Rock wool/polyurethane core material is non-combustible material, with a sintering temperature of more than 1000 ℃, which can effectively block the spread of flame in the fire and minimize the fire.

Rock wool thermal conductivity is low (λ = 0.043 w/m-k), ensuring good thermal insulation performance. Excellent node design guarantees sealing performance and heat preservation effect.

Sound insulation ≥ 30dB, effectively reducing the interference of external noise.

The unique mosaic node between the boards prevents the intrusion of water. The end connection of the board is closed inside to maintain excellent air tightness.

Screw hidden node design, high flatness of the board surface, rich paint coating color, lasting color.

There are 12 versions of seam lap, seamless lap, Lishui corrugated, flat mirror, rock wool core material, glass wool core material, pure polyurethane core material, etc.
