Professional model builders prefer Gatorfoam to wood for fabricating a wide variety of structures. Gatorfoam has a 1/32 inch thick wood-fiber veneer called Luxcell that is laminated with waterproof adhesive to both sides of a polystyrene foam core. The resulting 3/16 inch thick panel is strong, light-weight and warp-resistant. Gatorfoam cuts easily with a modeler's knife or with miniature power saws. Its smooth finish is compatible with all types of paints and adhesives, and self-stick textured building papers adhere perfectly. 12" x 18" x 3/16"
