BILLYTEX Sound Damping System

Introduction

- Sound Damping Floor Systems are innovative products in reducing the transmission of noise and vibration,
by to the ideal structures consisted of various components. These compositions are as below described.

Characteristics

1. Constrained visco-elastic vibration damping systems

- The Deck Composition & Steel Tiles constrained visco-elastic damping construction applied on top of the deck plates is the solution to reducing the radiated sound power from the deck. The resonant vibration of the deck is decreased by increasing the loss factor of the construction. This system provides an extremely high sound reduction, which far exceeds all similar systems. This unique vibration damping construction consisted of Visco-elastic and Deck composition or Steel tiles as constraining layer.

■ 1mm Visco-Elastic + 8~15mm deck composition Layer
■ 1mm Visco-Elastic + 1.5~2.0mm steel tile (floor)
■ 1mm Visco-Elastic + 1.5~2.0mm steel tile (Wall & DeckHead)

2. Sound reducing Floating Floors

- It is a combination of a constrained visco construction and a floating floor construction. This system provides extremely high sound reduction in the low frequency area. The marine slab was specially developed by processing Rock wool which also has high fire-resistance performance, thus they provides a significant improvement over conventional marine slab. They also have extreme tensile strength and durability.

■ Min. 20mm Rock-wool + 25mm Compound (A60)
■ Min. 20mm Rock-wool or Mineral-wool + 3mm steel plate (or AL)

3. Constrained visco-elastic vibration damping systems

- Special attention should be addressed to areas in the vicinity of the engine room, propulsion system, above discotheques and below areas with high level of human activities, which are exposed to both airborne, impact
and structure borne noise. In these noise sensitive areas, there will be a strong need for noise reducing measures, such as insulation, and noise reducing floorings principles. A suitable floor construction with good noise reducing properties throughout the frequency range and especially in the low frequency range is the combined visco-elastic and floating floor systems. DAE HYUP’s visco-elastic system are also used under teak decks, to reduce the propagation of impact noise to the below areas.
