What Are Rockwool Sandwich Panels?
Composition and Structure
Rockwool sandwich panels have three main parts. The outer layers are steel sheets that add strength and protection. The middle layer is rock wool insulation, made from melted rock spun into fibers. This creates a light but strong panel with great insulation and durability.
Panels come in different thicknesses, from 50mm to 150mm, for various needs. They have tongue-and-groove edges, which fit tightly during setup. You can pick flat or wavy surfaces based on your design. Coatings like PE, PVDF, and HDPE make them last longer and resist rust.
These panels are very useful. They work in cold storage, clean rooms, and factories. Their design helps them stay strong in tough conditions over time.
