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". PRIVACY WITH THE VIEW During the day, no one will be able to see in, while you will be able to see out perfectly. Our Dark Black Film The dark window film will reduce the amount of light coming in. Beat the Heat Heat blocking technology in the film will help reduce the amount of heat passing through the window. Beautiful black film Black film will completely transform the look of your windows and outside appearance with subtlety. Same film the PROs use We wanted to bring the same films that professional window film installers use to the public. BDF NA20 and the Natural series window films are the same ones that are used by professionals. Many businesses and home owners have had this film installed by pros, and now you can have beautiful windows at a fraction of the cost. Enjoy a nice shade with BDF's Natural 20 window film. This film has a dark enough shade to provide daytime privacy, but allows relatively more light through than darker films. It prevents unwanted eyes outside from seeing what's happening inside while retaining view from inside during the day. BDF NA20 black finish provides excellent daytime privacy, making it hard for unwanted eyes to see through. The dark black tint of the NA20 helps reduce glare. The "20" in its name refers to the fact that it is rated to transmit about 25% of visible light. Not suitable for dual pane windows. The NA20's black-tone nature gives it an excellent heat-rejecting rate of up to 50% that keeps the interior of your home or office building nice and cool. BDF Natural series window films help reduce cooling costs, especially during the summer through the effective blocking of harmful solar rays.

The video guide shows an overview of the installation steps. Reviewing and following the proper steps allows a clean and smooth application process, so that you can then enjoy the benefits of the newly installed window film - whether it is the energy efficiency made possible by a sun control film, the added protection and peace of mind of a security film, or the stylish aesthetics of a decorative film.

Reviewing and following the proper steps allows a clean and smooth application process, so that you can then enjoy the benefits of the newly installed window film - whether it is the energy efficiency made possible by a sun control film, the added protection and peace of mind of a security film, or the stylish aesthetics of a decorative film. Using an excessive amount of water solution (16 oz. water + 8 drops liquid soap such as baby shampoo) will make handling the film easier. Spraying water solution on the adhesive as you pull off the liner will prevent the film from being too sticky. This will also reduce or eliminate the potential for wrinkles and bubbles during installation. Once the film is properly placed on the window, the soapy water should be pushed out using the squeegee with appropriate pressure applied. Attached to the film is a clear layer called the backing liner. This layer covers the adhesive or cling side of the actual film layer; the liner needs to be removed when you install the film. The best way is to use two pieces of tape on a corner (one on each side, facing each other). One piece would grab onto the film, and the other onto the liner. Press the tapes together, and then slowly separate the two pieces to pull the two layers away from each other. Static reaction happens when the backing liner is taken apart from the film. It may cause the film to stick to itself, which makes that film useless. To prevent this, spray the soapy water solution as you carefully pull off the backing liner. The window surface should also be sprayed with plenty of the soapy water. This can be used to clean the window before applying the film, and allows you to move the film around on the window without it getting stuck on the surface. A daytime privacy film can prevent onlookers outside from seeing in while retaining view from inside during the day. The effect will depend on the brightness on each side: the space that has more light can be seen through the film from the other side, whereas the film conceals the space that is darker. This is why the privacy effect works well during the day, since the sun usually makes the exterior of your building brighter than the interior. Curtains or blinds will be needed for nighttime. Why does the film not stick to the window? / Why did the film fall off from the window a few hours later? There is a clear "backing liner" layer attached to the actual "film" layer. The backing liner covers the adhesive on the film so that the film does not prematurely stick. When you install the film, the backing liner needs to be peeled off from it. Can people see in at night? / Why is the interior visible from outside during nighttime? If lights are on inside, the interior will be visible at night because it is brighter. Curtains or blinds can be closed at nighttime to block view. (During daytime, you can see out while having privacy from outside due to the sunlight outside.) Why does the window feel warmer after the film has been installed? This is an expected result. The window with the film installed feels warmer because the film stops some of the heat. If the film is not there, the heat felt on the window would instead enter the room. Why did bubbles (or spots where film is not adhering properly) form after the film was installed? This is due to the moisture left inside. The film may appear fine when installed, but afterwards, the water can interfere with the adhesive and cause bubbles to form. Apply firm pressure with the squeegee and push out the water to prevent bubbles. Can this film be used on dual pane windows? This film is not recommended for dual pane windows due to the higher heat absorption rate. This can build up heat between the panes, which would stress the window. (Heat absorption is different from heat blocking rate.)

  • Easy to install and looks great.
Size: 36in X 50ft
I’m really impressed with this window tint for my home! Not only does it effectively reduce glare and block harmful UV rays, but the installation process was incredibly easy. The tint went on smoothly with no bubbles or wrinkles, even though I’m not a professional. It fits perfectly and looks sleek without making the rooms feel too dark. Plus, it helps keep my home cooler and adds privacy without sacrificing natural light. If you want a simple, hassle-free way to upgrade your windows, this tint is definitely worth it! ... show more

  • Good Quality Film, but Installation Takes Experience
Size: 48in X 50ft
Overall, this window film is good quality. The film is thick and durable, and it arrived in perfect condition with no scratches, creases, or damage. Once installed, it looks great and provides good daytime privacy and sun control. However, if you don’t have experience installing window film, it can be challenging to apply due to its thickness and stiffness. Beginners may struggle without proper tools or practice. The price is a bit on the higher side, which is why I’m giving it 4 stars instead of 5. Otherwise, it’s a solid product that does exactly what it’s supposed to do. ... show more

  • Great for cabinet windows, terrible utility knife
Size: 12in X 50ft
Wife and I got tired of looking at all the cables and do-dads we had hiding in the living room cabinets, so we purchased this (NA20). I pre-cut the sections to make things easier, and we were able to finish 8 windows in about 45 minutes. This was PERFECT, and looks great in the living room. You can still faintly see light through it (red is the most apparent), but it blocks things enough to where it’s not distracting. Super easy to cut, but do NOT use the knife they include or you’ll be tearing the film; we used a Husky utility knife from the HD we already had lying around and it took care of it with no issue. It also sticks really well, so work quickly; it can be re-positioned, but make sure you re-spray the area when re-applying. Last piece of advice is to be really careful when using tape to pull the film off, or when separating the layers in general: any creases or accidental bends will be stuck on the film after you place it. Only time will tell if those folds will diminish as things dry out. ... show more

  • It’s a window, but darker
Size: 48in X 12ft
I got the BDF NA20 for a large window in my house that faces the street and it’s the perfect tint! It’s crystal clear looking through but still dark enough to provide enough privacy and heat reduction. I read reviews about it creasing so I handled it delicately and painters tape to hold it up while I positioned it, thoroughly soaked it with water from a spray bottle on both the window and film, and pulled off the backing. Make sure the window and the frame are perfectly clean because once it’s on and drying it sticks hard, and trying to peel it back will damage it, so try to make sure there are no hairs, dust, or particles, as it’s definitely static cling and will grab those things. Followed the directions and it’ll come out perfect! I bought some prior to this that had horrible, murky visibility, but this stuff just looks like a window with added privacy and sun filtering. It works exactly as it should and for the price it was extremely worth it! ... show more

  • Stylish Privacy with a Cozy Ambiance
Size: 48in X 12ft
This pack of window privacy film is a fantastic solution for enhancing privacy while adding a touch of style to your space. Easy to apply with just water and a squeegee, it adheres securely without adhesive, making it both user-friendly and reusable. Once installed, it effectively blocks prying eyes and softens incoming light, creating a dimmer, more relaxed ambiance. The frosted or patterned finish not only adds a decorative touch but also reduces glare, making your space feel cozier and more inviting. It isn't the best for our living room due to the filtered light, but it's perfect for bathrooms, bedrooms, or any area where you want privacy and a softer glow, this privacy film is a practical and elegant way to upgrade your windows ... show more
