What is the strength of denshield tile?
1⁄49 (6.4 mm) DensShield Tile Backer panels have a compressive strength of approximately 1200-1500 lbs psi, and 1⁄29 (12.7 mm) DensShield Tile Backer has a compressive strength of between 450 and 600 lbs psi. That means that it would typically take a load of 450 to 600 lbs psi to start to crush 1⁄29 (12.7 mm) DensShield Tile Backer.
