Overview
What is Ultra Board?
Ultra Board is a rigid, high-performance display board that pairs a lightweight polystyrene foam core with durable, bright-white plastic facers. That plastic facing — rather than paper or wood-fiber — gives it a smooth, brilliant-white surface for high-resolution printing and strong resistance to warping.
It holds its shape and finish over time, making it a top choice for premium, long-term indoor signage: POP displays, trade-show panels, and wall-mounted graphics. Like all foam-core boards it’s an indoor-only material, but among them it’s one of the most rigid and print-ready options.
