There are numerous varieties of gypsum board available on the market today. Among them, four types stand out as the most commonly used options: Plain Gypsum Board This type features an ivory-white core paired with gray paper. Known for being both cost-effective and widely accessible, it’s ideal for spaces that don’t require any special features. These boards work best in environments where the relative humidity stays below 65% continuously. Many people opt for the 9.5mm-thick version for ceilings or partitions due to its affordability. However, it’s worth noting that this thinner option isn’t as sturdy and tends to warp when exposed to moisture. For better durability, it's advisable to go for boards that are 12mm thick or more. Additionally, using thicker sheets can help reduce the likelihood of joints cracking over time. Water Resistant Gypsum Board This variant comes with a waterproofed core and paper facing. According to national standards, the surface and core of these boards must meet specific waterproofing criteria, with surface water absorption limited to no more than 160 grams and a maximum water absorption rate of 10%. Water-resistant gypsum board is well-suited for areas with higher humidity levels, such as bathrooms and toilets, where the relative humidity might reach up to 95%. Fire Resistant Gypsum Board These boards contain fire-retardant materials along with a significant amount of fiberglass. When cut, you’ll notice a lot of glass fibers protruding from the cross-section. High-quality fire-resistant gypsum boards typically incorporate non-alkaline glass fibers known for their excellent fire-retardant properties. Lower-end versions may use medium or high-alkaline glass instead. Mold Resistant Gypsum Board With enhanced surface moisture resistance, mold-resistant gypsum board has a surface water absorption rate of less than 160g/m². This makes it an excellent choice for ceilings, partition walls, and veneer walls in spaces prone to high levels of environmental dampness. Its ability to resist mold growth ensures longer-lasting performance in challenging conditions.
