Remak® Stonewool – The optimal soundproofing, insulation, and fire-resistant solution for cruise ships. B1-certified, marine-durable, and ideal for modern shipbuilding
Cruise ships are constantly exposed to high levels of noise and fire risks. Remak® Stonewool (also known as mineral wool or rock wool) is the optimal solution for soundproofing, thermal insulation, and fire protection on cruise ships—ensuring safety, performance, and environmental compatibility in marine conditions.
Remak® Stonewool also known as mineral wool or rock wool, slag wool – is a familiar and essential material in the shipbuilding industry Vietnam – A rising power in global shipbuilding
With over 3,000 km of coastline and more than 90 seaports, Vietnam is one of the top 10 shipbuilding nations globally. Although still young, the Vietnamese shipbuilding industry holds a 0.61% share of the global market.
To maintain momentum, local shipbuilders must adopt advanced materials that meet international standards for marine fire safety, sound insulation, and environmental sustainability.

Remak® Stonewool meets international standards for marine fire safety, sound insulation, and environmental sustainability.Remak® Stonewool – World-class quality for marine applications
Remak recently completed a major order of 1,000 packs of Stonewool insulation for a leading cruise shipbuilder in Vietnam. This is not only a milestone contract but a testament to our product quality and the trust we’ve built within the industry.
Also known as stone wool, mineral wool, or thermal-acoustic insulation, Remak® Stonewool is engineered with outstanding features:
- High-performance sound and thermal insulation
- International B1 fire-resistance certification
- Marine-environment friendly, long-lasting durability
- Exceptional lifespan, resistant to corrosion and harsh marine climates
The challenge of noise & fire safety on modern cruise ships
Modern cruise ships require not only luxury and comfort but also advanced safety standards:
Engine noise: Constant operation of engines generates significant noise, which easily spreads through steel structures.
- Entertainment zones: Loud music from bars and lounges can disturb guest cabins.
- Fire hazards: Complex electrical systems and regular welding activities increase fire risk.
As a result, shipbuilders must choose materials that offer both fire resistance and superior acoustic & thermal performance.

Remak® slag wool offers both fire resistance and superior acoustic & thermal performanceWhat is Remak® Stonewool?
Remak® Stonewool is produced by melting basalt rock and blast furnace slag at ~1,500°C, then spinning the molten mixture into fibers.
Key advantages include:
- High sound absorption and thermal insulation
- Fire-resistance rated B1 – does not support flame spread
- Lightweight with high mechanical strength
- Water-resistant, rot-resistant
- Safe for health and eco-friendly for marine use
