The thermal insulation plate for building purposes has a bottom surface (6) with alternating protrusions (4) and depressions (3) which are provided with a layer (7) capable of absorbing water and/or water vapor. The thermal insulation plate for building purposes has a bottom surface (6) with alternating protrusions (4) and depressions (3) which are provided with a layer (7) capable of absorbing water and/or water vapor. Alternatively the entire bottom surface of the thermal insulation plate consists of the same material as the layer (7). In this case a vapor diffusion barrier or impedance layer can be located between the thermal insulation layer (2) and the material forming the protrusions and depressions (4, 3).
