How does DensShield® tile backer compare with cement board?
DensShield Tile Backer has a built-in moisture barrier and therefore does not require a secondary moisture barrier. Cement board does not have a built-in moisture barrier and may require a secondary moisture barrier. In addition, DensShield has a considerable weight advantage over cement backers. It’s 30% lighter than the leading cement board brands (1/2″ comparison). That makes DensShield easier to handle on the job site and faster to install. A study conducted by the National Association of Home Builders (NAHB) Research Institute showed that DensShield is 46 percent faster to install than cement board.
