HDU (High Density Urethane) is an ideal alternative to wood. HDU is a rigid foam board that is available in various densities. 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. #betterfromthetop #signs #signshop #customsigns #customsignshop #hdusigns #entrancesigns #hangingsigns #businesssigns #exteriorsigns #atlsigns #atlantasigns
