The U SeaProtect range provides superior marine acoustic insulation, as well as thermal and fire protection, for a wide range of applications from cruise ships to offshore and OEM marine constructions. 

Using a unique patented technology based on 20+ years of R&D, ISOVER developed new-generation ULTIMATE™ mineral wool that combines all advantages of glass wool and stone wool for efficient marine acoustic insulation, as well as fire and thermal insulation. ULTIMATE™ mineral wool products have excellent sound absorption properties thanks to the unique internal micro-structure of the insulation mats comprising long interwoven fibers. ULTIMATE™ acoustic insulation materials also have higher air-flow resistivity values, from density 24 kg/m3 onwards, compared to traditional marine stone-wool products.

How can you achieve even better marine sound insulation results?

Quietude constructions are turnkey solutions for specific areas on board of your ship such as the engine/machinery rooms, discos, theatres, cinemas, designed to achieve high sound reduction performance levels (up to 53-54 dB). These constructions increase sound protection in the critical medium-low frequency range to provide technical solutions that significantly reduce noise levels. 

ISOVER’s quietude sound-barrier insulation is obtained by combining SeaProtect dB-Flex Alu sound protection membrane with other U SeaProtect acoustic insulation materials. This membrane is made from a visco-elastic polymer topped with reinforced Alu facing. By applying this membrane, you can increase the sound protection of a standard SeaProtect construction to 53dB (vs. 48dB). 

  • Significantly enhance noise reduction, by up to 53dB

  • Optimize your thermal and fire protection at the same time with ULTIMATE™ products

  • Install adapted sound-dampening insulation quickly and easily

How does Sea Protect dB-Flex work?

This acoustic insulation solution is based on the “mass-spring-mass” principle:

Sea Protect dB-Flex Alu plays the role of “mass”, reflecting some of the sound and letting the rest through
Sound is transmitted to the flexible insulation and U SeaProtect acts as damper absorbing and reducing the amplitude of the acoustic waves
The steel plate reflects back some of the sound into the insulation, which reabsorbs it;
The sound transmitted to the adjacent room is significantly attenuated
