Tile for covering a building wall, which is extended along a main lying plane, is made at least of a ceramic material and comprises: - a visible portion, which is extended between an external face substantially parallel to said main lying plane and intended, during use, to be visible and an internal face substantially parallel to said main lying plane and spaced with respect to the internal face by a first thickness orthogonal to said main lying plane; - a fixing portion extended from the internal face of said visible portion and comprising a plurality of projections which are extended, starting from the internal face of said visible portion, transverse to said main lying plane for a second thickness; wherein the height of the plurality of projections of said fixing portion is greater than or equal to half the first thickness of said visible portion; wherein each projection of said plurality of projections delimits, with at least one adjacent said projection thereof, a containment volume susceptible of containing at least one dose of filling material different from the ceramic material of said tile; wherein each projection is extended transverse to said main lying plane between a base at the internal face of said visible portion provided with a first width, parallel to said main lying plane, and an end opposite said base provided with a second width; wherein said fixing portion comprises a plurality of bottom sections, wherein each said bottom section is placed to connect between the bases of contiguous projections of said plurality of projections and delimits, together with said contiguous projections, said containment volume; wherein each said projection comprises a lateral wall which joins said base to the corresponding said end, and said lateral wall externally delimits said containment volume in order to house the corresponding dose of filling material; said tile being characterized in that said first width is comprised between 2mm and 40mm, and said second width is comprised between 0.4mm and 30mm; and in that each bottom section of said fixing portion is concave with curvature radius comprised between 15mm and 50mm; wherein said bottom section has curved and rounded shape and is connected to the lateral walls of the corresponding containment volume by means of respective rounded connector sections; wherein each projection is extended with tapered form from said base towards said end, with the first width of said base greater than the second width of said end. - a visible portion, which is extended between an external face substantially parallel to said main lying plane and intended, during use, to be visible and an internal face substantially parallel to said main lying plane and spaced with respect to the internal face by a first thickness orthogonal to said main lying plane; - a fixing portion extended from the internal face of said visible portion and comprising a plurality of projections which are extended, starting from the internal face of said visible portion, transverse to said main lying plane for a second thickness; wherein the height of the plurality of projections of said fixing portion is greater than or equal to half the first thickness of said visible portion; wherein each projection of said plurality of projections delimits, with at least one adjacent said projection thereof, a containment volume susceptible of containing at least one dose of filling material different from the ceramic material of said tile; wherein each projection is extended transverse to said main lying plane between a base at the internal face of said visible portion provided with a first width, parallel to said main lying plane, and an end opposite said base provided with a second width; wherein said fixing portion comprises a plurality of bottom sections, wherein each said bottom section is placed to connect between the bases of contiguous projections of said plurality of projections and delimits, together with said contiguous projections, said containment volume; wherein each said projection comprises a lateral wall which joins said base to the corresponding said end, and said lateral wall externally delimits said containment volume in order to house the corresponding dose of filling material; said tile being characterized in that said first width is comprised between 2mm and 40mm, and said second width is comprised between 0.4mm and 30mm; and in that each bottom section of said fixing portion is concave with curvature radius comprised between 15mm and 50mm; wherein said bottom section has curved and rounded shape and is connected to the lateral walls of the corresponding containment volume by means of respective rounded connector sections; wherein each projection is extended with tapered form from said base towards said end, with the first width of said base greater than the second width of said end.
