BDF's Premium Silver/Gray window film is a highly reflective window film that enhances daytime privacy. If the film is installed on a window, the film's silver color on the outside gives the window a mirror-like, reflective appearance on the silver side when the sun makes the outside considerably brighter, while allowing the people inside to see the outside scenery through the window during daytime. The neutrality of the gray color on the inside can promote a calm, serene atmosphere in your home. KEEP IT COOL & REDUCE ENERGY COSTS The silver-out / gray-in tint is rated to transmit about 9% of visible light and helps reduce glare. Not only does the RPRGY window film provide great daytime privacy, but its metalized dual reflective nature also gives it excellent heat rejecting properties that keeps your interior nice and cool, blocking about 79% of the total solar energy coming in from the sun. This helps maintain your room at a cool, moderate temperature, resulting in lower cooling costs. Silver Outside, Gray Inside Cuts 79% of Total Solar Energy Reduces Your Cooling Energy Cost EXCELLENT PRIVACY DURING DAYTIME The effect of any daytime privacy window film will greatly depend on the brightness on each side: the side that has more light can be seen from the other side through the film, whereas the darker side is concealed by the film. This is why the privacy effect works so well during the day and almost not at all at night, since the sun usually makes the exterior of your building much, much brighter than the interior. At night, you will most likely have your room well-lit while the outside will be much darker, making it easy for people to see in and hard for you to see out. However, coupled with the use of curtains or blinds for nighttime, the dark window film is perfect for windows that face directly into the sun and are exposed to extreme sunlight! Excellent Daytime Privacy Mirror-like Reflection Outside during Daytime Curtains or Blinds are Needed for Nighttime Privacy PROTECT FROM UV RAYS Good for homes and office buildings that are directly exposed to the sun which is the source of the UV rays, the RPRGY 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 RPRGY film rejects about 99% of the UV rays, helping to reduce fading on your precious furniture, pictures, or other UV-sensitive belongings. 99% UV Rejection Rate Protects Your Family from UV Protects Furniture and Wall Pictures OUR HEAT CONTROL FILM COLLECTIONS & SPECIFICATIONS: all data values are for comparison purposes only RPRGY (Silver Outside, Gray Inside) PRGY (Gray Outside, Silver Inside) S05 (Very Dark Silver) NA05 (Very Dark Black) Customer Reviews 3.9 out of 5 stars 45 3.9 out of 5 stars 9 4.4 out of 5 stars 754 4.5 out of 5 stars 4,026 VLT (Visible Light Transmittance) 9 % 9 % 12 % 5 % Shade Very Dark Very Dark Very Dark Very Dark UV Rejection 99 % 99 % 99 % 99 % Total Solar Energy Rejection 79 % 75 % 80 % 55 % Shading Coefficient 0.24 0.28 0.23 0.52 Dual-Pane Friendly Yes Application Inside Window Inside Window Inside Window Inside Window To Start: Cleaning the Window & Preparation Install the window film on a cool day and not in direct sunlight. An adjacent work surface next to the window is recommended. It will be much easier to install film on smaller windows, so we suggest starting with the smallest windows first. 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. The installation solution can be made by adding 8-10 drops of liquid soap for every 16 oz. of water. Separating the Backing Liner from the Film Window films have 2 parts: the actual film and the backing liner. Find a corner of the film to separate the liner and film. The liner will always be clear and thinner than the film. The best way to separate the film and liner is to use two pieces of tape. 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. When the liner is all pulled away, the film's exposed adhesive side should be fully wet. Handling the Sticky Window Film 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. Also, the soapy solution should be sprayed on top of the film surface prior to the squeegee use. This will help your squeegee glide across the film. Can I remove this film later? 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.
