25. Soundproof

Special Ceramic Beads in GAINA reflect sound and suppress vibration.

GAINA coating(membrane) is made up of multi-layered hollow ceramic beads containing air inside.

The structure of the ceramic beads reflects the sound and the air within absorbs the vibration.

Thus GAINA has a soundproofing effect. When the sound enters the film, the multi-layer ceramic hollow beads reduce the sound by suppressing the vibration.
