Tungsten trioxide nanopowder may be used to prepare a transparent heat-insulating film and thus be applied to the architectural glass to obtain an environmentally-friendly transparent heat insulation glass. This new type of thermal insulating glass not only has a heat-insulating effect, but has a heat preservation effect. In addition, it can shield most of the ultraviolet rays, thereby reducing the damages of indoor objects due to the exposure to UV rays.

As we all know, the ultraviolet radiation in the sun is the main culprit in the fading and aging of carpets, furniture, art paintings, curtains and chemical fiber fabrics. It is also the culprit leading to skin diseases and even skin cancer. Therefore, it is necessary to block UV at home. In this regard, experts say that the tungsten trioxide smart film allows visible light to enter, while shielding up to 99% of harmful UV rays, which is deeply loved by the construction industry. In addition, although the heat insulation glass film is transparent, it is also a private ding - one-way perspective to prevent outdoor peeks.
