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.

FSGLASSTM offers a broad selection of both reflective and Low-E coatings. Our coatings can be applied to clear glass substrates. In addition, a digital print or silk-screen pattern can be applied to the same surface as the coating for excellent solar performance and appearance. 

Surface Designation
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 FSG coatings are located on the #2 surface.
