Corrugated Bituminous Waterproofing Board is made of wood fiber impregnated with asphalt, pressed under high temperature and pressure. It features high mechanical strength, impact resistance, compression resistance and light weight. Properly installed, it can resist typhoons up to 200km/h (Level 12).

It is widely used for large roofs and low-slope roofs. The corrugated structure allows air convection and exhaust through the ridge, creating a "chimney effect" to achieve ventilation, heat dissipation and dryness of the roof. It also improves the freeze-thaw resistance and service life of roof tiles.

The board is recyclable, easy to install, and saves labor, materials and time.

It is suitable for warehouses, factories, villas, public buildings and other sloped roof systems requiring long-term waterproofing and ventilation.
