Rock Wool Sandwich Panel
Rock Wool Sandwich Panels are high-performance building materials consisting of two metal sheets (galvanized steel/aluminum) bonded to a rock wool core.

Offering excellent fire resistance (non-combustible, A1 class), they provide superior thermal insulation and sound absorption. With strong structural stability and moisture resistance, these panels are ideal for walls, roofs, and partitions in industrial buildings, commercial facilities, and public constructions.

Rock Wool Sandwich Panels: Your Trusted Choice for Fire-Safe, High-Performance Construction

1. Product Overview: Strength Meets Safety

Our Rock Wool Sandwich Panels are engineered for durability, fire resistance, and all-around performance—perfect for projects where safety and efficiency can’t be compromised. Each panel features two high-quality metal facings (galvanized steel or aluminum, corrosion-resistant coated) bonded firmly to a dense, non-combustible rock wool core via industrial-grade adhesive. This three-layer structure balances lightweight handling with robust structural support, making it a top pick for modern construction.

2. Core Advantages: Why Choose Rock Wool Sandwich Panels?

A1-Class Fire Resistance (Non-Combustible)
The natural rock wool core is inherently fireproof (meets A1 fire rating standards), resisting high temperatures up to 1000°C. It won’t melt, release toxic fumes, or spread flames—critical for industrial, commercial, and public buildings where fire safety is mandatory.

Superior Thermal & Acoustic Insulation

  • Thermal Insulation: Low thermal conductivity (λ=0.038-0.042 W/m·K) reduces heat transfer, cutting heating/cooling costs year-round.
  • Sound Absorption: Dense rock wool structure absorbs noise (25-35 dB sound reduction), ideal for factories, workshops, or busy commercial spaces.

All-Weather Durability
Metal facings with anti-rust, anti-UV coatings withstand rain, snow, humidity, and extreme temperatures (-30°C to +80°C). The rock wool core is moisture-resistant (no mold growth) for long-term reliability.

Easy & Fast Installation
Lightweight design (20-35 kg/m²) and interlocking edges allow quick on-site assembly, reducing labor time and project costs compared to traditional building materials.
