Glass Office Chair Mats

Tempered glass is stronger than standard glass and does not shatter into large shards when broken. Tempered glass is often used in applications where using standard glass could pose a potential danger. Manufactured through a process of extreme heating and rapid cooling, tempered glass is much harder and stronger than normal glass.

You will need to submit a sketch or drawing with dimensions. If your shape is basically a rectangular shape, use the rounded corners shape. You will have an option in the online quote in a section called “fabrication “. Here you can select that you have custom cutouts and it will allow you to upload your sketch. You can also use the Irregular / Any Other Shape and you can upload your sketch here.

The industry-wide accepted tolerance on 1/8″, 3/16″, and 1/4″ is +/- 1/16″. This includes side shifts on laminated products. The industry-wide accepted tolerance on 3/8″ and 1/2″, +/- 1/8″. This includes side shifts on laminated products.

Glass thicknesses are shown as a Nominal Thickness, meaning “in name only”, used solely for identification. These are commonly listed as 1/8″, 5/32″, 1/8″, 3/16″, 1/4″, 3/8″, and 1/2″. The nominal size may not match the exact thickness but will be within the acceptable industry-wide thickness range and can correspond to a large number of highly standardized dimensions and tolerances.

It is simple to measure a radius by using our radius measurement tool. Download the tool by clicking here. Print the tool. When printing please make sure page scaling is set to none. To verify you have printed the tool to the correct scale measure the 1″ Scale Line at the bottom of the page. It should measure out to exactly 1″. If it does not measure correctly please check your printer settings.

The correct radius will fill the entire curved area on the template.

How do I know if I need edgework?
A “seamed” edge is one that has been lightly sanded to remove any sharp burrs. Glass with a seamed edge is safe to handle but is not decorative. It is our standard finish and is available at no extra charge. We will never send out glass with sharp edges that you could not handle safely without being cut.

The seamed edge is recommended for all applications in which the edges of the glass are not exposed.

For example, if your glass will be installed into the frame of a fireplace door and no one will see the edges once the glass has been installed, a seamed edge is all you need.

For glass chair mats, you may want to consider upgrading to a more finished/decorated edge.
