Polystyrene foam sandwiched between quality papers creates a surface that stays flat under pressure and cuts without crushing. Fome-Cor boards handle mounting, display construction, and temporary signage with the kind of structural integrity that prevents sagging corners and warped edges. The ultra-smooth facing accepts adhesives evenly, eliminating bubbles and wrinkles that compromise professional presentation work.

White Fome-Cor features clay-coated papers on both sides with a white core, clean edges for general mounting, die-cutting, and embossing projects. Black-centered boards pair uncoated black papers with a crisp black core that eliminates distracting white lines when trimming mounted photographs or gallery prints. Acid-free versions use high alpha-cellulose virgin pulp papers, lignin-free throughout, meeting conservation standards for archival mounting applications.

Lightweight rigidity simplifies handling large format work. Mount a 30×40-inch print without wrestling heavy substrates, build display structures that stay square during assembly, create dimensional signage that holds its shape. The foam core compresses slightly under blade pressure for clean cuts with standard utility knives, no specialized equipment required. Screen printers appreciate the smooth, stable surface for registration and ink coverage.
