A method of producing an insulation material, the method comprising fiberizing a wood material or another fiberizable material in the manufacturing process of pulp, performing washing and drying, said insulation material being refiberized later so as to provide it with a larger volume. The method is characterized in that an adhesive is added to the insulation material after the washing step but before the refiberization to be performed later so as to provide the insulation material with a larger volume.

L'invention concerne un procédé de production d'un matériau d'isolation, le procédé consistant à défibrer un matériau ligneux ou un autre matériau défibrable dans le processus de production de pâtes, à effectuer un lavage et un séchage, ledit matériau d'isolation étant refibré ultérieurement de manière à lui donner un plus gros volume. Le procédé est caractérisé en ce qu'on ajoute un adhésif au matériau d'isolation après l'étape de lavage mais avant le refibrage à exécuter ultérieurement, de manière à donner au matériau d'isolation un plus gros volume.
