The F Series Capped Curtain Wall is a high-performance stick-built façade solution designed for strength, precision, and thermal efficiency. Available in 2″ (F50++) and 2 3/8″ (F60++) mullion options, this system uses shear block construction with identical mullion and transom profiles for streamlined fabrication and installation.
A proprietary continuous interior gasket, paired with an extruded foam insulator, enables the F Series to achieve ultra-high thermal performance, even with glass thicknesses up to 1 7/8″. Multiple configuration options make it suitable for a wide range of architectural applications, from low- to high-rise projects.
