What Is a Point-Supported Glass System, and Where Does It Work Best?

When designers and builders want glass to be the main feature of a building, a point-supported glass system is often how they do it. This system lets you create large, unbroken glass surfaces without bulky metal frames getting in the way. The result is a clean, open look that lets in light and makes a strong first impression. If you own or manage a commercial property and want to understand what point-supported glass is and whether it fits your project, here’s a plain-language breakdown.

What Is a Point-Supported Glass System?

A point-supported glass system holds large glass panels in place using small metal fittings that attach directly to the glass through pre-drilled holes. Instead of a frame running around the edge of every panel, only a few small connection points are visible. Those fittings transfer the weight and wind pressure to a steel or cable structure behind the glass. The end result is a glass surface that looks almost frameless. You see the glass, but not the hardware holding it up.

Since holes need to be drilled into the glass before it’s treated, all glass in a point-supported glass system must be tempered glass. Tempered glass is much stronger than regular glass, which makes it the right choice for large, exposed panels that handle real structural loads.

How Is It Different From a Curtain Wall?

A curtain wall is another common way to cover the outside of a commercial building in glass. It uses a visible metal grid — rows and columns of aluminum framing — to hold each glass panel in place. The grid is easy to see from the street and gives the building a structured, modular look.

A point-supported glass system removes most of that visible framing. The glass panels are larger, the connection points are small, and the overall look is much more open and seamless. If the goal is maximum transparency and visual impact, point-supported glass achieves that in a way a curtain wall can’t.

Where Does a Point-Supported Glass System Work Best?

Point-supported glass is a strong choice any time a project calls for large, open glass surfaces with a clean, modern look. The most common uses include:

Building entrances and canopies: A glass canopy or entrance wall held by a point-supported system makes an immediate impression without blocking the view of the entry. This is one of the most popular uses in commercial and institutional buildings across Southern California.

Lobby walls and interior partitions: Inside a building, glass wall installations using point-fixed glass create open, bright spaces that still provide some separation between areas. Corporate offices, hotels, and retail spaces use this approach to keep things feeling connected while staying organized.

Skylights and overhead glass: When glass needs to go overhead without a heavy frame blocking light, point-fixed systems offer a safe way to make that work. Special laminated tempered glass is required for these applications to meet safety codes.

Commercial facades: For storefronts and mixed-use buildings where the exterior is part of the brand experience, a point-supported system creates a level of visual quality that standard framed systems don’t.

What Goes Into Building a Point-Supported Glass System?

Every point-supported glass system is custom-built for its specific project. The size and thickness of each glass panel, the spacing of the connection points, and the structure behind the glass all have to be designed around the site’s specific conditions, including wind loads and earthquake requirements.

Golden Glass works directly with project architects and structural engineers to make sure every system is both safe and true to the original design vision. We handle everything from engineering coordination through final installation.
