The present invention relates to a process for the production of a composite element. The process includes (i) provision of an outer layer with an uncoated surface and a coated surface coated at least partially with a composition (B) including at least one inorganic material, (ii) treatment of the uncoated surface of the outer layer and (iii) application, to the treated surface of the outer layer, of a composition (Z2) suitable for the production of a polyurethane foam and/or polyisocyanurate foam. The present invention further relates to a composite element obtainable or obtained by a process of the invention, and also to the use of a composite element obtainable or obtained by a process of the invention or of a composite element of the invention as insulation material or in the construction of façades.
