LRB MATTRESSES
Rockwool Lightly Resin Bonded (LRB) mattresses are made of mineral fibers lightly bonded with resin and faced on one side with galvanized or stainless steel wire mesh. It is a flexible material with firm structure and excellent thermal insulation properties.
LRB mattresses are non-combustible in nature, reinforced with wire mesh, and used extensively for high-temperature insulation in industrial equipment.
