A combustion membrane (14) for a gas burner (2) comprises a fabric (21) having two opposite fabric surfaces (19, 20) which form a combustion surface (19) exposed on the outer side (17) and an inner surface (20) facing an inner side (18), respectively, wherein the fabric (21) forms an interlacement of metal threads (22) comprising warp threads and weft threads transverse with respect to the warp threads, wherein both fabric surfaces (19, 20) form high-relief ribs (23) alternating with low-relief sags (24), and the ribs (23) comprise: weft ribs (25) formed by weft threads and extending in the weft direction (26) arranged in weft rib sequences (2) aligned along weft directions (26) substantially straight and parallel to one another, and warp ribs (27) formed by warp threads and extending in the warp direction (28) and arranged in zigzag warp rib sequences (27), wherein all the warp threads participate in the formation of said warp ribs (27) in an alternating and repetitive manner along the extension thereof in the warp direction (28).

A combustion membrane (14) for a gas burner (2) comprises a fabric (21) having two opposite fabric surfaces (19, 20) which form a combustion surface (19) exposed on the outer side (17) and an inner surface (20) facing an inner side (18), respectively, wherein the fabric (21) forms an interlacement of metal threads (22) comprising warp threads and weft threads transverse with respect to the warp threads, wherein: both fabric surfaces (19, 20) form high-relief ribs (23) formed by a main float thread (25), respectively, extending straddling exactly three underlying transverse threads, and wherein a side thread bridge (25), extending straddling exactly one underlying transverse thread, is formed on both longitudinal sides of each main float thread (25), so that the main float thread (25) and the two side thread bridges (25) delimit a cross thread configuration (25) formed by mutually parallel threads.

A combustion membrane (14) for a gas burner (2) comprises a fabric or mesh (21) of interlaced metal threads (22), having two opposite interlacing surfaces (19, 20) which form a combustion surface (19) and an inner surface (20) of the fabric/mesh (21), respectively, wherein the metal threads (22) are formed by twisted metal fibers (22) to form a yarn and: the individual metal fibers (22) are shorter than the yarn (22) formed therefrom, and free ends (22) of the metal fibers (22) protrude divergently from the yarn (22) along its longitudinal extension and make the yarn (22) hairy, and the metal thread (22) is a yarn (22) of mass per length in the range from 0.8 g/m to 1.4 g/m.
