What Is Laminated Glass Made Of

Laminated glass is a type of safety glass that is made of two or more panes of annealed glass joined together by a layer of plastic or polyvinyl butyral pvb.

What is laminated glass made of.

The pvb sheet bonds with both the layers of the glass and keep it intact even upon impact. Ordinary annealed glass breaks easily. Laminated glass is a type of safety glass that holds together when shattered in the event of breaking it is held in place by an interlayer typically of polyvinyl butyral pvb ethylene vinyl acetate eva or thermoplastic polyurethane tpu between its two or more layers of glass. What is laminated glass.

Laminated glass and tempered glass. The mechanical bond occurs through the adhesiveness of the pvb. Laminated glass is made by sandwiching a layer of polyvinyl butyl pvb between two or more panes of glass. The glass and the pvb are sealed by a series of pressure rollers and then heated.

But laminated glass is different. Safety glass is manufactured in several ways. Both tempered and laminated glass are considered safety glazing as required by building codes but only laminated glass can prevent a hole from forming in a fractured panel thus explaining its extensive use in building envelopes. This combination of pressure and heat chemically and mechanically bonds the pvb to the glass.

The plastic layer of the film does give the glass a stretchable quality but don t imagine the glass stretching like a rubber band. Laminated glass can be made stronger by adding layers making the end product thicker. Remember car windshields are made with laminated glass and are subjected to rain snow high temperatures and sub zero ones as well. Laminated glass is made by sandwiching a layer of polyvinyl butyral pvb between two pieces of glass.

The laminated glass has just enough give and stick in it to hold the glass in place if it were to break. The bond between pvb sheet and glass is a chemical bond and thus it does not delaminate easily. Modern shower doors can also be made of laminated glass or laminated tempered glass. The result is a panel that remains intact even if the glass gets broken.

Tempered glass while stronger shatters under a greater impact. Glass formed by filling a mold with molten glass. The glass sheet for making laminated glass can be ordinary glass float glass tempered glass colored glass heat absorbing glass. The interlayer keeps the layers of glass bonded even when broken and its high strength prevents the glass.

If laminated glass is broken the vinyl interlayer remains in the frame with glass fragments adhering to the interlayer. This post will focus on two of the most common types of safety glass. Laminated glass can be made from annealed glass from tempered glass or from combinations of the two.
