This structural wall system uses 1x3-foot reinforced concrete planks 1 « to 2 inches thick set in parallel rows about 5 inches apart. The cavity between them is filled with either poured urethane foam or concrete. For more strength, concrete bond beams are added at top and bottom, with vertical columns connecting wherever structural stress is greater than normal.

The 3-foot-long planks are cast in reinforced elastomeric molds, designed by the manufacturer to provide any exterior textural surface effect desired. The wall system in which they are used is reportedly geared to meet the overseas needs in housing and light commercial construction but can also be adapted for the U.S. market.

A typical completed wall is 8 inches thick, has 5 inches of foam, with an R-value of about 36.
