Tempered glass is a flat glass product which has undergone heat treatment. It is heated to approximately 1,112°F (600°C), then cooled rapidly using jets of air.
Fully tempered glass is used in many applications because of its safety characteristics. It can satisfy federal, state and local building code requirements for safety glazing in such applications as doors, side lights, showers, tub enclosures, and interior partitions. It is also used in storm doors, patio-door assemblies, and escalator and stairway balustrades.
We can cut to precise measurements, drill, edge, and make any other necessary customizations to get started on your perfect piece of flat glass.

We offer a variety of frameless glass products. The beveled edges are created by cutting and polishing the glass edges to a precise angle and size in order to achieve aesthetic excellence. But the bevel has a very useful practical purpose — if a sharp edge is nice and leveled off as a slope, you’re not going to get cut. You can use beveled glass in decorative windows, doors (as a window insert), tabletops, cabinet doors, or as a purely decorative wall hanging pieces or artwork. Some homeowners also use beveled pieces in ornate leaded glass windows. Along with translucent (clear) glass, you can also choose a beveled style for mirrors.

Flat polished edges are the most popular choice of edgework, aside from the simple seamed edge. If the glass in your project is frameless or will not have some type of border that hides the edges, then polished edges are great for that option. This polish is made by grinding down the edges of the glass and then buffering them to leave a clear finish. It’s a straight cut edge that is polished with a slight 45˚ angle on the top and bottom. For a decorative look, customers can select the 1/8” bevel edge option to achieve an aesthetically appealing, even, and glossy finish.

Depending on your type of project, you may need to have holes drilled in the glass. Let’s say it is a hole in a glass door for the knob or the holes in the glass railing system to fit the hardware. We can drill holes of different diameters for whatever you need.

We can make cutouts for multiple forms with accurate processing. Interior, edge, and corner cutouts can be made to the desired size and form according to your specifications. We source only the highest-quality glass for our custom glass products. This means we can be sure of the quality of each custom-cut glass product we make.

Double glazing is designed to limit heat lost through conduction within the glass by inserting an insulating space of air between the two sheets of glass. These are most often used in residential window applications. Custom-made to your specifications. Since thermal insulation is increased by the presence of an air space, the next stage is triple glazing – glazings made up of three sheets of glass separated by two spaces.
