The Kalwall system puts translucent unitized panels into an aluminum framing system.

The result is a translucent panel system that has great flexibility of design, excellent spanning ability and good insulation and shading values while admitting natural spectrum light.

Materials

The Panel -

Facesheet - Developed and produced by Kalwall, this facesheet incorporates features not available from any other manufacturer. Sheets are manufactured up to 5' in width and up to 20' in length.
Features include:

UV Stable resins resist color change over the life of the panel

 

A fiberglass "Veil" integrated into the surface of the exterior facesheet keeps the ends of the reinforcing fibers from protruding through the surface as the panel wears over time. A 25 year guarantee against "Fiber Bloom" is issued with confidence.

 

A variety of facesheets offer great durability and can take impacts up to 230 Ft. Lbs. (60 Ft. Lbs. standard)

•  

Grid - Aluminum "I" beams form a grid pattern from 8" x 8" to 12" x 24". The "I" beams are continuous in the direction of the span. The cross span "I" beams are notched and fitted to interlock with the spanning grid. Also available are composite Thermal Break "I" beams for greater insulation values without any loss of structural abilities.

Adhesive - In a sense the adhesive is the heart of the system. Extremely strong with a calculated bit of yield, the proprietary adhesive makes the panel a unit and combines the strengths of the facesheet with the strengths of the grid core to produce an extremely strong durable panel.

The Composite Panel - As a unit the panel provides a light transmitting building envelope with good insulation and strength values.

• - Capable of spanning 20+ feet as a roof or wall
• - Capable of being curved as a vault or wall
• - Can be produced integrating operable or fixed glass windows
• - Admits less than 1% of U.V. wavelengths of light, protecting items while lighting them with the full spectrum of visible light.

The Framing System -

Frame - Aluminum extrusions form a perimeter clamping system that allows some movement while maintaining a watertight seal.

 

 

Battens - Clamping battens join panels into large expanses

Lighting Quality - A distinct feature of the Kalwall system is the Quality of the light filling the interior space. Randomly oriented glass fibers in the exterior facesheet diffuse the incoming light which then passes through the interior facesheet being diffused even more. The resultant light is very even with no "hot spots" or contrasting shadows. "Museum Quality" is a term often used to describe the result. The fact that almost no U.V. rays enter the space makes this description very apt.
