BDF S2M Window Film Clear UV Blocking - 24in X 12ft

The most challenging part was getting us both up the ladder while holding the 90" long piece without having the film adhere to itself. Other than that, installation was a breeze. I highly recommend watching their video tutorials on Youtube. It breaks down the entire installation process in a 5 minute video as well as provides key highlights in individual mini-tutorials. My best piece of advise is to spray A LOT of water. They said it best, "There is no such thing as too much water, but there is such a thing as too little." The water makes it super easy to move around and position the film onto the window so you don't have to be an expert to do it if you use enough water. More importantly, the water helps to prevent the film from sticking onto itself. If it sticks then that piece is done for. To break down the quality of the product - it looks phenomenal. You can not notice that there is a film there. Only way our guest would know is if we told them. My wife and I can notice the difference between a window with a film and a window without. The windows with the film have a bit of a oily water sheen to it but it is only barely noticeable and only when there is something solid behind it like a tree. If looking into the sky, you can't see it. The product comes with everything you need minus the spray bottle and tape measure. It comes with a knife which was surprisingly very sharp and great quality. To put the knife and perhaps the overall quality of the product into perspective, we first threw the included knife aside and opted for one of our Olfa knives. Even if it is a little dull from cutting through foam for cosplay crafting, surely a dull Olfa knife is better than what they threw in with the film, right? Wrong. The Olfa took my wife several passes and all it did score the film. I suggested using the one provided with the film and it cut through the film like butter on the first pass. Maybe I am putting too much meaning behind their quality of the knife they provided or maybe it's the quality in the details that matter most and the manufacture of this film understood that. I didn't do a temperature test but maybe I'll update this review to reflect on if we noticed the room being cooler. Temperature isn't so important to us since our A/C unit blows absolutely freezing air directly at us. The reason we installed the UV film is because of all our artwork we have hanging on our walls. We have quite a few very expensive and meaningful pieces and we would like to see it preserved as long as possible. This would be just additional step we could take to preserving our original art pieces while improving our household. All for less than $100. Great value! Perfect for those who are now working remotely from home due to COVID-19 and noticed that there's a lot of sunlight hitting the artwork!

I saw the other reviews complaining that this didn't appear to be block UV. It does, just not 99%, more like 80%. See the pictures for before/after on a sunny day. This was fine for my uses. The reviews using the purple test cards are generally mistaken -- those cards are checking for germicidal (high) levels of UV within a very narrow wavelength band and usually provide only a yes/no answer, so are not good for testing broad spectrum UV performance at different levels of intensity. Similar goes for using UV-reactive money. The meter in my pictures reports UV index, which is designed for wavelengths that cause tanning and skin cancer, but the scale is linear so dropping from 6.0 to 1.0 is indeed 80% lower. On a 20" wide window it was easy to install on the first try, even with zero prior experience with window films. Just drench everything. I actually dropped it on the floor once because it was so slippery with all the water.

The videos make this product appear easy to install. Not even close! This film is: -very easy to kink -not pliable -extremely tacky no matter how much soapy water you spray on the film and the window -impossible to move or align the instant after it makes ANY contact with the window -again, no matter how soaking wet the film or the glass may be, it will stick for good. I have a great deal of home improvement and handyman experience. I believe in doing things well, and lucky to have an aptitude for it. I always read instructions, often more than once, and watched the manufacturers video twice. Looks like putting up wallpaper, no problem!? Wrong. I've done plenty of wallpaper over the decades. Never one problem. Installing this film (with adhesive, apparently water activated) is like putting up magnetized wallpaper using super glue! If the initial contact is not perfect in every way, forget about it! There is no chance of tweaking or adjusting after initial contact! The adhesive is amazing in how fast and strongly that it sticks to the window even with an awful lot of of soapy water on the glass and the film. I followed the instructions to a T! The video is very misleading. I was putting it on a 32" x 72" slider window. It should be easier on much smaller windows. But I still don't recommend this product at all. It was a great waste of time!

Es un artículo muy útil en climas extremos

Typical of 1960’s ranch homes, our kitchen, dining and living rooms face the street out front. With our older windows, we were on display, but this film added a mild reflective effect and it’s no longer easy to see us inside - just what we needed!

Edit : After having this "uv filter" up for about a month, I noticed the consistency of my nail gel polish changing (I own a nail salon with a medium size window). I made a UV gel curing test, letting the gel sit on my desk on a closed day where no lights were on. When I came back (mid day) the gel let on my desk had cure. So if you are looking for something that filters UV so you don't ruin thousands of dollars of products, this is not it. I should have done the testing on the same day I set it up, lesson learned. Installation : Following the instructions to a tee is key here for an easy ans flawless installation. Make sure the window and the sticky side are fully covered in soapy water. I installed it alone, was easy, did not have any issues. I left a millimeter between the film and the glass edge so the water would come out when I squeegeed, otherwise it made a water bubble in a corner.

It was good ,thanks

I am unable to tolerate any UVA/UVB radiation at all. This makes life very limiting. I used this on my car windows. Front windows by law must have UV protection but I added this to the whole top 10 inches. I also did the side windows. I gave 4 stars only because it is not at all easy to install. I don't think the product is at fault really but it is absolutely not as easy and the window cling sun protection. It also left bubbles no matter what I did and I have used window protection for years. I applied and reapplied with fresh product with the same results. That said, if you can tolerate some imperfections or are doing easy areas this is amazing! I can get some of my life back and not feel like I need to live in a cave. I highly recommend this to anyone what has issues with the sun or it's rays. I even put some of this over lightbulbs (not encased) and it is perfect there too. My health is steadily improving.
