How much a 4x8 sheet of foam board costs depends on type, thickness, and brand, with prices varying by location and retailer. For common rigid foam insulation boards, a 4x8 sheet of 1 inch thick expanded polystyrene EPS typically costs $15 to $25, extruded polystyrene XPS like Owens Corning Foamular or Dow Styrofoam costs $20 to $40 for 1 inch thickness, and thicker boards cost more, with 2 inch thick XPS costing $35 to $60 per sheet. Polyiso foam boards with foil facing cost $25 to $50 for 1 inch. Craft foam board like foam core board for presentations, 4x8 sheet costs $20 to $35. At Home Depot or Lowes, prices fluctuate with supply and demand. For example, 4x8 sheet of 1 inch thick white EPS foam board might be around $20, while pink or blue XPS foam board of same size and thickness is around $30. Thicker 2 inch boards are roughly double. So expect $15 to $60 per 4x8 sheet depending on material and thickness, with insulation foam boards being most common.
