Abstract

L'invention concerne une enveloppe pour la galerie chaude d'un espace de calcul, séparant l'espace situé au-dessus de la galerie chaude et s'étendant de l'arête supérieure des armoires, des portes ou de la paroi arrière d'une galerie chaude, jusqu'à une structure de plafond, notamment un faux-plafond. L'invention vise à mettre en oeuvre une enveloppe simple pour des armoires et des faux-plafonds de hauteurs variables, dont le montage peut être réalisé rapidement par une seule personne. A cet effet, l'enveloppe comporte des profilés verticaux et des tôles de séparation en plusieurs parties, notamment en deux parties, conçus de façon à pouvoir être réglés en hauteur et extraits de manière télescopique, et formant un parement quasiment exempt de joints.
