I want to ask, if the home is already hollow glass, that still need to foil it?
In the selection of insulating glass raw materials, enterprises one-sided pursuit of profit maximization, resulting in unstable quality of raw materials. Such as sealant is one of the main raw materials of insulating glass, it directly affects the energy-saving effect and service life of insulating glass, but the low price inferior sealant material is still in mass production.
The insulating glass production enterprises are numerous, and the enterprise scale is relatively small. The quality of products is unstable. Products are good and bad, the phenomenon is more serious, even worse, inferior insulating glass is still flooding the market.
Insulating glass insulation effect is very good, but insulation, UV effect is not good. If a glass film is attached to the inner glass, the heat insulation effect is more marked, and the harmful ultraviolet ray can be effectively separated from the 99%, and the glass can be prevented from splashing after breaking.
