to properly retain individual thin brick tiles the backing member has a generally uniform cross section throughout its entire length providing channels which allow the thin brick tiles to lay uniformly across each row the channels are defined by retaining bars which hold the thin brick tiles in place the retaining bars include mortar lock notches which are adapted to provide a dovetail connection between the mortar and the backing board as well as a path for moisture and water to escape from the brick panel assembly application_number US 19961594 A description referring now to fig1 3 an inventive thin brick panel assembly 20 includes a backing member 22 support clips 24 and individual thin brick tiles 26 mortar 28 is applied along the area between the thin brick tiles 26 to form a brick facing 30 support clips 24 are used during assembly to initially anchor the backing member 22 and ultimately the completed brick facing 30 to the underlying building structure 32 the backing member 22 is formed from a single sheet of material backing member 22 includes an insulate base 34 and generally parallel holding guides 36 which extend outwardly from and are integral to the insulated base 34 the holding guides 36 are spaced to define channels 38 one side 39 of the holding guide 36 is angled to form a knife edge 40 which extends into adjacent channel 38 knife edge 40 retains thin brick tiles 26 within channel 38 and also allows accommodation of tolerances in the size of thin brick tiles 26 another side 41.
