Product Introduction

What is sandwich panels?
A sandwich panel is any structure made of three layers: a low-density core (PIR, mineral wool, EPS), and a thin skin-layer bonded to each side. Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required.
Leveraging unique core material properties, it delivers excellent fire resistance, thermal insulation, and acoustic absorption68. Three core options available: pure rock wool, PU edges rock wool, and PU edges fiberglass.
Product Advantage
☆Fire Performance
Rock wool core (non-combustible) withstands >1000°C melting point, effectively blocking flame spread and minimizing fire damage.
☆Thermal Insulation & Energy Efficiency
Low thermal conductivity (rock wool: 0.043 W/(m·K)) paired with precision joint design ensures optimal sealing and insulation.
☆
Acoustic Insulation
Sound reduction ≥30 dB, significantly reducing external noise interference.
☆
Water/Air Tightness
• PU edges prevent water penetration.
• Sealed connections maintain superior air tightness.
☆
Structural Durability
High-quality rock wool or fiberglass core with high hydrophobicity ensures long-term stability.
☆
Aesthetic Quality
• Hidden screw joints enable seamless flat surfaces
• Baking paint coating offers rich colors and lasting finish.
