Features :

• Fire‑resistant Performance: Rock‑wool core is non‑combustible material with melting temperature over 1000 ℃. It can effectively stop flame spread in fire accidents and minimize fire hazards.

• Energy‑saving & Thermal Insulation: Low thermal conductivity λ=0.043 W/(m·k), delivering excellent thermal insulation. Optimized joint design ensures good sealing and thermal‑insulating effect.

• Sound Insulation: Sound reduction ≥30 dB, effectively suppressing external noise interference.

• Water‑Tightness & Air‑Tightness: Unique interlocking joint between panels prevents water ingress. PU‑sealed panel ends maintain reliable air‑tightness.

• Robust & Durable: High‑quality rock‑wool core with high water‑repellency. Hard PU foam fills both sides of tongue‑and‑groove joints to boost overall structural strength for long‑term stability.

• Attractive Facade: Concealed fastener joint design, flat panel surface. Rich & long‑lasting PVDF coating colors.
