The multi-layer magnetron sputtering double silver series has the characteristics of high clarity and high heat insulation. The thickness of 3 mil is safer. The magnetron sputtering technology window film can effectively reflect most of the heat of sunlight, so that the temperature of the car interior is effectively controlled. At the same time, its visible light transmittance is high, and the road conditions and surrounding environment ahead can be clearly seen during driving, ensuring driving safety. The perfect amber luster can match various vehicles.
