Solarban 70 glass, shown here on the National Security Collaboration Center of the University of Texas at San Antonio (UTSA), has a transparent, neutral aesthetic and allows ample visible light to pass through while delivering low interior and exterior reflectance to preserve views.

Vitro Architectural 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 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.

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 percent improvement over using Solarban 70 glass alone. Additional performance benefits of pairing Sungate ThermL glass with Solarban 70 glass include a visible light transmittance (VLT) of 63 per cent and a solar heat gain coefficient (SHGC) of 0.27.

Left to right: Sungate ThermL glass paired with Solarban 60 glass, and Solarban 60 glass alone: due to its colorless and low reflective aesthetic Sungate ThermL glass enhances U-value but does not change the visual characteristics of the IGU.

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 surface provides a U-value of 0.20, which is a 20 percent improvement over using Solarban 60 glass alone. This combination of Sungate ThermL glass with Solarban 60 glass enables a VLT of 69 percent 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.
