Lignostone® - le bois comprimé à la résine synthétique provenant directement de l'inventeur. Composé de placages en hêtre commun (Fagus sylvatica), baigné des résines synthétiques durcissables sous pression et sous l'effet de la chaleur. Plus de 100 ans d'expérience. Pour des propriétés mécaniques et isolantes exceptionnelles et scientifiquement prouvées.
La qualité adaptée à chaque application spécifique est déterminée par les codes suivants :
Niveau de compression
H = 1,30 à 1,40 g/cm³
Disposition des couches I = couches longitudinales
II = couches croisées
X = couches tangentielles
Épaisseur de couche 1 = Épaisseur de feuille de placage < 2 mm
2 = Épaisseur de feuille de placage ≥ 2 mm
Type de résine sans code = types mécaniques
E3 = types électriques
