Glass doors, glass windows and glass curtain walls; Bulletproof and explosion-proof places; Vehicles and ships; Places with thermal shock such as shower rooms, steam rooms, baths, and saunas, etc.; Large area of glass exterior wall, stations and banks. So, what are the advantages of such building energy-saving safety film?
1.0 Fire protection. The safety film can resist high temperature so that it can prevent the damage caused by the hot brittle collapse of the glass under high temperature conditions, and delay the softening and collapse time of the glass under high temperature conditions.
2.0 Environmental protection. The building's safety film has a UV shielding rate of 99% or more, to protect the skin from direct sunlight.
3.0 Anti-theft. The hardness of the building safety film is 500% of that of common glass. This film also has a high tensile strength of 30,000 Psi. In addition, the 160% high stretch makes it difficult for gangsters or violent elements to break through and delay their intrusion time.
