Long-life

The board is long-life: More than 50years cement product, high temperature and high pressure steaming.

The color is long-life: the color do not change even after being roasted under high temperature for 6-12 years.

The wall is long-life: board and wall have clearance, which can breathing and airing.

The fixing is long-life: fasten with rust prevention steel nail.

Heat preservation

Heatproof performance: Excellent

Energy saving effect: activity ratio of air-condition=1/3~1/5 before being assembled

Watertight

Horizontal folded corner buckled, vertical silicon sealant sealing up

Environment-friendly

No asbestos, inorganic material and innocuity

Speediness, Laborsaving

Normative technology, simple tool, easy operation, quick installation.
