Product Details
Rockinsul RB slabs are semi-rigid and rigid boards manufactured from stable rock fibers bonded with a minimum quantity of thermosetting resin binder. ROCKINSUL RB slabs are capable of withstanding extreme temperatures up to 750 °C and are lightweight, strong, resilient, easy to handle, and easy to cut to suit intricate shapes.
Working temperature Fiber: Up to 750 °C Facing: 100 °C At temperatures in excess of 230 °C, a limited migration of binder may occur in the insulation in contact with the hot face. This does not impair the insulation performance.
Features
Acoustic performance
