Acoustic – decorative boards of mineralised wood wool
The wood wool board DRVOLIT ACOUSTIC is made of mineralised wood-wool with a specific fine structure that together with cement binder and additives makes up a compact unit. By the process of mineralization, the fire resistance of wood wool increases greatly. Due to its porous internal structure and the shape of the surface it is an excellent insulator for noise protection systems. During the manufacturing process the appearance of the surface is accurately controlled, because the boards stay visible after installation.
