1660 Madison

Rising above Madison Avenue in Manhattan, 1660 Madison is a high-rise hospitality development that blends urban density with advanced building performance. Outfitted with INTUS Windows double glass systems using both annealed and tempered glazing (22mm and 24mm), the project delivers impressive thermal insulation (U-value 0.25) and robust noise reduction (STC 32 / OITC 26). With low solar heat gain (SHGC 0.13) and visual transmittance of 0.42, these energy-efficient windows help maintain interior comfort while minimizing energy load. Installed via mounting brackets, these high-performance commercial windows are engineered for durability, performance, and comfort in demanding city environments.
