Product Advantage

☆A1 Fireproof Rating
Achieves the highest European fire resistance classification (A2-s1, d0), making it completely non-combustible. Ideal for enhancing building safety and compliance in high-risk environments.

☆Superior Thermal Insulation
The tightly sealed PU and rockwool core work synergistically to minimize heat transfer, significantly reducing energy costs for heating and cooling in all climates.

☆Excellent Acoustic Performance
The dense, fibrous rockwool core effectively absorbs sound waves, providing outstanding noise reduction. This creates quieter, more productive environments for factories, offices, and residential buildings.

☆Durable & Structural Integrity
The rigid PU sealing bonds the metal facings to the core, creating a exceptionally strong, lightweight panel resistant to moisture, corrosion, and deformation, ensuring long-term performance.

Product Application

These sandwich panels are extensively used in the construction of industrial warehouses, manufacturing plants, cold storage facilities, clean rooms, and commercial buildings where superior fire safety, thermal efficiency, and structural durability are critical requirements. They are also ideal for fire-rated partitions and walls.
