Safety glass is made by laminating two pieces of glass together with a sheet of plastic in the middle. You heat up this little sandwich and press everything together, and the plastic melts and sticks to the glass. Once everything cools down, it looks just like a normal piece of glass, but if you smash it, the plastic holds everything together.
How to cut glass safely?
The preparation on how to cut safety glass must be done outside or on a hardwood surface. Do not cut glass in a carpeted room, as glass particles may get stuck in a pile. Always, do make sure you have full-duty gloves on and safety goggles on. Prepare a clean, smooth, hard glass cutting surface like a solid workbench or a thick sheet of plywood.

Is shatterproof glass bulletproof?
Unbreakable window glass (also known as shatterproof glass) is proclaimed to be the original bulletproof glass. It gets its reputation as “unbreakable” due to the unique way it crumbles upon impact, collapsing into small, harmless pebbles instead of sharp, cutting pieces.
Can unbreakable glass be broken?
Laminated Unbreakable Glass When laminated glass is struck hard enough, the outer glass layers will crack and, in some instances, shatter, but the plastic polycarbonate film that is affixed in-between the panes will remain intact.

How does tempering glass work?
The tempering process increases the strength of the glass to five to 10 times that of untempered glass. Tempered safety glass breaks differently than regular clear glass. When tempered safety glass is struck it does not break into sharp jagged pieces of shrapnel-like glass as normal window panes or mirrors do.

Tempered safety glass is a single piece of glass that gets tempered using a process that heats, then quickly cools, the glass to harden it. The tempering process increases the strength of the glass to five to 10 times that of untempered glass.
How to strengthen glass?
Another way to strengthen glass is to use more than one lite of glass in the application. Laminated glass consists of two or more lites of glass joined by a layer of plastic. Heat-strengthened glass is made by heating annealed glass uniformly, then cooling it at a slow rate.
What makes glass stronger?
Making Glass Stronger. Two types of safety glass are heat-strengthened and tempered. Heat-strengthened glass is cooled at a rate faster than regular annealed glass. Tempered glass, in turn, is cooled at a faster rate than heat-strengthened glass. Another way to strengthen glass is to use more than one lite of glass in the application.
What Is Wire Glass?
Wire glass is made by feeding a welded wire net of a particular design into the molten glass just before it enters the rollers. The wire does not add to the strength of the glass but it does hold the lite (a cut piece of glass) in the window sash if it shatters. Wire glass is used in fire-rated windows and doors because it meets most fire codes. For these applications, all the wires must be embedded in the glass. However, even though it meets fire codes, wired glass is not strengthened glass. In fact, it has only one half the strength of annealed glass of the same thickness. In addition, wired glass cannot be tempered.
What Is Laminated Glass?
Laminated glass, sometimes called “lami,” is made by placing a layer of polyvinyl butyral (PVB) between two or more glass lites. The PVB can be clear or tinted and commonly varies in thickness from .015" to .090", but it can be as thick as .120" for special applications. The entire unit is then fused under heat and pressure in a special oven called an autoclave. The laminating process can be performed on clear, tinted, reflective, heat-strengthened or tempered glass.
How is tempered glass made?
Tempered glass, (also known as toughened glass) is made by heating annealed glass uniformly. The annealed glass is then cooled rapidly by blowing air uniformly onto both surfaces at the same time. This is known as air quenching. Rapid cooling increases the compression forces on the surface and the tension forces inside the glass.
What is a PVB windshield?
A vehicle windshield is made of a layer of laminate sandwiched between two layers of glass.
Why is tempered glass considered a safety glass?
Tempering increases the ability of glass to survive the impact of objects that may strike the building. When tempered glass does break, it shatters into small cubes, reducing the likelihood of serious injury on impact. Therefore, it qualifies as a safety glazing material.
