Rock Wool Board Panel for Sandwich Panels

1. Integrated Structural Core
 When bonded to metal skins, the rock wool acts as the "web" of an I-beam, providing the panel with high stiffness and the ability to span long distances between structural supports.

2. Fire Rating Excellence
As a non-combustible material (Class A1), it is the preferred core for fire-rated partitions and external walls in industrial plants, warehouses, and data centers.

3. Thermal and Acoustic Dual-Benefit
It offers a low thermal conductivity to maintain internal temperatures and a high density that effectively blocks industrial noise and prevents sound reverberation.

4. Precision Manufacturing
These boards are produced with extremely tight thickness tolerances and high surface flatness to ensure a perfect, void-free bond with the metal skins and adhesive.

5. High Compressive Strength
Designed to resist the pressure of the lamination process and the external loads (such as snow or wind) that the final sandwich panel will face in the field.
