Glasswool / LRB Insulation

LRB MATTRESSES WOOL

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.
LRB 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.

LRB 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. .

Thermal conductivity varies with the Temperature and Density of insulation as shown in the graph.

LRB Mattresses are available with wired mesh on one or both sides in SS or GI.

Non-hygroscopic, non-capillary and does not absorb any moisture from the air. Moisture has no effect on the stability of the mattresses.

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).

LRB MATTS mattresses are packed in HDPE bags.

Mattresses do not cause, initiate or promote any kind of corrosion.

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.

• Incombustible
• Good acoustic properties
• Moisture resistant
• Fire retardant
• Neither cause nor accelerate corrosion
• Chemically inert
• Durable and do not sag and settle
• Easy to handle and apply
• Better Insulation properties
