Custom Building Products If traditional fiber-cement backerboard went on a diet, it might become EasyBoard. One sheet of fiber-cement backerboard can weigh as much as 45 pounds; a sheet of EasyBoard weighs 6 pounds, making it easier to transport and carry. The product is manufactured using a polyiso foam instead of concrete or gypsum, yet still offers dimensional stability and resists mold and water, the firm says. The sheets cut with a utility knife, creating no dust. "There was none of the usual cement dust, so cleanup was a breeze," said James Eaton of Atlanta-based Eaton Tile in a written testimonial. 800.282.8786.
