Insulation:
Core materials (e.g., rock wool with λ=0.043W/(m·K)) reduce heat transfer, cutting energy costs.


Fire Resistance:
Non-combustible cores ensure high fire ratings (e.g., 50mm - REl 30, 80mm - REI 60).

Waterproof:
Special design and surface treatment prevent leakage and extend lifespan.

Strength:
Integrated structure withstands heavy loads, allowing larger purin spacing.

Soundproof:
Reduces noise; rock wool cores achieve RW=29 - 30 dB.

Easy Install:
Lightweight, pre-cut panels speed up installation (600-800m?/day).

Aesthetic:
Customizable colors and sleek design enhance building appearance.

Protection:
Surface film guards against scratches during transit.
