In the 1960s construction contractors used space heaters and a combination of wood framing and plastic tarps to enclose concrete and masonry work. It was crude and inefficient, but it kept crews working though the cold winter months.

Ron Kellogg, a construction contractor in Fremont, Nebraska, frustrated that the enclosures were inefficient and unreliable, developed a reusable steel framed panel system with a fiberglass insert.  It worked so well that he began marketing the enclosure panels to other contractors.
