Marine insulation

Stable, healthy indoor climate

Passengers on board ships want to feel safe and comfortable. A stable, healthy and pleasant indoor climate is a very important part of this. This demands heating, cooling, air conditioning and ventilation that function perfectly. Poor or damaged insulation of the HVAC/R systems is a risk factor. They will perform less effectively, will need additional repairs and maintenance and will waste energy. In addition, condensation can lead to harmful mould, oxidation and corrosion of pipes, leaks, hygiene problems, wet floors and ceilings and poor air quality.

A complete solution

To ensure the desired comfort level and avoid high energy and maintenance costs, we have developed a complete insulation solution for shipbuilding. The basis is a thermoplastic elastomer insulation in the form of pipe insulation and sheets with a black aluminium protective layer. These lightweight materials are usable across a wide temperature range and offer excellent long-term insulation value. Due to their closed cell structure and the integrated water vapour barrier, no condensation occurs, even if the insulation is slightly damaged. The high mechanical strength, specifically tear and compression resistance, also protects against damage and noise from mechanical vibration.
