1. A honeycomb decoupling sheet, for installation of facing materials on a substrate with a first bonding layer between the substrate and the sheet, and a second bonding layer between the sheet and the facing material, wherein the sheet is impermeable and comprises a plurality of reliefs and concavities forming substantially parallel upper and lower planes of the sheet, and a layer of permeable material attached to the lower plane and suitable for contact with the first layer, comprising:
a tessellated shape from a repeating regular hexagon geometrical unit, wherein this unit comprises:
a first prominence located in the center of the unit, which forms a first air chamber inside the unit;
a first concavity arranged around the first prominence such that the first air chamber forms a closed volume of air between the sheet and the layer of permeable material adhering to the bottom plane;
six second prominences, where each is located at a vertex of the unit and corresponds to one-third of the first prominence, and, one-third first concavity arranged around each second prominence, such that the union of three units permits the formation of a complete first prominence and first concavity at each joint of the vertices, and;
six second concavities equidistant from each other arranged with a radial distribution with respect to the center of the unit such that they determine a circular array between the first concavity and the thirds of the first concavity;
wherein the plurality of reliefs configures a lattice around the first and second concavities forming a second continuous air chamber incommunicable with each first chamber and, wherein the first and second concavities are incommunicable with each other and are suitable for containing the material of the second layer.
