Description

BDF is a premier window film company that offers a wide range of high-quality and stylish window films to customers. We have various types of window films can provide practical solutions for window-related needs, such as sun control, enhanced daytime privacy, security, decoration, opacity, and protection from UV rays. Our window films in various colors and appearance can add elegance and sophistication to your home or office. An excessive amount of water solution (16 oz. water + 8 drops liquid soap) will make handling the film easy. Spraying soapy water on the adhesive as you pull off the liner will prevent the film from being too sticky. To remove the liner, use two pieces of tape, attaching them to a corner (one on each side, facing each other). Press the tapes together, and then slowly separate the two pieces. The films are installed inside unless the film is specified as "exterior film". BDF's Natural 35 Sun Control and Heat Rejection window film not only gives your window a tinted look but also provides effective heat rejection. With a mildly dark, black tint, the Natural 35 heat rejection film still adds a decent amount of shade to your window, but it lets in a good amount of visible light. If you want an excellent combination of heat rejection and light exposure, the Natural 35 will make a great choice. Films are made in Korea. BDF NA35 provides various functions such as heat control, reducing cooling cost, and blocking UV rays while letting in a good amount of light. The medium black tint of the NA35 helps reduce glare. The number "35" in its name refers to the fact that it is rated to transmit about 45% of visible light. The NA35's black-tone nature gives it a good heat-rejecting rate of up to 42% that keeps the interior of your home or office building nice and cool. By maintaining your room at a cool, moderate temperature, resulting in lower cooling costs, you can promote a more environmentally aware lifestyle by reducing energy usage and help create a greener world. The NA35 achieves reduction of incoming heat with a balance between letting light in and having some shade. Because of the medium shade that allows more light to pass through than other darker films, the NA35 provides an excellent view out the window with a mild level of view-shielding. This makes the NA35 a great choice if some sunlight exposure is desired and privacy is not the primary concern. Good for homes and office buildings that are directly exposed to the sun which is the source of the UV rays, the NA35 window film provides an excellent UV blocking barrier. Being exposed to UV rays can cause skin problems such as premature aging skin and signs of wrinkles as well as eye problems. The NA35 film rejects about 99% of the UV rays, helping to reduce fading on your precious furniture, pictures, or other UV-sensitive belongings. More and more dual pane windows are installed in the houses around our neighbors, and BDF NA35 film is the perfect solution for these dual pane windows. Due to the nature of its medium tint, BDF NA35 film holds on to less solar heat. With the lower heat absorption, the NA35 will keep the dual pane window cool enough to remain stable. Our products come with tools needed to get your job done, and an installation guide is included to help you with a smooth installation process. With the right amount of care, practice, and patience, both installation and removal of the film should be simple and easy. Whether your windows are small, big, wide, or narrow, our products come in a variety of sizes to suit your individual needs. It is usually recommended and necessary that you have more than enough film to cover the window. CLEANING THE WINDOWS It is best to clean the window with a window scraper before any installation. A window scraper is a glass safe razor blade, usually with a handle that can scrape the glass of any contaminants without scratching the glass. Using the window scraper and installation solution all over the window will clean it of any caked-on dirt that wiping will not remove. You can use the installation solution to also clean the window, as well as any non-ammonia-based cleaners. It is recommended to also clean the surrounding area of the glass, like the frame and seals before installation. Using a no lint or low lint cloth will ensure the glass will be free of any dust. REMOVING THE BACKING LINER Attach one piece of tape to a corner of the film, half of the tape on the film and the other half extending out from the corner. Then use another piece of tape on the other side of the same corner. Both tapes should be placed slightly offset. Hold onto the two tapes and press them together to grab the film's corner tip firmly. Then slowly separate the two pieces of tape; the liner and film should separate. As you gently pull the liner away, spray the exposed adhesive side of the film with the installation solution. This will make the film heavier and easier to manage, and it will also prevent the film from sticking to itself or to anything else. WETTING THE FILM & WINDOW Spray, spray, and spray more! You need to spray a lot to make the film fully wet and to be almost flooded on the film and the window glass surface. Please remember that fully wet window and film is one of the key factors for your successful installation. To handle the film easier when separating the film and the liner, spraying soapy solution liberally on the exposed adhesive side as you pull off the liner will prevent the film from being sticky. This will prevent the adhesive side from sticking to itself, eliminating potential wrinkles and bubbles during or after installation. Once the film piece is on the window, the squeegee should be used with firm pressure to push out the soapy water solution from inside the film, so that the moisture does not continue to interfere with the adhesive after the film has been installed. REMOVING THE FILM WHEN NEEDED Your installed window film can be removed even after years. You need to soften the cured or hardened adhesive of the film to remove the film. A fabric steamer or a heat gun can heat up the film and loosen the adhesive. Using a hair dryer can work, but it will take longer. If there is remaining adhesive residue, it can be easily removed with soapy water and a window scraper. Note that for adhesive films, the removed piece is not reusable. Removing a static cling film is very easy and simple. The static cling film doesn't have the adhesive and can be removed by hand, and you can store the removed film for reuse.

  • Big difference!
Size: 24in X 14ft
I am so happy with this shade film! It allows enough light to pass while stopping a good deal of heat. After all, that's why I purchased it. I use it in my travel trailer. The windows are already tinted and I like light in the trailer. I noticed a difference in the radiant heat almost immediately in my kitchen area. That has made quite a difference. Daytime privacy is great! It's looks great on the windows, inside and out. I made a mistake on the install on one window and there are some creases in it. It doesn't bother me enough to replace it. It's not a window I open the shades on very often. It's a good size for some windows. I didn't measure all the windows so I will be purchasing more in a larger size. I am that happy with it. I looked at several different options before purchasing this. I felt this was the best value for the money. It seems to be a more commercial type product than some of the other films I have used in the past. ... show more

  • Great quality film – effective and easy to apply
Size: 48in X 25ft
This BDF NA35 film was very easy to apply following the instructions – no bubbles, smooth finish, and it looks professional once installed. From the outside, you can still faintly see a person inside during the daytime, but it blocks the clear view we had before, which is exactly what we wanted for privacy. The film reflects more of the surrounding nature, giving the windows a nice mirrored effect. It definitely reduces heat inside, making the room cooler and more comfortable. This version (Natural Black 35 Medium) gives a moderate balance of privacy and light control. Next time I might choose a darker shade for even more privacy, but overall we are very happy with this project. Highly recommend! ... show more

  • Great Product
Size: 36in X 12ft
I purchased this window tint film to eliminate the reflection onto my television from my wall of window shades during the daytime when I want to watch TV. The kit has a great razor; all you'll need is a $1 spray bottle, Dawn dishwashing liquid, tape measure, possibly a right angle, & a little painter's tape. Just follow the directions on the box, and you'll do fine. Unfortunately, the tint I ordered isn't dark enough, and I'm unsure if I want to completely black out my windows. ... show more

  • Heat reduction is legit!
Size: 36in X 50ft
Our mid-west summers get toasty, and our little a/c has been no match trying to keep us cool during the peak, and we can’t afford a full a/c and furnace system swap at the moment. So we have been looking at other ways to keep cool. First, we got some window a/c units, which we will use during the summers in occupied rooms, and we just leave the main house unit off since it runs all day and can never cool the upstairs. Doing this alone dropped our electricity by over half! But thats not enough for me, I wanted to reduce the heat coming in from the windows, as I knew it was significant. Last year we tried black-out film on a few, but it has started falling off, and it looks choppy since you cant see through it while trying to trim around the window during install. So anyhow, that brings us to this year, I found this on Amazon, and the heat and UV reduction is what caught my interest, more so than the tint itself. We watched a few install videos before it arrived so were somewhat familiar with what to do. Once it arrived, I was a little dissapointed because I thought I would be getting the same tint level as the Amazon picture, but this was due to my lack of attention, the other pictures showed what level 35 was. But I decided to go ahead due to the heat blocking advertised, plus we have some beautiful views I did not want to take away from. We picked a less visible window to start with in case mistakes were made, but happily, it was perfect first go! My second attempt was our master bedroom, two large east facing windows that just pump radiant heat into the room for the first half of the day. Now here is what sold me….they are horizontal sliding windows with a left and right side. After i did the one side, there was sunlight shining on the floor from the left side and the right side. And although the sunlight spots looked about the same in intensity, stepping on the carpet from the tinted side was considerably cooler in bare feet than from the untinted side, I even had my girlfriend come do the same and she was shocked! Next we did our biggest offender, the sliding glass door and its side windows. We will be placing another order for the same, and finish up the remaining windows, and I will be very much so watching my electric bill for the next year to compare, but my initial reaponse is that Im very happy with the results. For the install, I found a process that works well: Clean very well obviously, including the gunk at base. Moisten window and razor wipe the entirety, then windex clean twice. Cut film to size (1” extra each side) Remove protective film half way down the tint Spray the window and the stick side of exposed film heavily with soapy water. Stick top of film to window, make sure aligned! Use felt squeegee to get a rough set placement and stick. Squeegee left and right out from the middle, staring and top and working down. Remove the remaining protective film and spray stick side and window with soapy water, finish felt squeegee for the rest of window. After the rough set is done, spray the tinted window with soapy water, then use the hard plastic side of the squeegee and repeat the process from top to bottom (without the re-added soapy wayer, the plastic squeegee grabs). The included razor was perfect for trimming, just be slow and careful. Corners are the most difficult! Inspect the window closely after trimming, and from many different angles, you will often see little ripples….if you catch them at this stage, they easily will squeegee out, just spray the wipe path with a little more soapy water. Then give a last squeegee pass around the edges since thats where most of the water is remaining and bubble/separation is most likely. ... show more

  • Good installation but too light and minimal heat rejection
Size: 48in X 49ft
I don't have a lot of experience installing film but it came out well even on large patio doors using the included tools and instructions. But the level of tint is MUCH lighter than even the lighter % installed on my cars, and the amount of heat rejection is pretty minimal.

Bought the BDF NA 35 window film to reduce heat and glare coming in my wall of windows in the afternoon. I couldn't wait to get it in the mail and get it on the windows.

  • Very Pleased With the End Results
Size: 36in X 24ft
Appreciate the easy to follow instructions, the included cutting blade tool + squeegee, and the product itself. My kitchen windows were different sizes, so I created a cardboard template of each; which made it easy to cut the exact dimensions. The key to putting them up was using plenty of the soap spray; both on the window, and both sides of the film. ... show more
