Marine insulation

A safe, efficient and sustainable solution that maximize the peace of mind for ship builders, passengers and operators

Health and safety are the basic rules of maritime industry, next to upholding pristine levels of comfort. But that can come at a high cost, especially when it comes to energy. How can shipbuilders sustainably tackle the cost and risks related to energy infrastructure as early as in the ship design?

A stable and healthy indoor climate requires an efficient and reliable level of cooling, heating, and ventilation – based on healthy materials. When it comes to cooling, condensation is a common, yet dangerous enemy that can lead to the formation of harmful fungi, corroded systems and poor air quality. Insufficient or inefficient heating systems can also result in high energy and maintenance costs.

At Thermaflex, we understand those challenges, and tailor our solutions accordingly. We offer a wide range of innovative insulation systems to meet every possible need – harmonizing comfort, capital and climate with easy-to-install thermal condensation free solutions. Our non-toxic polyolefin-based ThermaSmart Marine 2.0 Black ranges ensure minimal smoke production in case of fire, making it the safest choice to guarantee visibility and minimize risks of intoxication or breathing problems. The ultra-light weight material can significantly cut the weight load on ships, making it possible to increase carrying capacity. Another key aspect of the material is its water-tight barrier, with minimum condensation risk, thus ensuring maximum performance and lifetime of the air and water distribution systems.
