Vitro Architectural Glass Unveils New Interior Low-Emissivity Coating, Sungate ThermL Glass

Vitro Architectural Glass (formerly PPG Glass) has launched Sungate ThermL glass, a new low-emissivity (low-e) coating engineered for use on the interior surface of a typical one-inch insulating glass unit (IGU) that reduces heat transfer and dramatically improves U-values when paired with a Solarban solar control low-e glass by Vitro on the second surface.

“We’re pleased to unveil Sungate ThermL glass, our new U-value enhancing low-e coating that enables superior thermal performance without changing the visual characteristics of the IGU because of its colorless and low reflective aesthetic,” said Erin Casci, Product Manager for MSVD Coated Products, Vitro Architectural Glass. “What’s unique about Sungate ThermL glass is that it gives the same look and feel as uncoated glass while maintaining high visible light transmittance (VLT) and enabling even more high-performance configurations for today’s glazing contractors. It’s another example of Vitro’s continued commitment to providing the most sustainable solutions in the glass industry.”


When Sungate ThermL glass is paired in a one-inch IGU with a half-inch airspace with argon and Solarban 70 glass on the second surface, the U-value is 0.19, a 21% improvement over using Solarban 70 glass alone. Additional performance benefits of pairing Sungate ThermL glass with Solarban 70 glass include a VLT of 63% and a solar heat gain coefficient (SHGC) of 0.27.

In a one-inch IGU with a half-inch airspace with argon, Solarban 60 glass on the second surface and Sungate ThermL glass on the fourth surfacer provides a U-value of 0.20, which is a 20% improvement over using Solarban 60 glass alone. This combination of Sungate ThermL glass with Solarban 60 glass enables a VLT of 69% and SHGC of 0.38.

Available now exclusively through Vitro Authorized and Vitro Certified fabricators, Sungate ThermL glass is ideal wherever increased insulation performance is needed. Another benefit of Sungate ThermL glass is that the coating is as durable and resistant to mechanical abrasion as uncoated glass.
