Crews have completed the installation of denim insulation on the second floor of the Woolworth building. Made from recycled denim, this eco-friendly material provides safe, high-performance insulation that supports both comfort and sustainability. Each section is fitted carefully between the metal framing to ensure complete coverage and sound control for future office tenants. This installation marks an important step before the walls are enclosed with drywall, creating an insulated and energy-efficient environment within this historic structure.
