Strategic Partners

Structures Unlimited works closely with several strategic partners to offer customers a broad spectrum of services, and leverage design technology and advances in material science.

Kalwall Corporation has been setting the industry standard for diffuse natural lighting systems since it was introduced globally at the 1958 World’s Fair in Brussels and, again, at the 1964 World’s Fair in New York. Much has changed since then, but the beauty, efficiency and ruggedness of Kalwall systems have not. Neither has Kalwall’s commitment to fine craftsmanship, custom work and continuing advances in technology. Kalwall is recognized for its innovations in window designs that provide a more predictable, better quality of usable natural light with superior thermal properties and best in industry solar heat gain control. Kalwall is a key component in all projects by Structures Unlimited, Inc.
