WO3 nanopowder may be used to prepare a heat-insulating energy-saving film, which is a new type of smart film with the advantages of environmental protection and energy conservation. This is a thin and transparent heat insulation film with only a few microns thick. It can be applied to the glass windows and doors of the living room to solve the annoying problems, and therefore you can have a spacious and bright space with high thermal insulation performance.

The transparent film of tungsten trioxide nano particles can shield more than 99% of harmful ultraviolet radiation to protect fabrics, furniture, paint and many other indoor items. Such energy efficient film can also shield more than 75% of the solar heat, that is, prevent the infrared rays from passing through the glass. And it will not affect the indoor light. Besides, the energy-saving film also has excellent privacy or one-way perspective, which meets the requirements of enjoying the outside scenery and protecting privacy. This is the reason why more and more architects and designers are in favor of using tungsten oxide heat insulation films on the buildings they design.
