Commonly known as foam board or foam core, this rigid sign material consists of a polystyrene foam center with white clay-coated paper applied to either side. Foam board panels are used for affordable and lightweight temporary signage, often at events and tradeshows, and can be customized with different shapes, colors, and graphics.
The extruded polystyrene foam used in these display boards is one of the most common plastics in manufacturing, produced at competitive costs by several manufacturers. Consisting of approximately 95% air, this material is lightweight. The final weight depends on the thickness, with options including:
Signs made from foam board are often rectangular, measuring:
They can also be trimmed into custom sizes or non-rectangular shapes.
Paper-faced foam board is available in several standard colors beyond white, including black, red, green, blue, and yellow. White is typically used to avoid dull colors caused by printing over a colored background. For foam board printing, graphics are digitally printed with UV inks in a four-color process. These inks are applied directly to the untextured surface of the foam board and cured with ultraviolet lights. The coated paper and inks allow for photo-realistic designs to be printed onto foam core. Graphics can be printed on one or both sides of the sign and printed edge to edge so that no border shows on the sign.
Foam board is also used in photograph and picture mounting, providing a rigid backing for photos. However, since the paper is not acid-free, it can deteriorate the image over many years.
Foam board is lightweight and cost-effective but not waterproof, making it unsuitable for outdoor use unless sheltered and for extended periods. It should be handled gently to avoid damage. Display options include:
Foam board signs can also have polystyrene foam clad with layers of polystyrene or wood fiber veneer instead of paper, such as with materials like Ultraboard or gatorboard. The polystyrene provides a solid plastic surface with a smooth or textured finish, offering additional durability. However, this material is not flexible, and bending will cause the polystyrene layer to snap. Rough handling can also cause dents and crushed corners. When used and stored properly, foam board signs can last indoors for several years. Smudges and dust can be removed with a dry or slightly damp cloth.
