Product Description and Application
Marine Slabs are robust and high-density insulation material suitable
for hot surfaces up to 650°C that is manufactured from a blend of
natural rocks by melting at above 1600°C. They have a variety range of
insulation applications such as storage tanks, furnaces, autoclaves
and kilns, particularly marine structures and vessels such as floating
floors. They are excellent and cost effective for fire, thermal, electrical
and acoustic insulation.   Marine Slabs are made of moisture and water
repellent rockwool and available in density of 80, 100, 120, 150 and 200
Kg/M3.

Fire Resistance

Fire resistance is on the top priority list when choosing insulation materials.
Rapid spread of fire destroys building structures, and cost lives. Smoke and fumes can hinder escape and rescue. The ideal fire insulation materials should
not release toxic emissions or contaminate the environment. Rockwool marine slabs offer a high level of fire safety. When tested under new EU fire
classification system – for non combustibility to EN ISO 1182, the best A classification was achieved.

When tested in accordance with  GB9978, ASTM E-136,  Rockwool Insulation Boards 02-1, 02—2, 02-03 are categorized as “non-combustible” grade.
  • Ignitability                   None
  • Spread of Flame       None
  • Heat Evolved              None
  • Smoke released       None

Moisture Resistance
Rockwool marine slabs are water resistant.

Corrosion Resistance
Rockwool marine slabs are neutral in pH or slightly alkaline, and incapable of corroding steel. To maintain this condition, protection must be provided
against contamination from external sources.  

Chemical and Biological Characteristics
Rockwool marine slabs are in compliance with GB/T11835, ASTM C 795, JIS A 9504.  It has a pH of 7 or slightly alkaline, which does not support mold,
bacteria or fungi growth.
Compression Resistance

Rockwool marine slabs offer high resistance to
compression, combined with ready recovery to
nominal thickness when a normal compressive
load is removed. The graph shows the
reduction in thickness of Rockwool marine
slabs rigid bans under compressive load.
