Sungate ThermL Glass

Sungate ThermL glass by Vitro is an innovative low-emissivity (low-e) coating designed for the interior surface of a standard one-inch insulating glass unit (IGU). This advanced coating significantly reduces heat transfer and dramatically improves U-values when paired with Solarban solar control low-e glass by Vitro on the second surface. The new technology aims to address the growing demand for high-performance glazing solutions that deliver superior energy efficiency without sacrificing aesthetic appeal.

2025 PIA Judge's Comment

"Sungate ThermL represents one of the clearest material innovations in the glazing sector this year. By adding a neutral fourth-surface low-e coating to standard IGUs, the system increases U-value performance by over 20% without sacrificing clarity or requiring triple glazing. It’s an elegant, cost-efficient move toward higher thermal performance and lower operational carbon - precisely the type of incremental-but-impactful innovation the market needs."
