Your single source for information on designing, specifying and building with commercial glass.


Placement of a laminated lite within an insulating glass unit is key to how its glazing system will perform. INSLIP and INSLOP are commonly used terms to help designers position laminated glass properly.


Bent & Laminated Glass

In this video, learn how large sheets of glass are bent and laminated for use in insulating glass units (IGUs).

Bird-Friendly Glass

Bird-Friendly Glass

Each year, more than 600 million birds die from collisions with glass in the U.S. alone. Although bird-friendly building regulations continue to increase in North America, glazing options have been limited.

Low-E Glass Demonstration

Low-E Glass Demonstration

This simple demonstration of heat lamps, glass samples and radiometers will give you an understanding of how Solarban® low-emissivity (low-e) glass works for solar control.

Spandrel Glass

Spandrel Glass

There are a wide range of glasses to choose from to meet the needs of any project. Spandrel glass is one such option.

The Benefits of Designing with Reflective Glass

Key benefits to designing buildings with reflective glass.

Designing Glass to Resist Wind and Snow Loads

Accommodating for wind and snow loads is an important upfront consideration during the design and specification phase.

Condensation: What it is. What it means.

Condensation means the IGU is working properly, serving as a thermal barrier between extremes in temperature.

Determining the Right Glass for the Right Acoustics

While glass looks great aesthetically, it also has to meet high performance standards. And an important part of performance relates to acoustics.

Key Elements of an IGU

There are several key elements that impact the performance of an insulated glass unit. These include the primary seal thickness and width, secondary seal width, the spacer and the desiccant.

Spontaneous Breakage of Glass

Information on why glass sometimes breaks in a building without any obvious cause.
