Ceramic fibers can affect air quality in a building in several ways. They are known to be lightweight, heat-resistant, and have excellent thermal insulation properties, which can improve energy efficiency and reduce heating and cooling costs. However, if these fibers are released into the air, they can become airborne particles that may be inhaled, potentially causing respiratory issues. It's crucial to ensure proper handling and containment of ceramic fibers to prevent their release into the indoor environment. Additionally, the use of ceramic fibers in buildings should comply with safety regulations to minimize health risks and maintain good air quality.
