Short Wave and Long Wave Energy

Understanding the solar energy spectrum is key to understanding glass coatings. Glass coatings affect the way the different parts of the solar spectrum are absorbed into, transmitted through or reflected off of glass, all of which factor into the glass' energy efficiency.

Heat-Treated Glass: It's All About the Pressure

When designing with large expanses of glass, it is critical to know when the glass may need to be heat-treated for durability and/or safety. The type of processing required—heat strengthening or tempering—depends on the specific application.

Designing Glass to Resist Wind and Snow Loads

Accommodating for wind and snow is one of the important upfront considerations in the design and specification process. There is a multi-step process that must be undertaken to help ensure the glass in your project is able to resist these loads.

Determining the Right Glass for the Right Acoustics

While glass looks great aesthetically, it also has to meet high performance standards. An important part of performance relates to acoustics, whether it’s large, dramatic panels used for the exterior of a building, or smaller panels used to create interior partitions. When designing a project there are a number of sound-related factors you need to understand and take into consideration, including:

Nickel Sulfide and Spontaneous Breakage

Sometimes glass breaks in a building without any obvious cause. When this occurs, it could be due to glass edge damage or surface damage from handling and glazing that then weakens the glass during high winds, building or framing system movement, vandalism or a specific type of inclusion inside the glass. There are more than 50 types of inclusions in float glass, and while the most widely discussed is a nickel sulfide stone, this type of inclusion actually occurs very rarely.

Fun Glass Facts

 

The first insulating glass units were developed in 1945 for the Pullman Car Company in Butler, PA.

 

A standard float tank can produce glass 24 hours/7 days a week for up to 15 years before it needs to be rebuilt.
