Coavas One Way Privacy Window Film, Sun Blocking Reflective Window Film See Out Not in, Heat Control Window Tint for Home, Anti UV Static Cling for Windows Office Door (Black, 17.7 x 78.7 inches)

I was a bit skeptical about these when I read some of the reviews that said this was hard to apply, but I figured for $10 bucks a pop, I would give it a try. The quality of this vinyl is very good. The vinyl is much thicker than I expected, and the pattern is actually textured onto the vinyl. I have two large windows on my back doors, and I have had a neighbor snooping around behind my house, so it was time do to something. This was easier to install and more affordable than blinds or curtains. I followed the directions carefully, which included removing the protective plastic sheet from the inside of the film, cleaning the window very well beforehand, and using water spray on both the vinyl and the window before applying. This process was very easy, but do it when you have time to be patient.My tips for installation.* I had also purchased a special felt squeegee kit (HTVRONT brand) for about $9 with sprayer bottle and exacto knives to help with the installation, and that made it much easier--worth the money to get that. I know some others have mentioned using a credit card as a squeegee, but I think it would be more difficult considering the textured pattern on the vinyl.*Measure the window to determine the size you need and then cut the vinyl before removing the protective film. My only complaint about this product is that there are no gridlines on the back to facilitate straight line cutting.*If the vinyl isn't where you want it to be, you can reposition if you have used a lot of water, and if not, remove it, add more water, and reapply.*Use a lot of water spray on the window and on the decal. If you have a decent squeegee, and I found this worked great with a felt squeegee, you will remove all the excess water. Once the vinyl was positioned where I wanted it on the glass, I spent a lot of time squeegeeing from the center of the vinyl to the outside, and then I would use a towel to wipe away the water that came out from the sides. In this way, I was able to remove ALL bubbles under the vinyl. It takes a bit of time but it totally worth it.*Before you finish squeegeeing, try looking at the vinyl in different lights and angles so you can find any bubbles you didn't see initially. Then squeegee them out.From start to finish, including measuring and cutting, it took me about 45 minutes to install these on the two windows. Several days later, even with crazy temperature variations outside, it is stuck fast with no peeling or bubbling and looks fantastic.What I like the most about this privacy solution is that if I change my mind about having that window covered at another time, I could easily remove the film.Highly recommended.

Got these to help keep a room that is east-facing cool and they work like a charm. Pretty simple to install, be sure to use a spray bottle to wet the window for the easiest installation. They work great for keeping people from seeing into the house as well. Guessing they will help with minimal heat loss in the winter, but it's still summer and super hot here.

Installation was conceptually easy. For larger windows it helped a lot to have a second person. The end result looks very nice.The marketing claims that it reduces 90% of UV light. That sounded way too good to be true. So, I measured it myself. I found a 36% reduction, at least in the 405 nm +/- 3% range. This range is important for those working with UV-curing resins.

Works great..!Definitely helps keep the temp lower.I live that I am able to have privacy but still be able to look out the window. That’s important to me.Peels easily and it’s easy to apply, make sure window is clean and wet when applying.It's lightweight and the color was as described.The only downside is that it doesn’t provide privacy at night when the lights are on. You can see through if the light is on, so keep that in mind. Still, it’s a great solution for daytime privacy.

I used this product on one side of a sliding door. This product is thicker, much like a tarp, which may translate into better insulation and ray deflection. I had recently worked with two competing products, one thinner and one thicker, and this is superior to the competing thicker product and on par with the thinner product. Both thicker products darkened the incoming light, it's a matter of your preference (I had not thought about that ahead of time, but would recommend doing so). Surprisingly, this product had no problem with curling (pic 1), making it easy to work with, no wrestling or having to roll it the opposite way and using office clips to keep it that way, at least overnight, like its competitor!There are no tools included in this one as the thinner option offers, but it helped for me to have done three pairs of windows before this one in terms of the amount of time it took.My modified instructions are: (1) Decide a large smooth surface where you’re going to measure the material, and sweep its dirt off first. I used a laminated wood living room floor near the target window. (2) Measure the window, ideally with a long straight edge (pic 2, I forgot about that straight edge before!) that's as long as one of your dimensions; (3) Clean the window(s) you’re using this product on; (4) Gently lay out the product. You will only need one or two heavy things to weigh down the edges due to this product's minimal curling. A floor lamp or overhead light will help you see your marker marks. Using an erasable marker, with measurements a marker width wider than what you came up with in step 2, mark the product for the shorter length cut (typically to the length of the slider in my case). It's easier and thus a good morale builder. Cut that side, I used scissors. (5) For the longer edge, assuming that your window is narrower than this product, pick which side (left or right) you're going to remove the excess off of based on which has the most defects (pic 3). You may need a soft sofa, chair, or person to help you do the longer cut, for laying the product on as you cut your way through it. (6) Optional: wipe off your marker marks. (7) Hold what you cut on the window (dry) that you’ll be putting it on for checking your accuracy. If it’s slightly off, use that on the top of the window (have the “off” part where it would be least noticed). With this product, due to its thickness, it's best to cut the extra, it's best to use scissors. (8) Clear out the area in front of the window. Fill a spray bottle with water and lotion (not detergent), mix well so that it’s relatively clear. Place a towel in front of the receiving window, and generously spray the receiving window. (9) Peel off the back of the product- they include tape, fingernails worked fine for me, whatever works! This will be challenging for a sliding door window due to its length. (10) Hold the film over the towel that’s near the window and generously spray the side you just exposed. (11) Apply the product to the top of a sliding window and let it hang down. (12) Wrap a squeegee with a washcloth/hand towel to avoid scratching the product and work your way down to first remove the bubbles and water and second to apply the product. Don't let striving for perfection get in the way of very good, there's usually no significant difference (pic 4, after I tried it a second time). With this type of product, as long as you cover 99% of the window, you're good! (13) Press around the edges to force the curl away from the window. (14) Due to this product's thickness, getting as close to size is preferable. Scissors worked better for me than a utility knife, for you can easily make a mistake with the latter, including on the frame if it's made of vinyl. (15) Relax, you did it! Okay, one!Darkness: noticeable difference. That was my primary motivation for doing this work.Heat gain: the thicker material seems to make a difference. I put this product on the westernmost sliding door window due to it getting the stronger afternoon rays.Big suggestion: don't order more than one of these products, especially if they're the same width, at the same time OR label them when they come in. I did not, and this product ended up on a different window than it was intended, but on the other hand was much, much easier to work with and install than the other one, which ended up in, fortunately, a more obscure location.
