Components Glass Substrates.
Glass substrates are the individual plies of glass used to fabricate glass units. They are available in a variety of thicknesses and can have Viracon’s Low-E coatings and DigitalDistinctions® or silkscreen printing applied. Contact us to explore substrate options.

Viracon Nomenclature Specifying Substrates.
Viracon utilizes an alphanumeric code for the substrate + coating to specify the outboard lite.
A 2-digit performance code represents the VLT of the coated substrate. If the performance code is 4-digits, VLT and SHGC respectively are represented.
Coating and Substrate Identifier

Coating Family
The first portion of the code represents the coating family.
Coating VLT Performance
In our specification, the available coatings have varying degrees of Visible Light Transmittance (VLT) represented by the 2-digit number following the dash.
If the number following the dash has 4-digits, the second 2 digits represent SHGC on Clear glass.
Coating Performance
47 = 47% VLT
25 = 0.25 SHGC
25 = 0.25 SHGC
Substrate Glass Color
The glass substrate color number, shown above, appears after the coating family and before the dash in our nomenclature.

Design Considerations
Specify each ply within the glass configuration
- In units with multiple glass plies, it is important to specify the specific glass substrate for each ply
- Typically, only one ply of the fabricated glass unit is tinted while the other ply remains Clear
Performance
Glass tinted substrate placement for improved performance
- The tinted ply should be placed to the exterior for best performance, specifically, to reduce the SHGC and reflectivity
- Laminated exterior glass is an exception. The SHGC can be improved by moving the tinted ply to the inboard lite position
