Rockal
ROCKAL Performed Pipe Section are made of rockwool fibers spun from molten basaltic rocks bonded together by a thermo-setting resin binder. The fibers are molded around the pipes of different standard diameter at the required thickness and dried to form rigid hollow cylinder insulation, which then is linearly slit to allow easy installation.
ROCKAL Performed Pipe Section is used over a very wide range of temperatures to insulate all sizes of cold and hot piping. Like domestic water in buildings and chemical process such as in oil refineries, chemical and Petro-chemical insulation and desalination plants, HVAC chilled water systems, oil pipelines. ROCKAL Pipe Section used as acoustic insulation of pipelines where gas fluids or solid particles are transferred in high velocities.
ROCKAL Rockwool Pipe Section comes non-faced or faced with reflective vapor barrier material (Reinforced Aluminum foil FSK).
ROCKAL Rockwool fibers products are classified as Non-Combustible materials and follow the fire safety rating achievements: - Class 1 Surface spread of flame in accordance to BS 476 - Class 0 in accordance to BS 476 - Class A1 in accordance to European Standards - Surface burning characteristics in accordance to ASTM E-84 - Fire Spread Index: Less than 10 - Smoke Developed Index: Less than 25
