Unitized & Stick Curtain Wall

One of the most recognizable components of the building is the curtain wall. In addition to being an eye-catching architectural element, the curtain wall is highly functional and designed to resist wind loads, air and water infiltrations and building sway induced by wind and seismic forces.

Larson Engineering has over 35 years of integrity and innovation in structural design for curtain wall systems. We have provided structural design for some of the most elegant and prestigious curtain wall systems in the world.
