Cruise ships

Don’t let insulation weigh down vessel design

Energy-efficient insulation for cruise ships: reducing fuel consumption and operational costs

As cruise ships become larger – and heavier – it’s vital to retain operational efficiency. Our insulation solutions significantly reduce overall vessel weight, helping you lower fuel consumption, improve energy efficiency, and cut OPEX without compromising your design ambitions.

As well as this, the right insulation choices play a critical role in enabling more sustainable shipbuilding. By maximising design flexibility, our solutions support the integration of eco-friendly technologies alongside luxury amenities. This helps you meet tightening regulations while delivering the luxury experience passengers expect.
