SignFoam 4 - HDU (48" x 120" x 1.5") 15 lb.

Sign Foam4 is offered in the 15 and 18 pound densities. Sign Foam provides a superb substrate for dimensional sign making, environmental graphics, 3-D displays and model making. It is virtually indestructible, so it offers an unlimited lifespan in any application - inside or out. Sign Foam is lightweight, yet remarkably strong and stable over time. It is impermeable by water and moisture, and unaffected by high-salt environments. And, the material is formulated to withstand temperatures from -30^oF to 220^oF. So it holds up under extreme conditions and in severe weather. Sign Foam clearly outperforms wood and ordinary HDUs.
