Rockwool Mattresses, also known as Light Resin Bonded (LRB) mattresses, are flexible insulation products manufactured from stable rock fibers bonded with a minimal quantity of thermosetting resin and reinforced with metal wire mesh.
These mattresses are easy to handle, cut, resize, and shape, making them ideal for insulation of irregular surfaces, curved equipment, and high-temperature industrial installations.
