Silver Towers

The replacement of 1,662 windows and 1,432 PTACs was completed as part of this project at Silver Towers, a three-building residential complex in Greenwich Village. The 30-story freestanding poured-in-place concrete structures were designed by I.M. Pei and are individually landmarked. A new wall assembly was installed, which included new replacement windows and glazing, sound attenuated PTACs, gypsum board walls, and limp mass barriers. The work required acoustical testing to determine an appropriate exterior wall assembly package that met both the local environmental designation requirements and the New York City Landmarks Preservation Commission's guidelines.
