Hai Long's laminated safety glass is a type of strengthened glass with a special structure made of two or more layers of glass, between the layers of glass there is a PVB film, this type of glass can be used heat treatment turning into tempered glass, then glued. together so it can be called another name: laminated tempered glass
In practice, most PVB films with a thickness of 0.38mm are used the most, in addition, there are other PVB thicknesses such as 0.76mm, 0.52mm, 3.04mm, etc.
The characteristic of laminated glass is that when subjected to impact force that leads to glass breakage, PVB film has the effect of holding broken glass pieces from falling out, reducing risks and avoiding causing damage to users. In particular, the film also forms a barrier against outside intrusion (bulletproof, anti-theft...).
In addition, PVB film also has the ability to limit heat effects and harmful UV radiation, minimizing noise.
