2 Product Features

Rock Wool Wall Sandwich Panels are revolutionizing the construction industry with their exceptional blend of safety, efficiency, and sustainability. Engineered for superior performance, these panels feature a core of rock wool—a natural, Class A non-combustible material—delivering a fire resistance exceeding 4 hours. This robust fireproofing makes them a trusted solution for safeguarding structures like warehouses, schools, and healthcare facilities against fire risks.

Boasting a density of 80kg/m³ to 150kg/m³—typically 120kg/m³—these panels offer a compressive strength of ≥150KPa. Encased between two durable steel sheets, they provide outstanding resilience, standing firm against harsh weather conditions while ensuring structural stability. This high-strength design makes them perfect for projects demanding longevity and reliability.

When it comes to thermal insulation, Rock Wool Wall Sandwich Panels excel. The rock wool core, with a thermal conductivity of ≤0.043W/(m·K), paired with polyurethane (PU) edges at ≤0.025W/(m·K), creates an energy-efficient barrier. This keeps interiors cozy during winter and refreshingly cool in summer, slashing energy costs for heating and cooling—a boon for eco-conscious builders.

Noise reduction is another key advantage. The panels’ porous composition absorbs and deflects sound waves, offering top-tier soundproofing for environments like auditoriums, offices, or hospitals where silence is golden. Additionally, their eco-friendly profile shines through: crafted from recyclable, inorganic materials, they align with green building standards, leaving a minimal environmental footprint.

Installation is a breeze with these prefabricated panels, allowing crews to cover 600㎡ to 800㎡ daily. This speed accelerates project timelines and cuts labor expenses, making them a cost-effective choice. For architects and contractors seeking fire-resistant building materials, thermal insulation panels, or soundproof construction solutions, Rock Wool Wall Sandwich Panels deliver unmatched versatility and performance, redefining modern construction excellence.
