You can use the Av_slim profile in the exposed or concealed configuration.
In the exposed configuration, Av_slim internally welcomes the cladding plate, leaving 4 mm of aluminum visible. In this configuration, a carving (kerf) in the plates is not necessary.
In the concealed configuration, the plate must have a carving (kerf), 2 mm wide, so that the Av_slim profile can disappear inside.
Another use of the Av_slim profile provides the possibility of using thick stone plates with easy installation.
