Comprendre la conductivit\u00e9 thermique<\/b><\/p>\n

Chaque mat\u00e9riau conduit la chaleur plus ou moins efficacement.<\/p>\n

    \n
  • Conductivit\u00e9 (\u03bb)<\/b>\u00a0: plus elle est faible, plus le mat\u00e9riau est isolant.<\/li>\n
  • R\u00e9sistance thermique (R)<\/b>\u00a0= \u00e9paisseur \/ \u03bb.
    Une paroi performante pr\u00e9sente un\u00a0U faible<\/b>\u00a0(valeur inverse de R).<\/li>\n<\/ul>\n

    Les ponts thermiques (liaisons murs\/dalles, ch\u00e2ssis, jonctions toiture) entra\u00eenent des pertes importantes.<\/p>\n

    Reconnaissance pratique des mat\u00e9riaux<\/b><\/p>\n

    Lors d\u2019un certificat PEB, le certificateur identifie les mat\u00e9riaux \u00e0 l\u2019aide de :<\/p>\n

      \n
    • Photographies et inspection visuelle ;<\/li>\n
    • Plans ou fiches techniques ;<\/li>\n
    • Documents probants (factures, \u00e9tiquettes, rapports d\u2019isolation).<\/li>\n<\/ul>\n

      Impact sur la note PEB<\/b><\/p>\n

      Un mur isol\u00e9 avec 12 cm de PUR au lieu d\u2019aucune isolation peut faire\u00a0gagner deux classes \u00e9nerg\u00e9tiques<\/b>.<\/p>\n
