The free space provides a route for excess moisture and vapor to escape from the substrate that could otherwise cause damage to the tile layer above.
The minimum height that my new dishwasher can be adjusted to is 33 3 4 and the cabinet height is 34 1 2.
Thus ditra effectively manages moisture beneath the tile.
Nominal 1 4 5 5 mm thickness minimizes tile assembly thickness and reduces transitions to lower surface coverings.
