L<\/span>a dalle est l’\u00e9l\u00e9ment cl\u00e9 de l’efficacit\u00e9 d’une maison passive. Celle-ci n’est pas coul\u00e9e \u00e0 m\u00eame le sol mais sur une couche isolante pr\u00e9alablement install\u00e9e comme support. Les nez de dalle sont particuli\u00e8rement sujets \u00e0 des erreurs de mise en oeuvre. Or ce sont eux qui assurent une continuit\u00e9 parfaite entre l’isolation de la dalle et l’isolation p\u00e9riph\u00e9rique des murs du sous-sol. A cette fin, des panneaux isolants sont int\u00e9gr\u00e9s lat\u00e9ralement dans le coffrage de la dalle mais il suffit qu’ils glissent au moment du coulage pour que des ponts thermiques apparaissent. JACKODUR Atlas, est un syst\u00e8me qui combine isolation et coffrage \u00e0 l’aide d’\u00e9l\u00e9ments en polystyr\u00e8ne extrud\u00e9 (XPS). Outre ses panneaux isolants grand format, le syst\u00e8me est constitu\u00e9 d’\u00e9l\u00e9ments lat\u00e9raux, et d’angle ainsi que des \u00e9l\u00e9ments de coffrage qui dessinent le plan masse du b\u00e2timent. Les \u00e9l\u00e9ments lat\u00e9raux et les pi\u00e8ces d’angle sont pourvus d’une rainure qui accueille les \u00e9l\u00e9ments de coffrage. Ainsi se constitue une liaison r\u00e9sistante \u00e0 la pression g\u00e9n\u00e9r\u00e9e par le b\u00e9ton coul\u00e9. L’\u00e9l\u00e9ment de coffrage fait en m\u00eame temps office d’isolant en nez de dalle. Ce coffrage perdu sera enseveli, excluant les erreurs de mise en oeuvre. JACKON Insulation est le seul fabricant \u00e0 produire des panneaux isolants pouvant atteindre 320 mm d’\u00e9paisseur. Solution brevet\u00e9e, cette \u00e9paisseur est obtenue en superposant plusieurs plaques de XPS, sur le principe du bois lamell\u00e9-coll\u00e9. Le multicouche poss\u00e8de les m\u00eames caract\u00e9ristiques techniques qu’un panneau extrud\u00e9 monocouche. Gr\u00e2ce \u00e0 ce proc\u00e9d\u00e9, il devient possible de r\u00e9pondre au niveau d’exigence passif avec une seule couche de panneau isolant.<\/p>\n","protected":false},"excerpt":{"rendered":"
