Wigan, United Kingdom (PressExposure) May 08, 2009 -- Laminated glass is safety glass that holds together when it is smashed or shattered. On impact, the glass is held in place by an interlayer between its two or more layers of glass. When any damage occurs, the interlayer keeps the layers of glass bonded together. Its strength prevents the glass from breaking into harmful shards. Instead there is the spider web effect across the glass surface.
Laminated glass is used in case of possible human effect or where glass could fall if shattered. Laminated glass is said to be of two types â plastic laminated glass and resin laminated glass. Firming together two or more layers of glass with a plastic interlayer called Polyvinyl Butyral or PVB produces plastic laminated glass. The plastic is sandwiched by the glass layers and then passed through rollers to expel any air. This forms the initial bond that is then heated to high temperatures in an oil bath. Resin laminated glass is made by pouring liquid resin in between two sheets of glass then held together till the resin cures. The French chemist Edouard Benedictus invented laminated glass in 1903. Its first widespread use was in eyepieces of gas masks during the First World War.
Laminated glass is used where issues of human safety arise. Itâs an excellent barrier against forced entry and cannot be cut from one side only. Thus glasscutters are rendered useless. Laminated glass is also used in homes and offices where there is prolonged exposure to sunlight. Clear glass allows most of the UV rays to pass through. Laminated glass instead is able to block out 95 % of the UV radiation while allowing nearly all visible light through. Most automobiles have laminated glass windows. Itâs extremely useful in areas requiring protection against high speed or cyclonic winds and storms â in the exterior of shops/businesses, curtain walls and windows. It also prevents harmful effects of debris from storms. Laminated glass is an effective way to diminish unwanted external noise and disturbances. It reduces noise due to the damping effect. Thus its great use in areas near airports, industrial zones, high traffic etc.
