1 Architectural Walls

2 Nello Wall Systems designs, manufactures, and installs Architectural Walls, and has been providing environmentally friendly, flexible office solutions for over 35 years. Nello Architectural Walls set the standard for sustainability; the first Nello wall was designed by Frank Gehry in 973, it has since been reconfigured and reused many different times, and is still in use today. Nello is a Veteran Owned Small Business located just north of the Washington, DC Capital Beltway. Nello has the experience, knowledge, and low-overhead, competitive-cost advantage to make your project a success.

3 Nello s glass Architectural Walls strike the perfect balance between storefront-style visual impact and long term ease of mobility. Interior segmented fabric walls improve sound absorption while providing true tackable functionality.

4 Whether creating a public-facing customer service space, a staff conference room, or a suite of executive offices, Nello s glass Architectural Walls can be configured in a limitless array of colors, patterns, and textures to suit any need.

5 Wood veneer panels can be used to accent or define a dramatic and powerful private space. Painted MDF, (available formaldehyde-free, with high-recycled content), is a durable solution for high traffic areas. Tackable-fabric, self-healing walls epitomize ergonomic efficiency for taskoriented desk spaces. In any finish format, Nello s Architectural Walls represent the best return on investment for a flexible, ever-evolving office environment.

6 Nello Architectural Walls offer your design team multiple opportunities for LEED Credits. In fact, at the GSA Headquarters Swingspace, Nello Walls contributed to a LEED Platinum certification, (as shown). Beyond the LEED initiative, Nello Architectural Walls have repeatedly been chosen by forward-looking designers seeking the most sustainable solution for an easily reconfigurable office floor plan. Nello has consistently proven its ability to successfully complete large scale environmentally sensitive projects while exceeding budget and lead-time expectations.

7 Nello strives to continually improve, refine, and even reengineer its Architectural Walls so that it can deliver the best product to its customers. If you have a unique design vision in mind, Nello is always intrigued by, and well positioned to excel at, Build to Spec Opportunities.
