Who We Are
About
Structures Unlimited, Inc.
  For over 40 years, Structures
Unlimited, Inc. has been creating the most energy efficient,
diffuse-light-transmitting skylights, enclosures and buildings with clear spans
over 100 feet. A unique technology of our own self-supporting aluminum
structure is blended with Kalwall® translucent sandwich
panels to form a
total composite system ... pre-engineered, prefabricated and factory
pre-finished for trouble-free, energy-efficient, maintenance-free performance.
The balanced daylighting achieved by these highly corrosion-resistant, ultra
energy-efficient structures opens up a world of design and engineering
possibilities to architects and building designers.
In its latest
evolution of technology, Structures Unlimited has the unique ability to meet
and exceed all energy requirements and thermal codes through the utilization of
newly developed metal panels, traditional highly insulated diffuse-light panels
and the revolutionary Nanogel®-infilled translucent panels - achieving
insulation values up to R-46!
Structures Unlimited skylights and
enclosures stand up to hurricane-force winds and are ideally suited for a range
of applications from shopping malls and airports, to corporate headquarters,
factories, hospitals, swimming pools and even luxury residential
applications.
Structures Unlimited, Inc., is an affiliate of Kalwall
Corporation, and thus, the history of Structures Unlimited goes back to the
founding of Kalwall.
By the end of World War II, Robert Keller had
amassed an impressive background of practical experience in the fields of
laminating and bonding dissimilar materials and working with high-strength,
lightweight construction materials utilized in aircraft manufacturing. Keller
was a pioneer during the "golden age of bonding." The formulation of specialty
high-pressure resins, bonding dissimilar materials and design challenges fueled
Keller's fertile imagination. Keller focused his attention on developing a
proprietary light-transmitting, structural sandwich panel that was lightweight,
inexpensive, insulated, long lasting for the life of the building and that
would give architects complete flexibility with virtually endless design
possibilities. The surface material of Keller's miracle panel was a specially
formulated fiberglass sheet bonded to an aluminum framework. Keller is credited
as the inventor of translucent sandwich panel technology and his company,
Kalwall Corporation, was founded in 1955.

KALWALL
 The
structural integrity of Kalwall's sandwich panel is amazing. Here are 12 men,
weighing a total of 2,757 pounds, standing on a 16-foot panel supported by only
two sawhorses!
You'll note on the right end of the panel are two men,
weighing a total of 526 pounds, standing on the overhang end supported only on
one side! Delicate, look-alike plastic panels cannot support the weight of even
one person. What are the consequences when the wind starts to blow, snow mounts
up, hurricanes blow or an unsuspecting maintenance man walks across a skylight?
There is no substitute for the structural integrity of
Kalwall.
STRUCTURES UNLIMITED, INC.
To meet demands for
spanning large areas such as hotel swimming pools, large central lobbies and
atriums with skylights and skyroofs, and to make possible the creation of
entire translucent structures, a strategic partnership with Kalwall was formed in
1968.
Structures Unlimited, Inc. is the only single-source manufacturer
providing total responsibility from design through installation of structural
skylights, skyroofs, pool enclosures, canopies, walkways and entire structures. Flat or curved,
composite translucent Kalwall sandwich panels are combined with an exclusive
pre-engineered aluminum box beam structural system. This unique pre-engineered
box beam system can span areas in excess of 100 feet, while providing a clean,
finished appearance that is maintenance-free, energy efficient and highly
corrosion resistant. Structures Unlimited, Inc. systems are the world's most
highly insulating, diffuse-light transmitting, structural skylights, skyroofs
and translucent structures.
