REQUEST SAMPLE

Viracon’s architectural glass products are divided into three types:

Insulating and laminated products both offer a variety of configurations and can also be combined into insulating laminated units.

Once you’ve selected a specific configuration, be sure to explore each component that goes into fabricating it. Viracon has a vast selection of coatings, glass substrates and other components. You will want to select the most appropriate options for your application before developing a glass specification.

In addition to the components needed to fabricate a glass type, there are a multiple enhancements available to further customize your glass selection. Enhancements offer options for enhancing the performance, appearance or a combination of both.

Viracon Product Descriptions

Viracon glass products have a primary description and a detailed description. We recommend including both descriptions in your glass specification. In addition, these descriptions appear on samples, quotes and product tags.

Insulating

How to Interpret the Primary Description

The key attributes identified within the primary description are thickness, exterior glass ply and configuration.

1"

Thickness

VRE1-43

Exterior Glass Ply

Insulating

Configuration

 

Thickness

The nominal value of each glass ply, spacer and interlayer added together, this is listed as a whole number and fraction in inches or as a whole number in millimeters.

Exterior Glass Ply

This describes the exterior glass substrate color and coating.

Configuration

This represents the common industry name for the assembly. For example, a single ply of glass is Monolithic, two plies with an interlayer is Laminated and, two plies with a spacer is Insulating. Click on any configuration listed along the left menu to learn more.

When the exterior glass ply is uncoated, the glass substrate color name is used; there is no alphanumeric code.

When the exterior glass ply is coated, an alphanumeric code is used to identify the glass substrate color and the coating applied to the substrate.

Coating Light Transmittance

Coating Family

The family is a label developed by Viracon and typically groups coatings that have something in common. Any coating family with the letter 'E' in the code is a Viracon Low-E Coating and those without an 'E' are Viracon Reflective Coatings.

Glass Substrate

A number assigned by Viracon to each glass substrate color. The list of colors and the assigned number can be found under Glass Substrates.

Dash

This is used to separate the nominal light transmittance value from the remainder of the product code.

Coating Light Transmittance

The nominal amount of visible light transmitted through the coating. This is not a precise value but, rather, a relative value to assist in comparing and selecting coatings.

 

Additional Considerations

The primary description does not identify individual components such as specific glass ply thicknesses, spacer thickness or inboard glass color. The detailed description is needed to fully describe the glass unit.

Within each coating family, there are multiple individual coatings. These individual coatings are identified by the coating family followed by a dash and the nominal light transmittance, i.e. VRE-43, VE-2M, VNE-63. This identification follows the glass substrate information in the detailed description, i.e. 1/4” Clear with VRE-43 #2, 1/4” Gray with VRE-43 #2. Additional information about the available coatings can be found under Coatings.
