Installing a fully unitized curtain wall at 412 West 15th Street involved seamlessly integrating a domestic louver system within the European unitized curtain wall system while meeting tight time constraints. In order to complete the final two rows of units at the top of the building where there were no floors, Walsh Glass & Metal devised a project-specific crane for setting the units. Collaborative efforts throughout the life of the project between the general contractor Triton Construction, architectural consultants Gilsanz Murray Steficek, and Walsh Glass & Metal helped to ensure an outstanding outcome.
