The CW1100 is a high-performance stick-built curtain wall system engineered for mid-rise and high-rise commercial, institutional, and mixed-use building facades. Field-assembled from individual aluminum mullions and transoms anchored directly to the building structure, the CW1100 offers maximum flexibility for complex facade geometries, varying floor-to-floor heights, and custom module sizes, while delivering outstanding thermal performance. Sight lines are nominally 2½", presenting a clean, attractive appearance.
