GLASS TEMPERING BASICS
About Tempered Glass
The process of tempering glass involves rapidly heating then rapidly cooling the product. This transformation makes the glass significantly stronger than non-tempered glass and when broken leaves small, crumbled pieces rather than large, jagged shards that can cause injuries.
Cutting and Fabrication
There are an infinite number of shapes and sizes that can be produced at the Cleer Vision Tempered Glass facility in Elkhart, Indiana. In addition, there are also numerous fabrication options available to enhance glass products such as various edges that can be added or custom holes that can be drilled. It is important to remember that most fabrication options must be performed prior to the tempering process. For example, once glass has been tempered it cannot be cut again or have holes drilled.
FABRICATION
Shapes
With our CNC cutting equipment, it is possible to cut and temper glass pieces as small as 7” X 7” to as large as 70” X 70” to accommodate custom orders in a wide range of sizes. We can happily make almost any shape your industry may require providing edgework or hole drilling as needed for individual job specifications.
If you require shapes that are not square or rectangular, we can fabricate glass in many other custom shapes. All we need are the dimensions and or description in your order. If you have additional questions, contact the Cleer Vision sales development team to discuss the full range of specialty shapes available.
Hole Drilling
Our glass can be drilled before the tempering process creating holes of varying sizes to suit a range of needs. Our capabilities range from a 1/8” hole up to 2 ½” custom drilled holes in the glass.
Special Certifications
We have been independently certified in Guardian’s exclusive Platinum Fabricator program. This program rigorously defines the process measurements, reporting and quality control standards that must be followed to ensure on-going certification within the program. In addition, we are similarly certified by PPG to process their various coated glass products.
We are also certified for ECE regulation 43.01. ECE is the European standard of quality for importing glass in the non-passenger vehicle market. With this certification, Cleer Vision Tempered Glass can process privacy and non-privacy glass in a variety of colors, thicknesses and sizes. If your business includes the export of class N3 vehicles, Cleer Vision Tempered Glass is certified to process your glass.

EDGEWORK
SEAMED EDGE
Standard on all glass edges, seamed edges are free of burrs or sharp pieces that can cause injury but do not have a satin polished look or feel. This option is included in our standard pricing at no additional charge.
PENCIL EDGE
Pencil edging has a more glossy or polished look and feel. This is a more decorative style of edgework for a table top or a shelf.
