Rock Wool Type A Sound Absorbing Lining Panel for B15 Class

Rock Wool Type A Sound Absorbing Lining Panel for B15 Class

Product Introduction:

The Type A Sound Absorbing Lining Panel is a high-performance acoustic treatment panel specifically engineered for marine, industrial, and commercial environments where noise reduction and fire safety are critical. Unlike standard soundproofing panels that block noise transmission, this sound absorbing panel is designed to reduce reverberation and echo by trapping and dissipating sound energy within its structure.

Featuring a Type A construction with perforated steel facers on both sides and a high-density sound-absorbing core, this panel meets SOLAS (Safety of Life at Sea) requirements and IMO FTP Code Part 3 for A-class divisions. It is ideal for installation on bulkheads, deckheads (ceilings), and machinery space linings where noise control is essential for crew comfort, communication safety, and regulatory compliance.

The panel works on the principle of porous absorption: sound waves enter through perforations in the steel facer, penetrate the acoustic core, and are converted into minute amounts of heat through friction within the fibrous or foam structure. This significantly reduces reflected noise, lowers overall decibel levels, and improves speech intelligibility in enclosed spaces.

Typical applications include engine room linings, pump rooms, auxiliary machinery spaces, ventilation rooms, accommodation corridors, cinemas, control rooms, and public address zones on cruise ships, ferries, naval vessels, and offshore platforms. The panel is certified by major classification societies including DNV, ABS, Lloyd's Register, Bureau Veritas, and CCS, with fire ratings available from B-15 up to A-60.
