Isolation phonique naturellement<\/h2>\n

M\u00eame s’il est performant en isolation thermique, son utilisation principale reste l’isolation acoustique (murs mitoyens, cloisons,…)<\/p>\n

Sa composition fait de lui un isolant naturel, \u00e9cologique et sain (pas d’\u00e9mission de COV).<\/p>\n

Performances acoustiques valid\u00e9es<\/h3>\n

L\u2019association de la ouate de cellulose haute densit\u00e9 aux fibres de chanvre, procure \u00e0 Biofib\u2019ouate d\u2019excellentes performances d\u2019isolation phonique, pour un meilleur confort acoustique.<\/p>\n

Les niveaux d\u2019affaiblissement acoustiques mesur\u00e9s et certifi\u00e9s (essais FCBA) sur des parois types sont nettement sup\u00e9rieurs aux exigences r\u00e9glementaires.<\/p>\n<\/div>\n
