R\u00e9sum\u00e9:<\/strong><\/p>\n

La r\u00e9novation thermique des constructions en pis\u00e9 pr\u00e9sente un d\u00e9fi dans l\u2019\u00e9volution actuelle vers des b\u00e2timents \u00e9conomes en \u00e9nergie. Pour pr\u00e9server le cachet du b\u00e2timent, une isolation int\u00e9rieure est appropri\u00e9e. Les risques hygrothermiques encourus doivent cependant \u00eatre minimis\u00e9s pour \u00e9viter les dommages. Pour ce faire, le pr\u00e9sent travail \u00e9tudie l’impact de diff\u00e9rents syst\u00e8mes d’isolation int\u00e9rieure sur les performances hygrothermiques des murs en pis\u00e9 (non enduits, au-dessus du soubassement, et en excluant les remont\u00e9es capillaires). Pour permettre cette recherche, on \u00e9tudie d’abord comment les propri\u00e9t\u00e9s hygriques des mat\u00e9riaux en pis\u00e9 peuvent \u00eatre d\u00e9termin\u00e9es de mani\u00e8re fiable et comment la r\u00e9ponse m\u00e9canique des murs en pis\u00e9 peut \u00eatre \u00e9labor\u00e9e. La m\u00e9thodologie comprend l’\u00e9tude de la litt\u00e9rature, la caract\u00e9risation exp\u00e9rimentale des mat\u00e9riaux, le d\u00e9veloppement d’indicateurs de performance th\u00e9oriques et la simulation num\u00e9rique des composants hygrothermiques. La technologie de pointe r\u00e9v\u00e8le un manque de propri\u00e9t\u00e9s hygriques d\u00e9termin\u00e9es. Ainsi, des mat\u00e9riaux en pis\u00e9 sont extraits des constructions existantes pour une caract\u00e9risation hygrique compl\u00e8te en laboratoire. Les r\u00e9sultats sont utilis\u00e9s comme entr\u00e9e dans l\u2019analyse de simulation num\u00e9rique hygrothermique du comportement des murs en pis\u00e9 dans des conditions climatiques r\u00e9alistes. De plus, l\u2019\u00e9tude de la technologie de pointe r\u00e9v\u00e8le un manque de crit\u00e8res de performances \u00e9labor\u00e9s et adapt\u00e9s aux applications en pis\u00e9, incluant sp\u00e9cifiquement les aspects m\u00e9caniques. Ces aspects m\u00e9caniques sont red\u00e9velopp\u00e9s et mis en oeuvre dans l’analyse des performances en mati\u00e8re de l’isolabilit\u00e9. Il s\u2019av\u00e8re que la pourriture du bois, la croissance de moisissures interstitielles, l\u2019humidit\u00e9 d\u00e9gouttante et \u00e9ventuellement la rupture par fracture et le flambement sont les principaux risques \u00e0 minimiser pour l\u2019isolation int\u00e9rieure des murs en pis\u00e9. Un syst\u00e8me d’isolation capillaire actif \u00e0 base de silicate de calcium assurant un s\u00e9chage optimal vers l’int\u00e9rieur de la pluie absorb\u00e9e pouss\u00e9e par le vent est le meilleur moyen de minimiser les risques. Par ailleurs, l’observation selon laquelle les r\u00e9ponses sur hygroscopiques jouent un r\u00f4le consid\u00e9rable dans les performances hygrothermiques des murs en pis\u00e9 d\u00e9montre l’importance de la caract\u00e9risation hygrique compl\u00e8te du mat\u00e9riau.
