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.
Product Advantage
☆Fire Performance
Polyurethane is a Class B fireproof material that effectively minimizes fire damage.
☆
Thermal Insulation & Energy Efficiency
• Thermal conductivity ranges from 0.019 to 0.023 W/(m·K), making it an exceptional insulating material.
• Advanced joint design ensures both sealing performance and insulation effectiveness.
☆
Acoustic Insulation
Excellent sound insulation significantly reduces external noise interference.
☆
Water/Air Tightness
