TEST DATA
KERDI, KERDI-DS, DITRA, and DITRA-XL have been independently tested and found to meet or exceed the requirements of the American
National Standard Specifications for Load Bearing, Bonded, Waterproof Membranes for Thin-set Ceramic Tile and Dimension Stone
Installation A118.10. Data for KERDI and KERDI-DS are presented in the table below.
KERDI, KERDI-DS, and KERDI-BOARD have also been independently tested to determine the water vapor permeance of the products.
Please see further discussion on the importance of water vapor permeance on page 39.
