Unlike conventional, dyed films, BDF's sputtered High Heat Rejection & UV Cut NSH70 window film is more effective in rejecting heat from the sun. With a nearly transparent shade that is slightly reflective, the NSH70 boasts excellent reliability in that it will not fade throughout the entirety of its lifetime as it does not contain any dye. Because it is almost completely transparent, you do not have to worry about whether or not your window will still have a view. The very light film lets in plenty of visible light and contains a nichrome and silver alloy that makes your window slightly more reflective. If privacy is not of big concern but solar control is, the NSH70 would make a great choice.
