Overview
System Advantages & Features
Integrated Acoustic Solution: Combines sound-absorbing rockwool and a facing panel in a ready-to-install system, simplifying design and procurement.
Modular & Flexible: Easy to install on-site, cut to fit around obstacles, and panels can be removed for access to underlying services.
Enhanced Fire Safety: When used with non-combustible faces and rockwool core, the system can achieve required SOLAS A-Class fire ratings.
Durability & Maintenance: The metal facing provides a robust, easy-to-clean surface suitable for marine environments.
Improved Indoor Environment: Effectively reduces reverberant noise, enhancing speech intelligibility and crew comfort.
Typical Marine Applications
Cabin & Accommodation Bulkheads: For noise control between living quarters.
Ship’s Office & Conference Rooms: Where speech privacy and low background noise are required.
Hospital & Sick Bay: Requiring a quiet healing environment.
Machinery Control Rooms (ECR): To protect operators from engine room noise.
Mess Rooms & Recreation Areas: To improve acoustic comfort.
Feature:
Rock wool is an excellent thermal insulation material. Due to its unique structure and physical properties, it can effectively prevent heat loss and conduction, thus improving the thermal insulation performance of ships and saving energy resources.
As an excellent fireproof material, marine rock wool can withstand thermal radiation at high temperatures, preventing the spread and wave of fire, reducing the harm of fire and safeguarding the safety of people and property.
In the marine environment, the surface of the marine rock wool material is susceptible to erosion by seawater, wind, sand, sunlight and other factors, but because of the qualities of the rock wool itself and the role of the surface anticorrosion coating, so that it has a very excellent corrosion resistance, prolonging the service life.
Rock wool has good heat preservation performance and will not be affected in low temperature environment. It can effectively maintain the temperature inside the ship and provide a comfortable working and living environment for the personnel.
Rock wool is a material with environmental protection performance, does not contain any harmful substances and short fibers, in line with environmental standards, will not cause pollution to human health and the environment.
