Calcium silicate board and cement board are two commonly used boards in construction. When selecting, their performance, cost, and application scenarios need to be comprehensively evaluated based on specific needs.
1. Comparison of material characteristics
Calcium silicate board: made from siliceous and calcareous materials and reinforcing fibers through high temperature and high pressure. The characteristics are lightweight (low density), high strength, excellent fire resistance (A1 level non combustible), moisture and mold resistance, and easy cutting and processing. But the impact resistance is slightly weaker, and the price is usually higher than that of cement boards.
Cement board: Using cement as the base material and adding fiber reinforcement. The characteristics are high hardness, strong compressive and impact resistance, low cost, but heavy weight (inconvenient for construction and handling), easy to warp and crack in long-term humid environments, and slightly inferior fire resistance to calcium silicate board (usually A2 grade).
2. Application scenario selection
Indoor environment: Calcium silicate board is preferred. Suitable for areas such as suspended ceilings, lightweight partitions, bathrooms, etc., due to its excellent moisture resistance and ease of construction. Calcium silicate board is more recommended for places with high fire prevention requirements, such as kitchens and computer rooms.
Outdoor or high load scenarios: Optional cement board. Suitable for load-bearing or exposed areas such as exterior wall panels, canopies, and ground cushions, but their surfaces require waterproof coating treatment to prevent cracking.
Moist environment: Calcium silicate board has better mold resistance, and it is recommended to use it in long-term humid areas (such as basements); Cement boards need to be equipped with waterproof technology.
3. Cost and construction considerations
The unit price of cement board is low, but its large weight may increase transportation and installation costs (such as the need to reinforce the keel). Although calcium silicate board has a high material cost, it is lightweight and easy to cut, which can save labor and time.
If long-term durability is pursued (such as in commercial spaces), the maintenance cost of calcium silicate board is lower; Temporary buildings or projects with limited budgets may consider using cement boards.
4. Environmental Protection and Safety
Both are inorganic materials, but it should be noted that some cement boards may contain asbestos (choose asbestos free products). Calcium silicate board has better environmental friendliness and no formaldehyde emission.
Summary: Calcium silicate board is preferred for indoor decoration and fire and moisture prevention scenarios; For outdoor load-bearing and low-cost projects, cement boards can be considered, but moisture-proof treatment should be done well. Suggest making a comprehensive decision based on functional requirements, budget, and construction conditions.
