Abstract

L'invention concerne un corps façonné (1) s'utilisant dans l'industrie du bâtiment, qui s'obtient par le fait qu'au moins une section (2) d'une plaque de laine minérale (7) est pourvue d'un revêtement (8, 9) en résine synthétique, qui pénètre au moins en partie dans la plaque de laine minérale (7). Afin d'obtenir une surface de haute qualité, le revêtement peut comporter une charge telle que du ciment, qui confère par conséquent à ladite surface une bonne aptitude au façonnage. Le corps façonné peut également comprendre des éléments de renforcement, tels que des armatures en métal, qui augmentent sa capacité portante. Ce procédé permet d'obtenir des corps façonnés à haut degré d'isolation thermique et d'aspect agréable pouvant servir, par exemple, d'appuis de fenêtres ou d'éléments de bardage.
