How Much Does Tempered Glass Cost?

Written by: Staff

Tempered glass, often referred to as toughened glass, is a type of safety glass that is treated with heat or chemicals to increase its strength compared to normal glass.  If tempered glass is broken, it will not break into sharp shards of glass; instead, tempered glass shatters into smaller granules.  These chunks of glass are less likely to cause injury when compared to the traditional glass that breaks into larger shards.

Tempered glass is commonly used in automobiles and cellphone screens, but it can also be used inside a home or commercial buildings.   The price of tempered glass will depend on the company manufacturing it, the size and if custom cuts are required.

Additional costs will differ depending on the type of tempered glass you will buy.  Since tempered glass can be bought to be installed in windows and other fixtures, the additional cost would involve paying for the installation of the glass.  Installation costs will greatly depend on the size of the job and other factors.

Customized cuts or colors can add to the price estimates mentioned above.  Some companies may be able to remove the jagged edges for an additional fee as well.

Tips to know

Tempered glass, according to Floyd Glass, is known to be the hardest types of glasses on the market.  As noted above, it will break into smaller square pieces if it were to be smashed or someone came into contact with it.  To create this glass, it will use a mix of chemicals and heat.  The only downfall, when compared to other types of glass, are the edges, which are the weak point.

Some state laws require frameless shower doors, windows 18 inches from the ground, windows above the shower/bathtub and glass within a certain distance to the door to use this type of glass.

How can I save money?

Customized cuts will cost a lot more than a standard factory cut.  Consider purchasing a sheet direct from the factory rather than getting a customization.
