Coatings are thin layers of metal applied to glass to improve solar performance. The first coatings utilized on building facades were reflective coatings which provide a mirror-like appearance and reduce solar heat gain by reflecting the sun’s energy away from the building.
Today, the most popular coatings applied to glass are low-emissivity (Low-E) coatings. Coatings with low-emissivity properties have low heat transfer properties and offer higher light transmission than traditional reflective coatings.
Viracon offers a broad selection of both reflective and Low-E coatings. Our coatings can be applied to clear or tinted glass substrates. In addition, a silk-screen pattern can be applied to the same surface as the coating for excellent solar performance and appearance.
Appearance and Performance
The specific coating needed for a given project is typically dictated by a required solar performance or a desired appearance. Viracon’s “Search By Appearance” and “Search By Performance” tools simplify the process of selecting specific glass coating and color combinations.
When describing glass products there are industry standard recommended surface designations. Each ply of glass has two surfaces. The surface facing the exterior of the building is referred to as surface #1, the back of this glass ply is surface #2. For glass units with multiple glass plies, there could be 6 or more surfaces. Shown here are a few examples:
For cooling dominated buildings, the best solar performance is achieved when the coating is applied to the #2 surface, therefore Viracon coatings are located on the #2 surface.
Viracon utilizes an alphanumeric code for each coated glass product. The code designates the coating as well as the glass color the coating is applied to. This nomenclature is meant to aid in specifying our fabricated glass products however is not enough on its own to clearly identify the full glass unit. In a specification, it is important to include the Viracon nomenclature along with an outline including each component of the glass unit.
The first portion of the code represents the coating family. Examples of coating families include VE, VRE, and VS. 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. Within each family, the coatings available have varying degrees of light transmittance. In our nomenclature, this is represented by the number following the dash.
The number between the Viracon coating family and the nominal light transmittance of the coating is the color of glass the coating is applied to.
