DensShield Tile Backer is a substrate that, when properly installed, resists the effects of water or moisture, making it excellent for protecting both tile installations and stud cavities. DensShield Tile Backer is composed of a water-resistant treated core that is covered front and back with figerglass mats. The coated fiberglass mats are permanently integrated with the core during manufacturing to help prevent delamination problems.
