Systems are interlocking, load-bearing
composite 4x8 panels made of
polystyrene and galvanized steel. With
electrical conduits, window and door
openings molded in, these custom
panels weigh 45 pounds each. Shiplap
joints are connected on site. The
tight-fitting joints reduce air flow, and
the insulation values are higher than
for traditional stud systems. The
manufacturer, RADVA Corporation,
will provide training and assistance in
construction. They can customize
shapes and sizes and tailor panels to
accommodate special wiring, and
window and door openings. Contact
