It is a stone wool blanket used in ship and sea construction, cofferdam walls, fire partitions, fire doors and ship interior installations for sound insulation and fire safety purposes.
Noncombustibility of Stone Wool Ship Blankets enables them to be used for thermal, sound and fire insulation of very high temperatures. The blankets are cut to size and wrapped around the surface to be insulated. The joints are laced with galvanized wire by passing it through the eyes of the wiremesh. Care should be taken to ensure that the joints fit properly and no gap is left at the joints. During the application on large surfaces, the blankets should be impaled over welded pins of 5-6 in number per square meter. The blankets are held in position by placing retaining washers over the pins. These pins also work as spacers for the insulation between the sheet metal cover and the insulated surface.
There are 3 different blanket types available as Marine Firebatts 32 (MF 32), Marine Wired Mat 80 (MWM 80), Marine Wired Mat 125 (MWM 125).
