Maris Tech: Low-Thickness Thermal Insulation for Marine Designers and Shipyards

Why Thermal Insulation Is Important in the Marine Industry

On boats and vessels, thermal insulation affects not only comfort but also the quality and durability of interior environments.

Proper surface protection can help to:

• improve onboard thermo-hygrometric comfort
• reduce the risk of surface condensation
• limit moisture-related issues
• reduce thermal dispersion
• increase the energy efficiency of air-conditioned spaces
• better preserve internal surfaces and structures

In marine applications, available space is often limited and geometries are complex. For this reason, low-thickness insulation systems represent a particularly interesting solution.

How Spray-Applied Low-Thickness Marine Insulation Works

MARIS TECH is a water-based nanocomposite thermal coating formulated with hollow ceramic microspheres. Sprayed directly onto the vessel’s internal surfaces, it creates a thin, uniform, and seamless layer that easily conforms to curves, stiffeners, joints, and intricate structural shapes.

Its insulating action helps reduce thermal transfer across surfaces and regulates surface temperature, thereby limiting the risk of condensation formation. The heat-reflective properties of the coating also work to enhance indoor comfort and reduce the energy load required for air conditioning and heating.

Thanks to its spray application and low thickness—typically between 1 and 4 mm—MARIS TECH allows for the treatment of areas where traditional panels and blankets would require extensive cutting, fitting, and adjustment. This makes it an ideal low-thickness thermal insulation marine industry solution for hulls, cabins, technical spaces, engine rooms, and refit projects.

Why Choose a Low-Thickness Solution in the Marine Industry

In the marine sector, every available centimeter counts.

For this reason, a low-thickness insulation system offers a concrete advantage over more bulky traditional solutions, especially when working in existing spaces or technical areas with limited access.

A solution of this type allows you to:

• Easily preserve original structural geometries

• Minimize the spatial footprint of the intervention

• Treat surfaces that are difficult to cover with traditional panels or materials

• Optimize installation in technical or hard-to-reach environments

How to Eliminate Onboard Condensation with Maris Tech Low-Thickness Marine Thermal Insulation

MARIS TECH forms a continuous 1–4 mm coating that helps control surface temperature and reduces the risk of condensation on the internal metal surfaces of the hull.

Anyone who lives or works on boats knows it well: condensation is one of the most insidious enemies in marine environments. Moisture, mold, unpleasant odors, and even the risk of structural corrosion are the direct consequence of thermal fluctuations between the inside and outside of the hull.

Traditional insulating materials (such as rock wool, rigid foam, or polystyrene) often show clear limitations in marine applications: they occupy valuable space, risk absorbing moisture over time, and require complex installations to fit the boat’s geometry perfectly.

This is where Maris Tech makes the difference.

Why Choose Maris Tech over Traditional Insulation?

When it comes to low-thickness thermal insulation for the marine industry, Maris Tech redefines onboard comfort and protection standards by addressing the condensation problem at its root.

• Minimal thickness, maximum performance: Unlike conventional panels that steal precious space in living areas or technical compartments, Maris Tech delivers extraordinary effectiveness in a fraction of the space, preserving the vessel’s original interior volumes.

• Continuous anti-condensation barrier: Condensation forms when water vapor meets a cold surface (the “dew point”). Maris Tech disrupts this thermal bridge without leaving air pockets or imperfect joints, preventing the formation of water droplets.

• Zero water absorption: Many traditional insulation materials struggle in marine environments and end up soaking up water, losing their insulating power and promoting mold growth. Maris Tech is water-repellent and resistant to moisture.

• Perfect adhesion to any geometry: Hulls, bulkheads, curves, and complex angles are difficult to cover with rigid panels. Maris Tech conforms seamlessly to the surface, eliminating the air pockets where moisture usually accumulates.

• Lightweight and durable: Reducing weight aloft and onboard improves vessel performance. Maris Tech guarantees long-lasting insulation without weighing down the boat.

The result? Dry interior spaces, healthy air, absence of mold, and a comfortable microclimate in both summer and winter—without sacrificing onboard living space.
