Abstract

Isolateur caractérisé en ce qu'il est largement exempt de condensation d'humidité. Au moins la surface de l'isolateur 1 est constituée en un matériau isolant de faible capacité calorifique et/ou en un matériau isolant de faible conductibilité thermique. Les matériaux utilisés sont de préférence les matières thermo-durcissables poreuses, par exemple la résine époxyde ou la réside silicone. Ces isolateurs 1 peuvent être réalisés sous la forme de corps en mousse présentant une répartition de densité non homogène, le noyau 3 en mousse se transformant continuellement en une croute dense 2 constituée par la même matière synthétique.Insulator characterized in that it is largely free from moisture condensation. At least the surface of the insulator 1 is made of an insulating material of low heat capacity and / or of an insulating material of low thermal conductivity. The materials used are preferably the porous thermosetting materials, for example epoxy resin or silicone resin. These insulators 1 can be produced in the form of a foam body having a non-homogeneous density distribution, the foam core 3 continuously transforming into a dense crust 2 made up of the same synthetic material.
