Abstract

L'élément, de fabrication aisée, assurant une isolation contre le froid et la chaleur et destiné en particulier aux coffrages à béton, échafaudages et clôtures, comporte une structure de stabilisation (1) indéformable, laquelle est noyé dans une couche d'enrobage (2) viscoplastique à laquelle il est lié par liaison de force au moyen d'un adhésif. La couche d'enrobage est constituée d'un mélange de granulés de caoutchouc différents les uns des autres et est dotée d'un revêtement de protection de surface (5) élastique et dépourvu de porosités. Le mélange de la couche d'enrobage peut se composer de fins granulés de caoutchouc, de granulés de caoutchouc vulcanisés et d'un élastomère.
