HDU is an ideal alternate to wood. HDU is a rigid foam board that is available in various densities. Unlike EPS, it is a much higher density and contains less air. Unlike wood, HDU will not split, warp or rot. Since HDU is a “closed cell” material, water cannot penetrate it even in its raw state, which makes it ideal for exterior applications even in the harshest climates.
HDU can be used for Post and Panel signs, directional post mount signs, monument sign faces, block letters, plaques, medallions, logos and any application where smooth finishes and fine detail are required. HDU signs can be routed with raised copy and borders and three dimensional detail, engraved with V-Groove inset elements or smooth sanded with direct digital prints. Premium wood grain routing is also available.
