassed my expectations and is by far the best window covering I have ever used.

Contrary to some reviews, I have not experienced any issues with the double-sided sticky discs. They have been holding up perfectly for a week now, even on my southern-facing window that receives sunlight throughout the day. As a result, my room feels like it's the middle of the night at all times.

To ensure proper adhesion, I recommend cleaning the window with alcohol before applying the product. Additionally, I suggest buying the curtain slightly larger than your window size (e.g., a 12×12 window should be cut to 13×13) and using an xacto knife for precise cutting. By following these simple steps, you will be able to enjoy uninterrupted sleep during the day.

In addition to its blackout capabilities, I noticed that the curtain also helps keep the room cooler. I believe this is intentional, as the side facing out is a shiny gray material. It's lightweight yet durable, similar to the material used for tents. When installed correctly, absolutely no light will penetrate through.

I highly recommend this product, especially for those who work night shifts and struggle with sleep during the day. I have personally found nothing better and will no longer be searching for alternative solutions. It has truly been a game-changer for me, allowing me to sleep a solid 8 hours despite my graveyard shift.

Update: After a month of use, I can confidently say that I have encountered zero issues. My room remains the coolest and darkest in the house, even during a recent heatwave. The curtain has held up exceptionally well and shows no signs of deterioration. I continue to highly recommend this product and have no intention of taking it down anytime soon.

Second Update: It has now been several months, and I am pleased to report that I have experienced no issues whatsoever. The curtain is still as strong as ever, showing no signs of wear and tear. I am convinced that this is a top-notch product, and I highly recommend it. I have no doubts that it will continue to serve its purpose effectively, and I anticipate it lasting for a long time.
