Safety Glazing


Safety Glazing is the name given to glazing products which meet a certain building code. They are designed in different ways for different functions. Tempered safety glass is the most popular and cost effective type of safety glazing. It is a heat strengthed glass. It is up to 5 times stronger than annealed glass. When it does break, it shatters, like the side window of a car, into thousands of small pieces. The pieces prevent serious injuries from occurring.

Laminated glass is two lites of glass with a plastic layer in between. When one of the outer lites is broken, the plastic layer prevents large jagged pieces of glass from falling and causing a major injury. It also slows down someone who might be trying to enter a building. The plastic layer prevents an intruder from easily getting through the glass.

Acrylic and plastics are the third type of safety glazing. The less expensive acrylics will yellow and scratch over time. But they are much harder to break and when they do, they will not cause serious injury. Lexan, a product manufactured by GE. Lexan has the same visual clarity of glass, but the structural integrity of heavy-duty plastics. It is scratch resistant and nearly unbreakable.
Please look below to see if your window requires safety glazing. ( All doors require some type of safety glazing.)
