QueenCore Rock Wool Sandwich Panels Projet

Transforming Luxury Cruise Interiors with Fireproof & Soundproof Rock wool Sandwich Panels

Setting the Standard for Safety and Serenity at Sea

In the demanding world of luxury cruise ship construction, where uncompromising safety, exceptional passenger comfort, and stringent regulatory compliance converge, the choice of interior materials is paramount. Our advanced Fireproof and Soundproof Rock wool Core Sandwich Panels are engineered to meet and exceed these rigorous demands, becoming the trusted solution for premium shipyards and interior outfitters globally. This case study highlights the pivotal role our panels play in shaping the modern cruise experience.

Luxury Meets Stringent Requirements

Luxury cruise ships represent floating cities, housing thousands of passengers and crew in close quarters. This environment presents unique engineering challenges:

1. Fire Safety: The paramount concern at sea. Materials must resist ignition, prevent flame spread, and limit smoke and toxic fume emission to ensure safe evacuation and containment, adhering strictly to SOLAS (Safety of Life at Sea) and IMO (International Maritime Organization) regulations.
2. Acoustic Performance: Passengers expect tranquility. Effective sound insulation between cabins, public areas, machinery spaces, and decks is non-negotiable for guest satisfaction and privacy.
3. Structural Integrity & Weight: Materials must be robust yet lightweight to optimize ship stability and fuel efficiency without compromising on durability for long-term service in a marine environment.
4. Speed of Installation: Shipyard timelines are critical. Prefabricated solutions that enable rapid, clean installation are essential to keep projects on schedule and budget.
5. Aesthetics & Hygiene: Surfaces must be visually appealing, easy to clean, and maintain a high-quality finish consistent with luxury branding.

Engineered Rock wool Core Sandwich Panels

Our factory produces state-of-the-art composite panels specifically designed to conquer these maritime challenges:

• Unmatched Fire Resistance: The core of our panels utilizes high-density, non-combustible rock wool (stone wool). This mineral fiber insulation boasts an inherently high melting point (exceeding 1000°C / 1832°F) and is classified as A1 or A2-s1,d0 (non-combustible / very limited combustibility) according to EN 13501-1, the gold standard for marine applications. This core effectively compartmentalizes fires, prevents flame spread, and significantly delays structural collapse, providing crucial time for evacuation and firefighting.
• Superior Sound Insulation: The dense, fibrous structure of rock wool excels at absorbing and dampening sound energy. Our panels achieve high Sound Transmission Class (STC) and Impact Insulation Class (IIC) ratings, effectively blocking airborne noise (conversations, music) and structure-borne noise (footsteps, machinery vibration) between cabins, corridors, and decks. This creates the peaceful ambiance essential for guest relaxation.
• Robust & Lightweight Construction: The sandwich design – a high-integrity rock wool core bonded between two durable steel facings (typically galvanized or stainless steel, often pre-finished) – delivers exceptional strength-to-weight ratio. This reduces overall vessel weight compared to traditional methods and provides excellent resistance to impact and damage during service and maintenance.
• Streamlined Installation: Prefabricated in precise dimensions according to shipyard blueprints, our panels enable a “dry” construction process. This drastically reduces on-site labor time, minimizes waste, and eliminates the mess associated with wet trades (like plastering). Panels are quickly installed using specialized profiles, accelerating project timelines significantly.
• Versatile & Aesthetic Finishes: The steel facings are available in a wide range of pre-coated finishes – from sophisticated metallics and woodgrains to high-gloss or matte solid colors – meeting the exacting design specifications of cruise ship interiors. These surfaces are durable, easy to clean, hygienic, and maintain their aesthetic appeal for the lifespan of the vessel.

Excellence in Action

In a recent project for a major European shipyard constructing a next-generation luxury cruise liner, our panels were specified for:

• Passenger Cabin Partitions and Ceilings: Providing critical fire separation and acoustic privacy between staterooms and from corridor noise.
• Crew Accommodation Bulkheads: Ensuring safety and necessary sound control in crew areas.
• Galley and Back-of-House Walls: Containing potential fire hazards and controlling noise from service areas.
• HVAC Duct Enclosures: Fireproofing essential services running through accommodation zones.
• Public Area Feature Walls: Combining safety performance with high-end aesthetics in lounges and restaurants.

Our factory worked closely with the shipyard’s design and engineering teams from the outset, ensuring panel specifications precisely matched the structural, fire safety, and acoustic requirements for each zone. Detailed shop drawings facilitated seamless integration with other ship systems.

Setting Sail with Confidence

The deployment of our Rock wool Core Sandwich Panels delivered significant, measurable benefits:

1. Enhanced Safety Certification: Panels consistently passed rigorous third-party fire safety testing (e.g., according to IMO FTP Code, EN standards), enabling the vessel to achieve full regulatory compliance with SOLAS and class society requirements (e.g., Lloyd’s Register, DNV). The non-combustible nature of rock wool provided unparalleled peace of mind.
2. Exceptional Acoustic Environment: Post-construction acoustic testing confirmed significant noise reduction between cabins and from public areas, directly contributing to superior guest comfort scores and positive reviews highlighting the tranquility onboard.
3. Accelerated Build Schedule: The prefabricated panel system reduced installation time for partitions and ceilings by an estimated 35-40% compared to traditional methods, contributing to the shipyard meeting its critical launch deadline.
4. Reduced Lifetime Costs: The durability, low maintenance requirements, and inherent fire safety of the panels contribute to lower operating costs and reduced risk over the vessel’s lifetime.
5. Design Flexibility Achieved: Architects appreciated the range of available finishes, allowing them to realize their luxurious interior visions without compromising on core performance requirements.
