In marine application the system is type approved by EU MED, U.S. Coast Guard and MRA+approved for steel and aluminum structures. The system complies with SOLAS safety objectives and new IMO FTP Code fire test requirements; Res.A.754(18), Fire Resisting Division for High Speed Craft (HSC); Res. MSC.45(65), Non-combustible to IMO A 799 (19),  Surface burning characteristics (ASTM E 84) - Rating-Flame spread = zero, & smoke developed  = zero. The system is also approved by ABS (American Bureau of Shipping) for Steel and Aluminum structures.

Fyrewrap® Blankets are also available with one side or two side facing or encapsulated in reinforced aluminium foil / aluminum foil.


FyreWrap Marine Blanket from Unifrax is a totally inorganic, flexible, high-temperature insulation blanket specifically designed to provide passive fire protection for marine applications. The calcia, magnesia, silica chemistry is designed to enhance biosolubility. Unifrax’s proprietary fiber spinning technology combined with mechanical needling of the fibers eliminates the need for binders in the product. This results in a material with high tensile strength and superior thermal and acoustical properties. FyreWrap Marine Blanket is chemically stable and its thermal properties are unaffected after exposure to water immersion or high humidity.The blanket is offered as 6 pcf or 8 pcf density and available in .5”, 1.0”, 1.5”, and 2” thickness’. It is installed by impaling the blanket over insulation pins welded to the steel wall or deck surface. This material offers superb insulation value in a flexible lightweight noncombustible form. This offers builders and owners reduced structure weight, which may yield increased vessel speed, fuel savings, and available payloads.

FyreWrap Marine Blanket offers systems:

  • That are USCG Certified for steel and aluminum structures.
  • That comply with SOLAS safety objectives.
  • That meet IMO FTP code fire test requirements, Res. A.754(18).
