Laminated Glass(KS L 2004)
It is a glass created by inserting a transparent and highly adhesive polyvinyl butyral film between two sheets of plate glass, after completely removing air from the plate glass and then increasing the temperature and pressure to adhere them closely.
Its low breakage rate prevents glass fragments from scattering when it gets broken, so it is a safe glass. In addition, it protects against theft and blocks about 99% of UV rays.
Various colors can be implemented by different colors of the film used. (Transparent, green, bronze, blue)
Sound Insulation Glass
