DRVOLIT AKUSTIK DA A2

DRVOLIT AKUSTIK DA A2

Mineralised wood wool decorative acoustic boards

DRVOLIT AKUSTIK DA A2 is made of mineralised wood wool with a very fine structure bonded together with cementitious binders and additives to form a compact unit. The mineralisation process greatly increases the fire resistance of wood wool. Its porous internal structure and surface design make it an excellent insulator in noise protection systems. Surface appearance is also carefully controlled during the manufacturing process, as the boards remain visible after installation.
