Laminated glass is a sandwich made of one interlayer of plastic Poly Vinyl Butyral between two or more glass layers. Generally PVB thickness ranges from 0.38, 0.76, 1.14 & 1.52 mm. PVB keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. The plastic interlayer also provides protection from ultraviolet rays and attenuates vibration, which gives laminated glass good acoustical characteristics. As laminated glass has good energy absorption characteristics, it is also a critical component of protective glazing, such as blast and bullet-resistant glazing assemblies. Laminated glass produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. Skylight glazing and automobile windshields typically use laminated glass. In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtain walls and windows.
Two layers of toughened glass bonded by a lamination to create a shatter proof material that can be laid horizontally either at the floor level or above the head. The shatter proof characteristics provide adequate safety to human inhabitants. Glass & Glazing provides a UV stabilized resin lamination which is more environmentally sustainable and also provides a sound reduction of 35 decibels.
