1) With the same construction area,the practical area is big.
2)Characteristics:
n Fire-proof: the crystal water in plaster itself has the function of preventing fire and its fire-resistance time can reach 1.5 hours, so it is a fire-resistance material.
n Soundproof: The soundproof rate can reach 35db if the wall is made of paper plaster table.
n Anti-moist: Inside the plaster board, there are a lot of small holes which can automatically absorb and drain water according to the moist change in the environment and keep the home moist rate stable and the condition comfortable.
n Convenient Construction: The plaster board can be constructed easily by nailing, cutting and planning, and thus it becomes the first choice among home decoration materials.
