Ivory core, gray paper, is the most economical and common variety. It is applicable to places of use without special requirements, and the continuous relative humidity of the place of use shall not exceed 65%. Because of the price, many people like to use 9.5mm thick ordinary paper faced gypsum board as ceiling or partition wall, but because the 9.5mm ordinary paper faced gypsum board is relatively thin and low strength, it is easy to deform under wet conditions, so it is recommended to choose more than 12mm gypsum board. At the same time, the use of thicker plates is also an effective means to prevent joint cracking

water resistant gypsum board

its core and protective paper have undergone waterproof treatment. According to the requirements of the national standard, the paper surface and core of water resistant gypsum board must meet certain waterproof requirements (the surface water absorption is not more than 160g, and the water absorption is not more than 10%). Water resistant paper faced gypsum board is suitable for places where the continuous relative humidity does not exceed 95%, such as toilets, bathrooms, etc
