Laminated glass is a type of safety glass made by sandwiching a layer of plastic, usually polyvinyl butyral (PVB), between two or more layers of glass. This construction helps to hold the glass together even when it is shattered, reducing the risk of injury from sharp shards. It is commonly used in automobile windshields, skylights, and glass doors. In addition to safety, laminated glass also provides sound insulation and UV protection. The plastic interlayer can block harmful ultraviolet rays, helping to protect interiors from fading. This makes laminated glass a popular choice for both residential and commercial buildings.
