Rockwool Mattress Rock wool lightly resin bonded mattresses (LRB) consists of fine fibers spun from selected rocks melted at high temperature and bonded with a thermosetting resin. They are Machine laid fiber lay pattern and are baked to form mattresses of predetermined density and thickness. Mattresses are then slit and stitched to specified dimensions . It has controlled thickness and density resulting in predictable heat losses. Rockwool mattresses manufactured from selected rocks to State of the Art Specification fully conform to national and international standards such as IS : 8183 - 1993 BS : 3958 Part - 3 ASTM:C592 - 80 APPLICATION Rockwool mattresses are used for Hot & Cold insulation to conserve energy It is used in the thermal insulation of large vessels, boilers, , equipment, ducts, flanges, valves and plants operating at high temperatures. SERVICE TEMPERATURE -50 to + 750 DEGREE CENTI GRADE FIRE RESISTANCE Non-combustible when tested in accordance with BS - 476 part - 4 and ASTM E - 136. Class1 when tested in accordance with BS - 476 part 7, (ASTM E- 84). COROSSION RESISTANCE Mattresses do not cause, initiate or promote any kind of corrosion FACING LRB Mattresses are available with wired mesh on one or both sides in SS or GI. PACKING LRB MATTS mattresses are packed in HDPE bags. MOISTURE Non-hygroscopic, non-capillary and does not absorb any moisture from the air. Moisture has no effect on the stability of the mattresses. FLEXIBILITY Mattresses are very flexible. They will essentially retain thickness while conforming to any irregular shape. Retention of fibers by wire mesh prevents cracking or breaking of mattresses. BENEFITS OF ROCKWOOL Incombustible Good Acoustic Properties Moisture Resistant Fire Retardant Neither cause nor acelerate corrosion Chemically Inert Durable and do not sag and settle Easy to handle and apply Better Insulation Properties Standard Dimensions 1.640 X 1.220 M Thickness - MM 25,40,50,60,65,75,100 Density (Kg/M3) 100, 120, 128, 144, 150 Wire Netting 1/2"X22G, 3/4"X24G, 1"X20G Specification As per IS:8183 Test Method As per IS:3144 Max Service Temperature 750°c
