Isophon Bars

Applications and typologies
Often used in combination with Isophon Light ™ panels, Isophon bars serve to reduce and dampen vibrations and noise, resulting from engine propulsion, aboard the most prestigious boats.
The bars are available in three different typologies to meet the needs of vibration reduction both on the floor and on the wall, thus guaranteeing the highest acoustic comfort inside the rooms.
Isophon Floor™
Ideal to make anti-vibration leveling floors for medium and large boats. Normally, the bars are laid down in grid pattern onto the floor, at 50 cm intervals, and to achieve the best soundproofing performance, they are covered with Isophon Light™. Excellent to isolate underfloor, decks and floors in touch with or very close to noise sources.
Isophon Floor Single - Side™
The single-side version offers the same features as the Isophon Floor™ bar, but only one plywood face. Therefore, rubber is glued directly onto the raw surface of the underfloor (fiberglass, aluminum, steel). This solution is preferable when a thinner product has to be processed or when the surface is uneven.
Isophon Wall™
The Isophon Wall™ variant is designed to be applied vertically onto walls and bulkheads next to the noise source. Combined with the Isophon Light™ panel, it is a perfect solution to soundproof and fight the propagation of vibration between environments with different destinations. Isophon Wall™ bars can be delivered pre-drilled and ready to be installed.
