Reliance™-TC LT

Reliance™-TC LT is the ultimate curtain wall solution, combining industry-leading thermal performance with premium aesthetics. The lightweight, easy to install Reliance™-TC LT offers greater cost efficiency and a slim, 2” sightline that provides expansive views while still delivering the highest levels of thermal performance and seismic resilience.

This LEED-eligible double-pane curtain wall has a U-factor of 0.29, setting new standards in thermal performance, making it ideal for IECC Zones 4-8. A dual-finish option adds to its design flexibility and aesthetic appeal with a twin span application, enabling use across multiple floors. And because it’s from the Reliance™ family, installers can leverage previous fabrication and installation experience from OBE – the single source solution for metal and glass.
