Structural Grid Cores
Kalwall translucent structural sandwich panels include a grid core composed of a series of interlocking I-beams that are either all aluminum or aluminum+FRP thermally broken I-beams. Standard structural grid cores include: shoji + reverse shoji. Popular optional and custom grids for facades only include: tuckerman, “Verti-Kal™” + ladder, plank + plank reverse, root + branch, and many others. Please inquire about additional custom grid core configurations.
concept diagram
The diagram above shows the components that form the structural grid core. Although all framing elements are either standard or thermally broken I-beams, their configuration is significant. Many grid pattern compositions are possible but each has it own maximum spans and panel module length. Standard panel widths are 4′ and 5′ although custom widths up to 5′ are also possible.

Maximum panel module sizes vary depending on structural grid core patterns, individual cell area and panel thickness. Panel module engineering is determined by design load critera and code requirements.
