A fan-folded insulating board laminate comprises an extended length of synthetic resin foam board having longitudinal edges and protective skins adhered to each surface of the foam board. Reinforcing strips are spaced along both of the longitudinal edges of the laminate and are bonded to both of the skins. They extend about the longitudinal edges, and the laminate has a series of longitudinally spaced cuts through the board and alternately through one of the protective skins. The uncut skin and strip act as a hinge between adjacent sections of the board to enable fan-folding of the laminate.
