Custom Foamcore 3/16” Signs

Our custom foamcore signs are made using polystyrene foam sandwiched between either paper, plastic, or a clay paper surface.

Common color combinations include a white core with white faces, black core with white faces, and black core with black faces. The custom Foamcore signs are typically used indoors for trade shows, directional and informational signage, temporary signs of all kinds, individual letters, easel displays, and interior displays.

Foamcore is easily cut or routed and can be painted with certain types of paint and is a great substrate for the mounting of digital prints including photographs and graphics for wall displays. Paper-faced Foamcore is very fragile and easily bent, so may not be suitable for traveling displays or for use in public areas.
