FIBER CEMENT

摘要

The same ingredients used to make cement backerboard are present in fiber-cement backerboard; the difference is that fiber cement also includes cellulose fiber. The main brands of fiber-cement backerboard are HardieBacker and CertainTeed FiberCement BackerBoard. HardieBacker comes in two thicknesses: 1/4 in. for floors or countertops and 0.42 in. for walls. At about 7/16 in., 0.42-in.-thick HardieBacker is a little thinner than 1/2-in. cement backerboard, which is one reason why it is lighter (2.6 Ib. per sq. ft.).
