Product Overview
Rock wool sandwich panel is a load-bearing insulated panel made of two pre-painted galvanized steel sheets bonded to a high-density rock wool (mineral wool) core. It combines fire safety, thermal insulation and structural strength in one product.
Because rock wool is non-combustible (A1/A2 fire class), this panel is the first choice for warehouses, factories and cold-chain buildings where fire regulations apply. Panels are produced continuously and cut to your project length, ready for fast on-site installation.
Key Features
- A-grade fire resistance — non-combustible rock wool core meets strict fire codes
- Thermal & acoustic insulation — thermal conductivity as low as 0.038 W/(m·K) with sound reduction up to 30 dB
- High strength — rock wool core bonded at 90° gives excellent shear and peel strength
- Fast installation — tongue-and-groove joints, panels up to 12 m long, no wet trades
- Weatherproof coating — PE / SMP / PVDF pre-painted steel, 15+ years coating warranty
