Broken Laminated Tempered Glass

Laminated glass laminated glass is made of two pieces of glass held together by a plastic film or resin.

Broken laminated tempered glass. Laminated glass aids in the screening of uv radiation. One of the biggest benefits of laminated glass is that if it does break the broken glass will stick to the plastic rather than falling to the floor. Laminated glass is beneficial for soundproofing. When laminated glass is broken it is held in place by an interlayer typically of polyvinyl butyral pvb between its two or more layers of glass which crumble into small pieces.

It is made of two or more plies of glass with a vinyl interlayer between sandwiched if you will as in a car s windshield. When tempered glass is broken as shown above it shatters into thousands of tiny pebbles practically eliminating the danger of human injury caused by sharp edges and flying shards of glass. This video is about the difference between tempered laminated and standard glass. Laminated safety glass keeps those pieces of glass safely in place.

When broken the pieces are held together by the plastic layer reducing risk of injury from shards of glass. It is known to be 4 5 times stronger than regular glass and can withstand temperatures up to 295 degrees celsius. Laminated glass is basically a glass sandwich. The former is called tempered or toughened glass and is used in shower doors refrigerator trays architectural glass doors and tables bullet resistant glass and smartphone screen protectors a rather recent development.

Although dull these can still be a hassle. Tempered glass when broken forms many small bits rather than shards. The surface compression of heat strengthened glass makes it approximately twice as strong as annealed glass. Laminated glass is composed layers of glass and plastic held together by an interlayer.

Tempered glass is very safe but if somehow broken still results in loose pieces of broken glass. The plastic portion of laminated glass may be clear or tinted. The research presented herein aimed to simulate the structural behavior of laminated glass with all the glass layers broken by means of the discrete element modeling. This paper focuses on laminated glass composed of two layers made of tempered glass and an interlayer made of either a totally compliant or a relatively stiff material.
