CASE STUDY
Harmonizing Heights: Innovation at Lower Manhattan Skyscraper with Modernfold Acousti-Seal
Nestled amidst the bustling landscape of lower Manhattan between Fulton Street and Wall Street stations, 140 Broadway stands tall as an iconic symbol of architectural prowess. Owned by Union Investment since 2004, with exclusive U.S. advisory services provided by Metzler Real Estate, this 50-story skyscraper has undergone multiple refurbishments to emerge as a beacon of modernity in premium NYC office spaces, including updated electrical and building systems, on-site generators, refreshed lobbies, and new amenity spaces for tenants.

Among its latest transformations involves our installation of Modernfold Acousti-Seal Legacy paired panel units, strategically enhancing the building’s meeting rooms with cutting-edge space management solutions. Spearheaded by global architectural firm Gensler and executed by our contractor, L&K Partners Inc, ModernfoldStyles completed this installation with a harmonious blend of functionality and aesthetic appeal.


The Modernfold Acousti-Seal Legacy units hang from 4-wheel ball-bearing trolleys and glide effortlessly through Modernfold’s #17 steel track.


Its closure method utilized an expandable panel, providing the flexibility to adapt to diverse spatial needs. With a considerable panel thickness of 3”, providing a 52 STC, the space can be used for large events or individual meeting rooms without sound interference.


To further contribute to its acoustic control, the panels were constructed with fixed top seals, Sure-set Manuel 2” bottom seals, and 1.5” vinyl bulb seals at the partition’s intersections.



The panel skins were made out of steel, hanging at 11 lbs. Coupled with its dark bronze hinges and trim, the movable partition creates a sophisticated visual appeal that seamlessly integrates with the building’s aesthetic. The panel finish, adorned with Carnegie and Xorel Mojave Matte 6091-503 featuring heavy acrylic backing for direct glue application, not only enhances the space management solution’s appearance but also underscores our dedication to durable and high-quality materials.


Adding to the user experience, ADA-compliant pass doors were incorporated to offer direct access to the divided rooms, exemplifying ModernfoldStyles’ commitment to user-friendly design.
