Lightly resin bonded mattresses (LRB) consist of fine fibres spun from a range of selected rocks melted at high temperature bonded with a thermosetting resin.\

Lightly resin bonded mattresses (LRB) are light weight, strong, resilient, and easy to handle and cut to suit intricate shapes.

Facings:

Lightly resin bonded mattresses (LRB) are available with galvanized or stainless steel hexagonal wire mesh on one side or plain.
