Our insulation solutions on board Icon of the Seas

The Icon of the Seas, built by the Meyer Turku shipyard in Finland on behalf of Royal Caribbean International is yet another ship that breaks all records. This maritime masterpiece stretches an impressive 365 meters long, reaches a dizzying height of 20 decks and a width of 64 meters. With a gross tonnage of 250,800, Icon of the Seas is a testament to a new era in the cruise industry.
Designed to accommodate 5,610 passengers in 2,805 cabins, Icon of the Seas also has a dedicated crew of 2,350. 
We are proud to have been chosen as a partner for such a large-scale project and to contribute with different insulation solutions.

A diverse range of solutions to meet all the insulation needs of the vessel

First, for the fire protection of the steel divisions, our U SeaProtect® light stone wool solutions emerged as an obvious choice, offering the best performance-to-weight ratio compared to competing insulation solutions - an essential criterion on a liner where the weight of construction is one of the big challenges. Thus, 200,000 m² of U SeaProtect® were used to insulate the bulkheads and decks. Then, in areas which did not require fire-resistant performance, but where thermal comfort was the main issue, our SeaComfort glass wool was favoured - with another 180,000 m² of insulation deployed throughout the vessel!
In addition to our insulation solutions, the customer chose flooring solutions from our sister company Weber. 
And the icing on the cake, our brand-new self-supporting duct solution Sea CLIMAVER® was chosen for the HVAC ducts of a restaurant area!

Sea CLIMAVER®: Testing a new solution - a game changer in maritime innovation?

Backed by over 50 years of use in land-based construction, Sea CLIMAVER® is the special adaptation for maritime use of our iconic CLIMAVER® self-supporting duct. An ultra-rigid glass wool panel, Sea CLIMAVER® constitutes in itself an insulated duct, and allows shipbuilders to build HVAC ductwork without metal duct. Still new on the maritime market, this solution convinced the shipowner Royal Caribbean and the Meyer Turku shipyard, who chose to implement it in a test area as part of this project.


Reduce the environmental impact of the HVAC system

Challenged with its environmental footprint in the face of climate change, the cruise industry is constantly making progress in adopting cleaner technologies and operational practices. For a project like Icon of the Seas, Royal Caribbean sought to set a new standard by adopting cutting-edge innovations such as advanced propulsion systems, waste management solutions and energy-efficient designs.
Sea CLIMAVER® fits perfectly into this approach, reducing the energy consumption of HVAC systems by around 15%, an argument that convinced the customer given that HVAC generally represents 30% of a ship's total energy consumption. Additionally, it provides up to 65% less weight compared to a traditional duct system, very appreciable on a vessel where the overall weight is directly linked to fuel consumption and CO2 emissions.

Contribute to thermo-acoustic comfort on a luxury vessel

A high-performance solution in terms of thermal insulation, notably thanks to the best airtightness in its category, Sea CLIMAVER® also provides the best in terms of acoustic comfort. Where both thermal and acoustic comfort are crucial factors for the well-being of travelers, Sea CLIMAVER® directly contributes to a more peaceful and pleasant experience on board.

Increase productivity during the construction phase

Although this pilot project only encompasses a 1600 m² restaurant area, this was enough to convince the Meyer Turku shipyard of the many advantages that the Sea CLIMAVER® solution offers in terms of installation and logistics:

  • The installation time could be greatly reduced, because instead of having to install a metal duct and subsequently insulate it, the system could be installed in a single operation offering speed of installation and flexibility. 
  • Added to this were the logistical advantages, notably saving space during transport and storage and reducing waste. 

The test results were positive! The duct system exceeded our expectations in terms of weight savings compared to traditional thin-walled steel ducts. Also, the sound absorption properties of Sea CLIMAVER® allowed us to do without additional silencers on the ducts, which reduced the overall installation cost.

All of these properties of Sea CLIMAVER® could be demonstrated through this project which promises to offer enormous potential for other large-scale projects where planning, installation costs and streamlined logistics are the name of the game.

Building Together: A Collaborative journey beyond conventional practices

As part of our collaboration on the Icon of the Seas project, we were able to experience a true partnership relationship with the various stakeholders, calling into question the usual practices of shipbuilding. Beyond providing insulation, we participated in an exceptional innovation and construction process, in the constant search for improvement and efficiency. The good relationships our team in Finland was able to establish with Meyer Turku and Royal Caribbean through previous projects, as well as ongoing technical support, have been key factors in this success.
We are grateful that the shipowner and the shipyard have taken the challenge of testing our new Sea CLIMAVER® solution, which we are convinced will establish itself as a new standard for HVAC ducts in tomorrow’s shipbuilding industry.
