Discover how silicone sealants shaped the glass facades of Hudson Yards — one of New York City’s most ambitious developments.
Hudson Yards in New York City is a 28-acre mixed-use development on Manhattan’s Far West Side. Built on a former rail yard, it is the largest private real estate development in U.S. history. Developed by Related Companies, the district is planned for completion between 2024 and 2032.
The development integrates residential, commercial, cultural, and public spaces, including premier retail, luxury residences, The Shed arts center, and public gardens. Sustainability is embedded into the project through onsite power generation, stormwater reuse, direct subway access, and LEED Gold neighborhood certification.
Five of the development’s skyscrapers feature glass curtainwalls sealed with a combination of UltraGlaze™ SSG4600 Structural Silicone Glazing Sealant, SilPruf™ SCS2000 Sealant, and SilPruf™ SCS2350 Sealant, working to ensure long-term durability and weather resistance.
