Coavas Total Blackout Window Privacy Film 100% Light Blocking & UV Protection, Static Cling Frosted Privacy Cover No Glue Heat Control Room Darkening Shade for Bedroom, Nursery,17.5 x 78.7 inches

Wonderful film and easy to work with! The glare from my living room window made it really hard to see the tv, but with this film it really darkens the room. I used it on my upstairs windows as well to reduce the heat in the rooms. Still lets in light but really reduced the heat coming in.

Great window film for day time privacy, room darkening (mild to moderate) and energy savings! I bought this film for a west facing bedroom that gets a ton of sunlight and heat in the summer. It is great! When the sun is shining it is like a mirror finish with total privacy. Be aware that the way this particular film works is based on the light, so if the room has more light than outside it does not offer privacy. I knew that going in so I was okay with this. Also, different reflective films block the sun more or less, I have ones that block less on my west facing doors, but I wanted darker (while still being able to see out) for this bedroom window, so I chose this tint. The application is easy, but a few tips will help a lot. First, make sure your window is completely clean. Then use a lot of soapy warm water. I apply it with a rag. I find it is better to deal with a little water mess than not have good adhesion. I use a utility knife to trim and a squeegee to help get air bubbles out. Small areas (like half a double hung window) will be easier to get the air bubbles out than large areas (like a picture window). Be patient. Also, if you are using a large film, it can be helpful to have someone else position it, but not impossible. Use tape to pull off the clear film (or cut off the edge if you bend it to get the film off). Make sure you apply the film to the inside of the window. Make sure the reflective side faces outside. This brand worked very well ( I have used many) and had just the right thickness. There is customer support and videos if this is your first time doing this sort of thing. I love that there is no adhesive, it works with static cling (I do recommend using soapy water) so there is no commitment. Great purchase!

Difficult to install in a way that I couldn't see a gap between the film and edge of window pane, although care was taken, instructions followed and gap was small. I could see it and did not like it. Took care to squeegee out the bubbles, with soap/water mix and still bubbles remained. Even where it was bubble free, clarity was not as good as I expected, to photograph birds without them seeing me move around inside. UV sun blockage was great though. If that and privacy are what you're after, I assume most people looking at this are, that part is really good. I'm admittedly a perfectionist so the little things bother me. Since I have already installed this and obviously can't return a cut product, I will leave it on for awhile and see if I feel differently later but for my immediate expectations, this did not meet them. But it DID block sun and give the privacy it advertises.

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.

Got this because of soaring temperatures and power costs. So far it is keeping my south facing rooms much cooler (and lessening the severity of my migraines). Rooms are a little darker because of the film but they were far too bright for me before, so this is more livable. Some corners didn’t stick well and had to be taped to stay in place, but that’s ok.

The privacy film really cut the heat coming in from the sun through my window in the laundry room that is the only room I do not have insulated windows in. As for privacy you cannot see in from outside but you can see out. I ordered the wrong size wish I’d went bigger. Easier than a thought to install. Recommend highly.

The only source of daylight in our main living area was our front storm door. Unfortunately, it's south facing, and this lets in a lot of heat, and salesman and such could see us moving about the inside of our home. I chose the silver film and love the heat deflection and privacy it offers. The second, exterior shot I provided shows the door on a cloudy day and with a lot of inside lights on, you still can't see through the film, not until it's totally dark outside. I've used these sort of films in every house I've ever lived in and never have found one as difficult to apply as this one though. No matter how much I tried, I couldn't get all the bubbles and imperfections out of the film. They are not really apparent from indoors, but you can see them very clearly when you are outside. Luckily, I'm retired now, and I've hit my don't give a c*** about perfection phase of life, lol. I have my privacy and we are not baking, so I'm happy. But if you want perfection, I'd suggest going with a higher priced option.

Delivers what it promises with significant temperature reduction on sound facing patio doors with the added bonus of privacy in daytime. Would have given 5 stars if it came in typical patio door widths!

Relativamente facil de instalar, la película es un poco gruesa por lo que cuesta cortar los pequeños detalles, drnn tener cuidado cuando ya le sacaron los residuos de agua pues aún se puede mover. El decorado es muy bonito no se transparenta mucho por lo que si la van a instalar en lugares con poca iluminación deben tener en cuenta eso.

Looks great and super easy to install. Just cut to size, apply some water on your window, stick the film on and trim edges with a craft knife. Took the best part of 10mins and completely transformed my kitchen window.

Great product, fairly easy to use but can become a bit fiddly to get the backing plastic off. I've used it in the front room with about 1cm left of the window framing the frosted area (so we can still kind of see what's going on LOL) and the only thing that would make it even better would be to have a white backing paper with straight lines every 0.5cm (a bit like the sticky plastic for schoolbooks) so lines would be very easily cut straight. But with the nice geometric pattern even the wobbly lines are barely noticeable. I would definitely recommend this!

Looks fabulous!! great value for money and relly changes the look of the room, lets plenty of light in. East to fit, just be patient and follow instructions

Very impressed, looks good ( better than previous nets) easy to fit with care
