ThermaSmart® Marine 4.0: Smarter. Safer. More Sustainable.
This release introduces an innovative solution for modern marine insulation needs. With enhanced performance, safer materials, and simplified installation, ThermaSmart® Marine 4.0 is ready to support the next generation of sustainable, efficient vessels.
Any leakage in the ventilation duct can result in the escape of air, but also of sound. The critical parts of a ventilation duct for leakage are the connections. Due to differences in heat and cold between the air in the duct and that of the surrounding space, there is slack on the connections. So: choose flexible connections that continue to close well, even when the ducts move.
Thermaflex’ TQ-Air connections are made of rubber, which makes them easy to install and prevents the ventilation duct from leaking.
