Façade insulating system

An insulation panel for a façade insulating system of a building, the insulation panel being made of a thermal insulation material and wherein the insulation panel comprises:

• a first surface configured to face a wall of the building,
• a second surface opposite the first surface, the second surface being configured to face an outer panel,
• protrusions distributed over the second surface, the protrusions having a cylindrical shape or a truncated cone shape and being a solid body of thermal insulation material, wherein the protrusions are configured to abut the outer panel, such that air channels are formed between the second surface of the insulation panel and the outer panel when the protrusions abut against the outer panel, and
• wherein the insulation panel is configured to be connected to the wall of the building through a plurality of fastening devices,
• wherein each of the plurality of fastening devices comprises a distancing section,
• wherein the distancing section comprises two bracket sections,
• wherein a first bracket section of the two bracket sections defines a first contact surface that abuts against the second surface of the insulation panel;
• wherein a second bracket section of the two bracket sections defines a second contact surface that abuts against an inner surface of the outer panel, thereby determining a distance equal to a height of the protrusions between the second surface of the insulation panel and the inner surface of the outer panel.
