Glass insulation film origin and development

The use of glass insulation films to improve the safety and energy efficiency of conventional glass can be traced back to 1960. At the time, the original intention of the film was to control the imbalance of heating and cooling caused by the solar load. The early film only had the function of reflecting the solar radiation out of the glass window or absorbing heat to prevent the heat increase on the inner surface of the glass. .

With the continuous development of the manufacturing process, a new generation of body-colored insulating film has been born, and its rich color provides architects with a broad design space. The main colors are: brown, gray, gold, amber, blue, green, etc.

Technology has developed to the present day, the latest technology of glass insulation film produced by magnetron sputtering technology, the color is more important than the metal primary color, but in the film insulation and safety performance has been improved.

In 1970, the US energy crisis led to the development of another aspect of the membrane to reduce the loss of indoor heat energy (ie, "insulation".) The study found that polyester film can not only be used as a transparent medium, but also has the ability to absorb and counter-radiate long-wave infrared. . After trial and error. The material and structure of the membrane have been greatly changed, and the "insulation" of the membrane has been enhanced to produce a "low-radiation film".
