Multilayer fully sputtering window film represents top-tier technology and quality in the field of window films. As one of the most advanced pure metallized films, it uses sputtering technology to apply ultra-fine layers of metal onto PET film, delivering unmatched heat insulation and visual performance. By combining over 12 layers of premium metallic microparticles such as nickel, silver, titanium, gold, and platinum, Dupotop’s window film precisely reflects and blocks solar radiation, making it an outstanding choice for buildings, automotive, and marine applications.
