The invention relates to a coating applicable to a building surface for producing a thermally insulating coating, this coating comprising water, binder (a) mineral and / or organic hydraulic, optionally a structuring charge (c) and optionally adjuvants (d), characterized in that it further comprises an insulating filler (b) comprising a powder or a granulate of at least one hydrophobic silica xerogel obtained by treating a silica organogel with a hydrophobic agent in the presence of acid and in a solvent; separating the hydrophobic organogel obtained; and removing the solvent from the organogel by evaporation. The preparation of such an application coating by spraying on a building surface and the coating thus obtained constitute other objects of the present invention. |
