Product Features:
□ fire performance: rock wool core material is the non-combustible material, with ultra-high 1000 ° C sintering temperature, can effectively block the flame spreading, the maximum reduce damage in fire.
□ thermal insulation: rock wool thermal conductivity is low (λ = 0.043w / m · k), good insulation properties. Excellent node design to ensure sealing performance and thermal insulation.
□ sound insulation:  volume ≥ 30dB, effectively reduce the external noise interference.
□ Watertightness / airtightness: The board is designed as a unique chimeric node between the plates, preventing the intrusion of water; the connection joint of the board is sealed to maintain good air tightness.
□ rugged: high-quality rock wool material, high hydrophobic rate, last  for a long time.
□ Facial beauty: screw hidden node design, highly board flatness, rich color, wear well.
