Yes, ceramic fiber products can be used in high-rise buildings and large-scale commercial buildings. They are valued for their high-temperature resistance, thermal insulation, and fireproofing capabilities. These properties make them ideal for applications such as fire barriers, insulation in walls and ceilings, and heat protection in HVAC systems. Their lightweight nature also contributes to reduced structural load, which is beneficial in tall structures. However, it's crucial to ensure they meet specific building codes and safety standards for each application.
