DFB manufactures and installs custom window and wall treatments for the commercial and high-end residential markets. We work directly with the architect, design and construction community in New York City to build spaces with unique personalities.

By manufacturing everything within NYC, DFB can provide the close budget, logistics and installation support to ensure a smooth project even under tight deadlines. Our factory is located minutes from mid-town in Long Island City.

DFB is geared to handle both small and large projects due to our scalable manufacturing processes. Because we make everything we sell, we directly support all of our products with a simple and comprehensive warranty.


Vitruv is low emitting, seamless, easy to maintain or repair, and will often contribute toward points for LEED certification.
