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.
SHREEROCK mattresses manufactured from selected rocks to State of the Art Specification fully conform to national and international standards such as
