d\u00e9tectable en hiver par temps de neige. La neige accumul\u00e9e<\/p>\n

sur les toits, fondra plus vite, des qu’une habitation<\/p>\n

pr\u00e9sentera un d\u00e9faut d’isolation au niveau de sa toiture voir<\/p>\n

exemple de la photo ci-contre.<\/p>\n

\"\"<\/p>\n

3<\/strong>– Pour am\u00e9liorer le confort thermique d’une habitation, nousutilisons des isolants thermique qui permettent de r\u00e9duire laquantit\u00e9 de chaleur transmise avec l’ext\u00e9rieure. Plusieurstypes de mat\u00e9riaux isolants existent:<\/p>\n

a-<\/strong>isolant min\u00e9ral (laine de verre, laine de roche ,etc.),<\/p>\n

b-<\/strong> isolant naturels:<\/p>\n

. isolant v\u00e9g\u00e9tal (ex: li\u00e8ge, fibre de lin, ouate de cellulose, chanvre, fibre de bois,<\/p>\n

paille, toiture v\u00e9g\u00e9talis\u00e9e, etc.<\/p>\n

.isolant animal (laine de mouton, plus de canard, etc.),<\/p>\n

c<\/strong>– Les isolants synth\u00e9tiques (polystyr\u00e8ne expans\u00e9, polyur\u00e9thane, etc.)<\/p>\n

d<\/strong>– Les isolants nouvelle g\u00e9n\u00e9ration (brique, monomur, b\u00e9ton cellulaire, panneaux isolants+sous vide PIV, etc…).<\/p>\n

e- Les isolants mince appel\u00e9s aussi \u00ab\u00a0isolants r\u00e9flecteurs\u00a0\u00bb, \u00ab\u00a0multicouches\u00a0\u00bb. Ils sont assembl\u00e9s d’une ou plusieurs couches d’aluminium ou film plastique alumin\u00e9, l’isolant mince comprend diff\u00e9rentes couches de nature diverses: mousse souple, poly\u00e9thyl\u00e8ne \u00e0 bulles, feutre d’origine animale, v\u00e9g\u00e9tale ou synth\u00e8se. Ce sont des isolants de faible \u00e9paisseur.<\/p>\n

4<\/strong>-On am\u00e9liore l’isolation thermique d’un mat\u00e9riau en augmentant son \u00e9paisseur. pour une efficacit\u00e9 optimale, toutes les parois doivent \u00eatre isol\u00e9es<\/strong>. pour une habitation, on isole les murs ext\u00e9rieurs, le plancher sur vide sanitaire et le plafond sous les combles (toiture).<\/p>\n

5<\/strong>– La performance thermique d’un mat\u00e9riau isolant s’appelle la r\u00e9sistance thermique<\/strong> R.<\/p>\n

 <\/p>\n

plus\u00a0R\u00a0<\/strong>est grand et plus le mat\u00e9riau est isolant.<\/p>\n

R<\/strong> d\u00e9pend de deux param\u00e8tres: en fonction de la conductivit\u00e9 thermique\u00a0lambda\u00a0<\/strong>propre \u00e0 chaque mat\u00e9riaux et en fonction de son \u00e9paisseur\u00a0e<\/strong>.<\/p>\n
