ROXUL® products are mineral wool fibre insulations made from basalt rock and slag. This combination results in a non-combustible product with a melting point of approximately 2150°F (1177°C), which gives it excellent fire resistance properties. ROXUL® mineral wool marine boards and blankets are water repellent yet vapour permeable materials. Installations on below ambient, cool surfaces will require a vapour retarder system.


Roxul® Inc. manufactures a series of non-combustible mineral wool products designed for thermal and fire protection required in marine applications. Its products have been tested by SOUTHWEST RESEARCH INSTITUTE® to comply with the latest IMO/FTP Code and have Certificates of Approvals from the United States Coast Guard, Transport Canada and Lloyd’s Register. The RHM series of marine insulations are manufactured in 3 through 10 pounds per cubic foot (48 through 160 Kg/m3) densities. In addition, RHM Series Marine Board & Blanket insulations are suitable to a full range of temperature applications including boilers, vessels, tanks, ducts, ovens, mufflers, and exhaust stacks.
