About Us

Porter Corp, founded in 1964 is a design, engineering and manufacturing company focusing on exterior structures and insulated building envelopes. Porter Corp was one of the first producers of SIPs (Structural Insulated Panels). Bill Porter’s venture in SIPs was an outgrowth of his experience in the marine industry where he learned that one of the best ways to build an economical, structural boat bottom was with a plastic foam core in sandwich construction with fiberglass. He was also one of the founding members of SIPA (Structural Insulated Panels Association).
