One Way Privacy Window Film Sun Blocking, Heat Blocking Window Tint for Home See Out But Not in, Static Cling & Anti UV, Black-Silver,35.4 Inch x 78.74 Inch

Update — I did all of the windows on the porch, and the ambient temperature dropped significantly. I have one of those temperature infra-red tools and aimed it at windows on another part of our place that was getting the same sun at the same time as these windows. The temperature of the glass in the evening western sun was 124 degrees (just sitting there baking and all of that heat was transferring inside), and that part of the building is really hot inside. I then aimed the reader at the windows with the film, and the glass was reading only 92 degrees. (Keep in mind that the film is on the inside of the glass, so the sun is still heating up the glass, but that heat is reflecting back out, so the inside of the glass was only 92 degrees.)This means there's about a 30 degree difference between the two areas, and the only difference is one set of windows has this film on them and the other set doesn't.What that has meant is that I'm running the a/c a *lot* less and it's actually getting too cold in there sometimes… in July… in New Orleans. So this film has really impressed me.I like that my neighbors can't see in during the day, also. There is some visibility at night from outside, but that's marked clearly on the packaging.Read further for the original review and tips.We have French doors in our sunroom / dining / living area here in New Orleans, and it was like an oven. The (big) mini-split wasn't even keeping up, and it was miserable. We are not able to change the windows due to historic requirements, and I didn't want to have to close the curtains all day and miss out on the view. But the sun was baking my plants (not to mention us).This film really freaking works. I tested it out on the side that gets full western sun first—it's blazing hot there, and the drop in temperature was significant. I'm adding the film to the rest of the room and now the A/C isn't having to kill itself—it's staying comfortable, even before I finish the rest. (The long wall gets morning sun, which is also an issue. I feel like the room will be very comfortable once it's all done.)TIPS: I struggled a little bit at first getting the film to lay flat, but the instructions literally say, "more water, more better" (lol), and honestly, that's true.When you clean the panes, make sure you dry them really well before adding the water and film, because if there's window cleaning product still on there, you may get bubbles.While the seller does include a little (decent) utility knife and water spritzer with each bottle, if you're like me and doing a bunch of windows, make your life easier and use a larger spray bottle and really good utility knife—the install went smoother / faster when I switched to better tools. I think if you're just doing a couple of panes, then what they include would be fine.I didn't like the little plastic squeegee sticks they included, mostly because they're skinny and harder to hold. I purchased a cheap decoupage squeegee from Amazon (I think it was maybe $4 for two) and it has a nice pad on the grip and is much much easier to use. Again, if you're only doing a couple of windows, then what they include may be enough.If you get bubbles, it's easy to lift the film, re-spray the water and then lay it back down. I found that (so far), it's clung really well. Sometimes I'll have issues on the very edges (not sure why), but a quick partial lift of the film, more water, and then it goes back down easily.The only thing I dislike about it is kinda silly — there's a clear film that you pull off before you install. (It doesn't affect the film's ability to cling—I think it's just there for protection until you're ready to install, maybe?) There's a tab at the top of the roll to separate that clear protective layer (and it's easy to pull off), but once you've cut the film into panels like I had to do, each next "panel" didn't have a tab (of course) and getting that film to separate from the clear cover was kinda a pain. (Like opening medicine tablet covers that just.do.not.want.to.seperate.) Lol, not a bad thing, and there's probably a simple fix I'm overlooking, but for all of the positive, I didn't think this one negative was enough to ding it in the rating.In my photos, the long wall shows you the color on the right as the "before" and then color on the left as the "after" so you can see how much the film tints your view. I like it—real life looks better than the photo does. (I'm working left to right in the room, hence the order you see in the first photo.) The second photo was taken with the western sun beaming in, after the film was installed.Hope this helps.

Designed to cool internal room. Not privacy. Took some time to work bubbles out. Comes with plastic stick applicator, spray bottle, and small utility knife inside the cardboard tube. Found it best to clean the window. Let dry. Then soak the window and back of film with a washcloth prior to applying. Run the applicator back and forth then work the bubbles. out. Also, be prepared to have some patience.

Very easy to apply but cutting the edges was a little challenging on the first window. After doing the first window, all the rest looked so much better and I was able to cut the edges more precise. Unfortunately, I ran out of the window film but ordered more to redo my first window.

There was a slight learning curve to use this product but I'm a senior citizen and I managed to do it by myself. So I think probably anybody could, lol. I wanted to put it on because I have this ratty cat tree in the front window that my senior cat uses, and I just got done doing a bunch of landscaping. So I wanted to hide what was actually in that room!The most important aspect of using this film : it cut the temperature in the room within minutes of application. It's probably a good 10° cooler in that room, then it was prior to putting this on the windows. I highly recommend it.Clean your windows thoroughly.Use plenty of water on the window, while you're applying the film and it's easy enough to reposition it if you don't get it right. Also for me, it was easier to cut it slightly larger than the window. And then use an exacto blade to trim down the inside to fit perfectly rather than measuring it before application.

This worked wonderfully for privacy, I can keep all my curtains open all day and not worry about anyone seeing in. You do have to pull them closed at night though. I have large windows and still found it easy to apply.

I bought these for my office window to block the glare on my monitor! It worked and so far has held up!

This material was thicker than expected. The thicker material was difficult to work with. The worst part is when is got warm/hot it shrank. So now there is an 1/8 to 1/4 inch gap all the way around the window. I will be buying a different brand and redoing this because since shrinking it looks terrible.

Gave it a 4 because the bubbles are so hard to get out!It was a little harder to get up than their other products.Looks good, keeps the sun from glaring in.Would purchase again.Use lots of water and it stays up great. Also keeps the dogs from scratching the window.
