The Next Generation of Curtainwall Thermal Performance

ThermTek™ high-performance curtainwall systems were engineered in response to the significant challenges the façade industry is facing with the increasingly stringent building energy codes. Our patent-pending solutions are versatile, thermally advanced, suitable for a wide range of façade applications, and allow for seamless transitions between systems while maintaining continuous air and water lines.

With ThermTek, higher thermal performance means more glass and more daylighting for today’s buildings.
