Insulspan manufactures expanded-polystyrene structural insulated panels for walls, roofs and floors, serving custom homes, commercial buildings and other high-performance envelopes. The company supports architects, designers, builders and owners with panel planning, technical literature and fabrication from approved drawings.

Projects can use panels as a complete shell or alongside timber and conventional structural systems. Buyers should confirm engineering seals, shop drawings, splines and fasteners, freight, installation training and locally supplied finishes.
