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.

Pro and Cons of Gas-Filled Insulating Glass Units

Determining whether or not to use gas versus air in an insulated glass unit (IGU).

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.

How Glass Is Made – From the Batch House to the Lehr

The process of how glass is made, starting with a simple comination of ingredients, to large sweeping glass panels.

How Glass Is Made – From Cutting to Low-e Coatings

The process of how glass is made, starting with a simple comination of ingredients, to large sweeping glass panels.

Glass Education Thermal Stress

Preventing Thermal Stress Breakage

Selecting the right glass to meet a project’s thermal loads.

What Glass Does with Solar Energy

The solar energy spectrum and the different ways glass responds to light.

North American Glass Channel

Different processes and channel partners are involved in the production of commercial glass.

Glass Education Low-E

How Low-e Glass Works

Performance through passive and solar control low-e coatings.

Low-e Coatings Work Like a Thermos Lining

For an easy way to understand how low-e glass coatings help keep rooms comfortable, simply look at how a thermos works.

Low-e Coatings Thickness

Low-e coatings are 500 times as thin as a human hair, yet have a tremendous impact on a building’s overall energy efficiency.

Glass Education Large Glass IGU

Specifying Large Insulated Glass Units

Factors to consider when specifying large insulating glass units.

Glass Education Top Design Considerations

Top Design Considerations

Glass requires special considerations during the specification process.

Float Glass Process

A multi-step glass manufacturing process where liquid glass is formed by “floating” it on molten metal.

Glass Education Heated

Heat Strengthened vs. Tempered Glass

The difference between types of heated glass.

Solar Energy Spectrum

Understanding the solar energy spectrum is the first step in understanding how low-e coatings work.
