BDF NSN70 Window Film Transparent Ultra High Heat Rejection & UV Cut NSN 70 (Very Light) - 48in X 24ft

I tested it with a transmission meter I got off Amazon: Visibility: 75% UV blocking: 100% IRR blocking: 50% I hired a Taskrabbit with a lot of experience in installing building and vehicle window films. He said this is one of the lower quality films he's worked with. It creases easily, unlike the higher quality ones. I bought a different one from China and he said that one was a lot better (it was also half the price), and that one has the same visibility and UV but blocks 83% IRR which is even better.

I was tasked with installing this in a great room with huge 8' x 4' triangle shaped windows with the top of the window about 22'. It was a bit tricky pulling the backing off and keeping it straight since the sheet was huge and being up on a 15' ladder, I didn't have any help from below. I have used other films, but never in a situation this difficult. The film is very forgiving. Most tints I have used previously used would have had noticeable crease marks if it got folded over like this did. It folded over a couple times and I thought sure I would have a crease or two, but they all came out perfect! In total I did about 100 sq ft of windows just in the one room, all look great. As for heat rejection, it has lowered the room temp about 7-9 degrees on a sunny afternoon. I am very pleased with this film. I did have issues with the shipping, as the box was beat up and creased in the middle, along with the film inside. Product was returned and replaced, but the second box was also bent, but luckily the film was OK this time. They really need to work on their packaging, as a 4' long box seems to get bent/folded very easily during shipping. Other films I have used were shipped in a very strong tube, perhaps they should try using a tube vs box.

Pretty easy to install if you follow the directions exactly. There's a suggested video which is quite explanatory. Comes with the necessary tools. Use a large table to lay it out. Really press hard using the supplied squeegee to work out the liquid and bubbles. Measure the windows you want to do beforehand. I "guestimated" and came up short and had to reorder a second piece. After measuring your windows exactly, add 2 inches horizontally and vertically since you need a bigger piece during install and then cut away the overlap. Lay out the window squares on a simulation of the various sizes available to reduce the amount of waste. I -was- able to use the straight "factory edge" on a couple of the windows without cutting back. The main reason I installed it was to eliminate/reduce the UV bleaching my indoor carpets and furniture. After installation, the view through the windows is virtually unchanged.

Excellent product, description is accurate. When applied properly, it is exceptional

My westward facing windows heat up my house tremendously. I got this just to try and see how it would do. I have an infrared heat gun thing and after doing one part of a window there was a 5° heat decrease between the window with the film and the bare part of the window. That doesn’t sound like much, but for an essentially clear film it made a huge difference in the temperature of our livingroom. I’m going to be adding this stuff to all of our windows. Hoping to keep the electricity bills under control this summer. This should help!
