What Are Sandwich Panels?
Sandwich panels are a composite building material consisting of a lightweight insulating core (rock wool, polyurethane, or glass wool) bonded between two high-strength metal facings (galvanized steel or aluminum). This unique structure provides exceptional thermal and acoustic insulation, structural rigidity, and fire resistance. Our sandwich panels are manufactured using state-of-the-art continuous lamination technology, ensuring uniform thickness and superior bonding strength.
Key Features of Our Insulated Sandwich Panel
Superior Insulation Core Choose from high-density rock wool sandwich panel for A-class fire resistance, or PIR/PU foam for optimal thermal efficiency. Our rock wool sandwich panel is non-combustible and provides excellent sound absorption.
High-Strength Facings Made from premium galvanized steel or aluminum, coated with durable PVDF or polyester paint for long-lasting color retention and corrosion resistance.
Perfect Seal Design The unique tongue-and-groove joint ensures a tight, weatherproof seal, preventing thermal bridging and air leakage. This makes our sandwich panel wall system highly energy-efficient.
