What is Rockwool Sandwich Panel? The Ultimate Guide for Modern Construction
What is it Made of? (The "Sandwich" Structure)
Outer Layers: High-quality color-coated steel sheets (PPGI/PPGL).
Core Material: High-density mineral wool fibers (Stone wool).
The Bonding: Professional structural adhesive for zero delamination.
Key Features that Solve Your Pain Points
A-Grade Fire Resistance: Non-combustible core (melting point > 1000°C), meeting strict safety codes for developers.
Thermal Insulation & Energy Saving: How it reduces HVAC costs in industrial buildings.
Superior Sound Absorption: Ideal for noisy factory environments or highway barriers.
Technical Specifications (Product Parameters)
To help you choose the right material for your project, here are the standard technical specifications for Shanghe Rockwool Sandwich Panels:
Parameter Specification Details Core Material High-density Water-repellent Rockwool (Mineral Wool) Rockwool Density 80kg/m³ - 150kg/m³ (Customizable) Steel Plate Thickness 0.4mm - 0.8mm (PPGI/PPGL/Stainless Steel) Panel Thickness 50mm / 75mm / 100mm / 150mm / 200mm Effective Width Wall Panel: 950mm / 1000mm / 1150mm; Roof Panel: 960mm / 1000mm Fire Rating Class A (Non-combustible) Thermal Conductivity ≤0.044W/(m·k) Certifications CE, ISO9001, SGS
Why Contractors Prefer Rockwool Panels for Rapid Construction?
Easy Installation: Interlocking tongue and groove system.
Lightweight yet Durable: Reduces the load on the building's main structure while maintaining high compressive strength.
Applications: Where to Use Them?
Industrial warehouses and cold storage.
Cleanrooms (Pharmaceutical & Electronics).
Prefabricated houses and temporary site offices.
How to Choose a Reliable Manufacturer in China?
Look for Certifications: Mention CE, ISO, and SGS (Shanghe’s strengths).
Density Matters: Explain that 100-120kg/m³ is the standard for high-quality insulation.
