Malgr\u00e9 un march\u00e9 de la construction morose, le chiffre d’affaires du march\u00e9 des mat\u00e9riaux biosourc\u00e9s a atteint 97,7 millions d’euros en 2025, soit 6,7 % de plus qu’en 2023 et ses 91,6 millions d’euros de CA.<\/strong><\/p>\n

En volume, la progression est notable : 32,7 millions de m\u00b2 ont \u00e9t\u00e9 mis en \u0153uvre l’ann\u00e9e derni\u00e8re, contre 28,2 millions de m\u00b2 en 2023, soit +16 %. Les isolants biosourc\u00e9s repr\u00e9sentent quant \u00e0 eux 8,2 % du march\u00e9, contre 7,5 % en 2024 et 6,4 % en 2023, et p\u00e8sent pour 11 % du march\u00e9 de l’isolation. La p\u00e9n\u00e9tration des isolants biosourc\u00e9s est constante depuis dix ans, avec +126 % depuis 2016.<\/p>\n

L’isolant semi-rigide repr\u00e9sente 17,6 millions de m\u00b2 mis en \u0153uvre en 2025 (54 % des volumes), contre 13,3 millions de m\u00b2 en 2023 (47 %). Il est principalement utilis\u00e9 en isolation int\u00e9rieure des murs, cloisons et rampants. Viennent ensuite les isolants en vrac avec 10,7 millions de m\u00b2, soit 33 % de part de march\u00e9, contre 12,5 millions de m\u00b2 (44 %) en 2023. Une baisse que l’AICB explique par des volumes de vrac stables, \u00ab tandis que les autres familles de produits gagnent du terrain sur de nouveaux usages. \u00bb<\/em> L’isolant en vrac reste la solution biosourc\u00e9e la plus employ\u00e9e pour l’isolation des combles perdus.\u00a0\"\"<\/p>\n

Le b\u00e9ton biosourc\u00e9 en forte progression<\/h2>\n

Principalement utilis\u00e9s pour l’ITE, les isolants rigides progressent \u00e9galement, avec des volumes qui ont presque doubl\u00e9 en deux ans. Ils repr\u00e9sentent en effet 3,5 millions de m\u00b2 (11 %) du march\u00e9, contre 1,8 million de m\u00b2 (6 %) en 2023. Port\u00e9s par la construction hors-site et la fabrication de murs ext\u00e9rieurs, les b\u00e9tons biosourc\u00e9s enregistrent une progression de 50 % en volume, pour atteindre 3 % de part de march\u00e9.<\/p>\n

Pour cette \u00e9dition du barom\u00e8tre, l’AICB a publi\u00e9 une cartographie r\u00e9gionale des volumes mis en \u0153uvre, document qui vise \u00e0 refl\u00e9ter les dynamiques territoriales \u00e0 l’\u0153uvre. Ainsi, le podium est occup\u00e9 par l’Auvergne-Rh\u00f4ne-Alpes (20 % des volumes nationaux), la Bretagne (12,7 %) et la Nouvelle-Aquitaine (10,8 %). Des chiffres qui s’expliquent notamment par l’int\u00e9gration \u00e9lev\u00e9e de mat\u00e9riaux biosourc\u00e9s dans le neuf, ainsi que par la pr\u00e9sence de fili\u00e8res et de ressources locales.<\/p>\n
