Marine engine rooms, exhaust systems, and machinery spaces present a uniquely demanding thermal environment: high heat, constant vibration, salt-laden humidity, and tight crew quarters. Insulation is essential to crew safety, fire protection, fuel efficiency, and regulatory compliance on vessels of every size—from workboats and tugs to commercial ships, yachts, and naval vessels.
Marine Insulation Applications
- Main propulsion engine exhaust manifolds, turbochargers, and dry stacks
- Auxiliary generator exhaust systems
- Boiler and steam piping
- Fuel oil heaters, lube oil coolers, and HVAC ducting
- Machinery space acoustic treatment
- Personnel protection on hot piping and valves
Unitherm’s Marine Insulation Solutions
Unitherm builds removable, reusable insulation covers engineered to meet the rigorous requirements of marine service—including SOLAS fire-safety standards, USCG approvals, and the demands of saltwater environments. Our blankets are CAD-templated to fit complex engine room geometry and designed for rapid removal during inspections, surveys, and repairs.
Our marine product line includes high-temperature dry-stack exhaust insulation, fire-rated covers for machinery spaces, acoustic blankets that reduce engine room noise levels, and corrosion-resistant outer fabrics designed to shed salt spray and moisture.
Key Benefits
- Protect crew from burn hazards in confined engine rooms
- Reduce ambient temperatures and improve habitability
- Lower noise levels in machinery spaces and adjacent cabins
- Meet SOLAS, ABS, and USCG fire and thermal requirements
- Simplify class surveys with quickly removable covers
From new-build shipyards to repair facilities and fleet operators, Unitherm engineers marine insulation that delivers safety, efficiency, and long service life. Contact our marine team to discuss your vessel or program.
