4mm Foam Board

Create lightweight, professional indoor signage with custom 4mm foam board signs. Foam board combines a smooth printable surface with a lightweight foam core, making it an excellent choice for displays that need to look polished without the weight of a rigid outdoor sign material.

Printed in vibrant full-color CMYK on one or both sides, foam board works well for retail displays, presentations, trade shows, conferences, menu boards, directional signage, event graphics, photo displays, point-of-purchase signage, and temporary indoor promotions.

With sizes ranging from compact 6" × 24" signs to large 48" × 48" displays, you can create everything from tabletop graphics to larger presentation boards. Each piece is cut to size, and optional grommets are available when your display requires hanging installation.

Because foam board is designed primarily for indoor use, it is best suited for controlled environments where the sign will not be exposed to rain, high humidity, or prolonged outdoor conditions.
