Foam boards having an anistropy such that the cells are compressed in a direction of the board thickness, the boards having a density of from 15 to 45 kg/m3 and the ratio between the long and short axes in the compressed cells being from 1.2 to 1.6, have improved insulation properties.
a présente invention vise des panneaux de mousse ayant une anisotropie telle que les cellules sont comprimées dans le sens de l'épaisseur des panneaux. Les panneaux ayant une masse volumique comprise entre 15 kg/m3 et 45 kg/m3 et le rapport entre le grand axe et le petit axe dans les cellules comprimées allant de 1,2 à 1,6, ils ont des propriétés isolantes améliorées.
