  • Polyvalence d\u2019utilisation<\/strong> : convient pour murs, toitures, sols et combles.<\/li>\n
  • Confort de pose<\/strong> : non irritant, non allerg\u00e8ne, et facile \u00e0 d\u00e9couper.<\/li>\n
  • Durabilit\u00e9<\/strong> : fibres r\u00e9sistantes et imputrescibles, sans tassement dans le temps.<\/li>\n
  • R\u00e9gulation hygrothermique<\/strong> : assure un confort optimal dans les espaces isol\u00e9s.<\/li>\n
  • Fabrication fran\u00e7aise<\/strong> : \u00e9labor\u00e9 dans une d\u00e9marche valorisant les fili\u00e8res locales.<\/li>\n<\/ul>\n

    Techniques de pose adapt\u00e9es<\/strong><\/h3>\n
      \n
    1. Combles am\u00e9nag\u00e9s<\/strong> :
      \nInstallez l\u2019isolant entre et sous les chevrons pour une performance thermique optimale.<\/li>\n
    2. Combles perdus<\/strong> :
      \nD\u00e9posez les panneaux en couches crois\u00e9es sur le sol pour couvrir efficacement les surfaces.<\/li>\n
    3. Murs int\u00e9rieurs<\/strong> :
      \nPosez les panneaux entre des montants pour un doublage performant.<\/li>\n
    4. Plafonds et planchers<\/strong> :
      \nPlacez l\u2019isolant entre solives ou en double couche pour renforcer l\u2019efficacit\u00e9 thermique.<\/li>\n
    5. Isolation thermique ext\u00e9rieure (ITE)<\/strong> :
      \nUtilisation possible sous conditions sp\u00e9cifiques (hors Avis Technique).<\/li>\n<\/ol>\n
