Isover carried out the thermal and acoustic insulation of the “Wonder of the Seas”, the largest ocean liner in the world

An extraordinary shipyard for an extraordinary liner

Known at Chantiers de l'Atlantique as "C34", its hull number, this mastodon 362 meters long and 64 meters wide displays, according to its owner, the American company Royal Caribbean International (RCI), impressive figures and excessive:

At a cost of more than one billion euros, the Wonder of the Seas, whose assembly began in October 2019, was launched for sea trials in September 2020. The first cruises to board are scheduled for spring 2022.

A range of ISOVER solutions to meet all the ship's insulation stations

Particularly drastic, fire safety standards on board are an essential issue in shipbuilding. The U SeaProtect® range of products, made from lightweight ULTIMATE® stone wool, provided the optimum response with a new generation of high performance mineral wool that combines all the advantages in terms of fire, thermal and acoustic insulation. , with substantial weight savings.

2/3 of the insulation, i.e. 50 m², was carried out with U SeaProtect® to ensure thermal comfort and passenger safety

For this large-scale project, the U SeaProtect® product was chosen for its excellent results in all aspects: its thermal performance, which guarantees a strong increase in energy efficiency while significantly reducing operating costs and emissions of CO₂. In addition, U SeaProtect® is an exceptionally light weight solution: -25% compared to conventional mineral wool insulation. Also, the product is packaged with compressed and highly streamlined packaging, allowing for logistical savings and easy installation on site.

U SeaProtect® also meets the most demanding standards for fire protection, ranging from the highest level of reaction to fire to excellent fire resistance qualities.

100 m² of PI Marine insulation panels for high thermal and anti-condensation performance

Faced with thermal and condensation issues, ISOVER proposed the PI MARINE range in glass wool. Exclusive on the market, it was essential for thermal insulation and ensuring an anti-condensation role.

3 products were placed on different positions in the ship:

• PI662, an aluminium-faced glass wool panel which was used to insulate the hull and ensure anti-condensation on the hull.
• PI682 made it possible to insulate a large part of the network of ventilation ducts.
• PI695, a draft shield has been installed between the cabins, on the ceilings and on the decks. Their role as a fire barrier prevents the spread of toxic fumes in the event of a fire.

A lighter ship that consumes less fuel

In the quest for bigger and faster ships, material weight and weight reduction in general have never played such an important role as they do today. With its lightest marine range in the world, ISOVER has enabled a -25% weight saving on insulation, for an identical result in terms of performance, thus contributing to the reduction of the environmental impact of the largest liner in the world. world, whose fuel consumption has been reduced.
