Nanometer blue tungsten oxide may be applied for preparing thermal insulation film so that such thin film will have the properties of high transparency (visible light transmittance higher than 70%), high heat insulation effect, one-way see-through, privacy, anti-glare, and anti-UV (UV blocking rate is up to 99%). Also, the heat-insulating film is explosion-proof and environmentally friendly. With such a thermal-insulation film, there is no need to pull the curtains. And you can enjoy the beautiful scenery outside the window more than ever. More importantly, the film can not only get the effect of heat insulation, but also keep the room warm.
Some friends may be curious - how can such a thin film be kept warm? In fact, this is because this layer of heat insulation film can reflect the indoor heat source (far infrared rays) back into the room. So the effect of heat insulation is. It must be said that the ding of blocking ultraviolet rays of blue tungsten oxide is better than other common heat insulation film. As is known, excessive ultraviolet radiation is not good for the human body and furniture. This film can protect the skin from damage. Also, home furniture, flooring and fabrics are not easy to fade.
