## Overview

The BDF NSN70 Window Film is a premium transparent vinyl film engineered with a nichrome-silver alloy sputtered layer that rejects 45% of total solar energy and blocks 99% of UV rays. Designed for ultra-light visibility, it reduces heat gain while allowing abundant natural light, protects interiors from fading, and features a scratch-resistant surface with durable adhesive for long-term use. Additionally, it reflects thermal energy back indoors during winter, enhancing year-round comfort.

## Description

Buy Decorative Film's sputtered films are reflective films effective at rejecting more heat than traditional dyed films. We offer sputtered films comprised of a wide array of metals to match whatever color or shade is required for a project. Because there is no dye in our sputtered films, they will not fade throughout the entirety of their lifetimes. Additionally, our layering technology limits oxidation to ensure that our films will last far longer than expected. The metal in the NSN series is comprised of an alloy of nichrome and silver. By combining the strengths of these metals, this alloy provides the film excellent reflectivity and outstanding overall performance. - Light Reflectivity - Excellent Heat Rejection - 99% UV Rejection

Review: I bought this film to apply under the Skylight that I just replaced. My old Skylight was cracked, and since it's 50 years old, very few new Skylight will fit. I bought the only one I could find, and I was not so satisfying with it. It was medium grey, color and not as dark as my old Skylight. My house is already hot as hell with the old Skylight, so imagine that with a lighter color Skylight. As the sun shined through the Skylight, it left a large rectangle moving through my carpet, then my staircase, then on to the wall. Looking at it was like looking at a 150-200 watts incandescent light bulb directly with the new Skylight, so I had to use my hand to cover on side of my face every time I walked by, to keep my eyes protected. it's that bad. And here is where the tint film came in. I applied 4 layers of this film, BDF NSN70, directly under the Skylight because it was for interior use. I cut each layer in 3" stripes and overlapped them so that they could conform to the curved surface of the Skylight better. It was still imperfect, but looked more decent than apply the whole film on the curved surface. It still didn't look good. Then I went to Home Depot and bought a 2x4 defusing panel that you normally installed on the ceiling below the fluorescent lights. This was done to defuse light better, and also make the Skylight look good since the flaws wouldn't show up through this panel. I then installed the Skylight with the pannel sandwiched in between the Skylight and the roof, rough side of the panel down. The result: ABSOLUTELY AMAZING !!! I just couldn't believe it! This cut the heat absorbed through the Skylight by 95%. You read it right, by 95%. I stood directly under the Skylight with the sun shined directly over my head, and I can feel the heat on my skin: It was only VERY SLIGHTLY WARMER THAN MY OWN BODY TEMPERATURE and the outside temperature was 85 degree. The sun shine had been cut down so much thru out the day, and the light color was actually WHITE all day long, not YELLOW as it should be any more. It was like looking at a 40 watts fluorescent white light bulb from a distant. The light was slightly darker before noon, and from noon on, it was at full capacity, which was gentle and very easy on eyes. For me, this was perfect. If I wanted it brighter, 3 layers would do that, with a little temperature gain, of course. So, the template now was the temperature of the house coming from doors and windows, but no longer from the Skylight. The defusing effect of the panel also dispersed the light out such that it created a more even light through the area, and I no longer saw the sharp rectangle sun glow on the wall anymore, that was the end of it. Needless to say, the result was sort of unexpected because from my calculations, I never knew that it would turn out like that, but hey, who is complaining? An important thing I learned from this exercise is this: If you want to use a film for heat blocking, try an MIRROR EXTERIOR FILM first. I used the BDF EXS35 for my windows and doors that I wanted to see more out of those, and BDF EXS15 for my master bedroom to cut the heat to a minimum level so that I can sleep in it in the afternoon. This will cut the heat by 60% and 80% respectively. I plan to apply the BDF NSN70 to the interior of the same glasses to cut the heat down another 15% and 8% respectively, making the heat rejection totals to 75% and 88% respectively. This will bring the temperature down further, but affects the views very little. The BDF NSN60 will not be that much more gain to consider. Note that I mentioned MIRROR FILM here, preferably the SPUTTERED type for EXTERIOR use, and NOT the regular black or dark gray films. Black color attracted heat, so, initially the black film blocks heat by blocking sun light, but given enough time and the right sun angle, the sun light turns into heat, and heat will start to radiate into the room because the film only blocks light, not heat, so the later part of the day (4-6pm), it will be the hottest. I used to come home from work almost every day and it was ok, but now I stay home all day everyday, so I realized how much discomfort it was with the black film. And from the experience I gained from doing the Skylight, I no longer again tint my glasses with black or dark grey films. Hope my experiments here will be of some helps for those who needed it.
Review: This product did NOT reduce heat in my room at all. I measured the temperature of the area near the window and in the room of 2 rooms right next to each other, with the same exact angle to the sun. One room had no widow film adhered to the window and one room had the window film adhered to the window. Both rooms had the exact same temperature near the window and in the room. What a hoax!!! I could not measure UV light, but I bet this film did not help that either!! I was hoping with the window film and some shades, the heat in the rooms in direct sunlight would be reduced. The film does not help at all. I will tear off this window film and continue my search for heat reduction in the room.

I bought this product with the specific intention of blocking out heat from the sun. After installing 3 windows, I decided to take a break. When I came back to finish window 4, I noticed that the last 3 hours of my life were an absolute waste of time. I honestly think this window film magnified the sun rays and made the room hotter. TOTAL WASTE OF TIME and money. Get a reputation ceramic window film.
