Core Difference Comparison
Raw Materials and Production Process
Gypsum board: Made from building gypsum powder as the core raw material, fiber reinforcements (such as glass fiber) are added through a mixing, pressing, and drying process.
1. Fibercement board: Made from cement as the base material, with mineral fibers (such as asbestos, glass fiber) or plant fibers (such as paper pulp) added through pulping, molding, and autoclaving.
2. Physical Property Comparison
Waterproofness: Fibercement board can withstand long-term exposure to high humidity without deformation, and its water absorption rate is less than 0.5%. Gypsum board softens easily when exposed to water and is only suitable for dry areas.
3 Load-bearing Capacity: The screw grip strength of 12.5mm thick fibercement board reaches 600 N/mm², while that of gypsum board is only 100 N/mm². Fibercement board can directly hang heavy objects.
4 Fire Rating: Both are Class A non-combustible materials, but fibercement board offers superior structural stability under sustained high temperatures.
5 Sound and Heat Insulation: Fibercement board has a higher density (1.2-2.0 g/cm³), improving sound insulation by approximately 30% compared to gypsum board.
6 Differences in Application Scenarios.
Gypsum Board:
Indoor ceilings and partitions in dry areas.
Preparing the base before applying latex paint.
Decorative surfaces requiring intricate shapes.
7 Fibercement Board:
Wet environments such as bathrooms and kitchens.
Exterior wall enclosures and loft flooring.
Locations with high fire and sound insulation requirements (such as computer rooms and theaters).
8 Economic and Construction Considerations
Cost Comparison
Gypsum board costs approximately 10-30 yuan/㎡, while fibercement board costs approximately 20-60 yuan/㎡ (for the same thickness). However, fibercement board requires less moisture-proofing treatment.
9 Construction Characteristics
Gypsum board can be directly puttyed and painted, while fibercement board requires specialized cutting tools and a waterproofing treatment.
