Support plate for installing tile
A support for installing facing materials such as ceramic tiles on a substrate, such as, floors, walls and ceilings. The support plate has a plurality of spaced apart raised portions and recesses in the plate material, and a plurality of openings extending through the top surface and bottom surface of the plate material. The openings exposing a mat layer attached to the bottom of the support plate. Support plates of the invention are used for tile installations between a substrate and tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the openings forming a continuous bond between the mortar, openings and mat layer to provide a strong bond between the support plate, mortar and the tiles.
