One-Way Privacy Window Film, 35.4x78.7"

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.
