Unique Artistic Louvered Facade of New Brooklyn Townhouses Created with Ductal® Ultra-High Performance Concrete

Lafarge North America is contributing to building more beautiful and durable cities with the use of Ductal® UHPC to create a transformative residential development in the historic district of Brooklyn.    

Chicago,  IL

Lafarge North America Inc. 


Nestled between the famous Manhattan and Brooklyn Bridges, the historic district of Brooklyn, New York, has undergone a major makeover since its days as a shipping port. Known as the area Down Under the Manhattan Bridge Overpass (DUMBO), the neighborhood has evolved in recent decades from a once desolate landscape of forgotten 19th-century warehouses to a bustling, mixed-use area that now thrives with galleries, shops, theatres and lofts.


The transformation of DUMBO continues this year with the completion of a new six-story residential development on a former warehouse site at the corner of Pearl and Water Streets. Designed and created by local developer Alloy, the innovative building has energy-efficient systems and a high-performance envelope surrounded by a beautiful louvered façade panel system made with Ductal® ultra-high- performance concrete (UHPC) from Lafarge.


Blended with high carbon metallic or polyvinyl alcohol (PVA) fibers, Ductal® offers superior strength, ductility, durability and aesthetic design flexibility. This allows designers to create thinner façade panels with longer spans that are lighter and more graceful in geometry and form, while providing improved durability and impermeability against corrosion, abrasion and impact. Furthermore, the product's high fluidity allows it to be poured into extremely complex and varied forms.


The facade of the five luxurious DUMBO townhouses comprises five rows of one-inch-thick Ductal® fins with either windows or more Ductal® behind them. Produced by Gate Precast, each of the 18-foot-wide by 11-foot-tall Ductal® louvered panels contains a series of ribs and no rebar. A series of stainless steel rods connects the backs of the 32 panels directly to a partially grouted concrete masonry unit wall system.


According to Kelly Henry, Lafarge Architectural Project Manager-Ductal®, all of the windows and connections aligned perfectly, facilitating a relatively easy and successful installation process. "The developer was extremely impressed with the precision, detail and quality of the panels produced by Gate Precast, which cover a total surface area of 8,650 square feet," she said. "In an old neighborhood built largely with brick, the thin, clean lines of the Ductal® fins provide a sleek design element with a custom patina color to create an elegant contextual residential development in the DUMBO district of Brooklyn."
