Yes, ceramic fiber insulation can be used in residential buildings. It is known for its high-temperature resistance, thermal insulation, and sound absorption properties. However, it's important to note that ceramic fiber insulation is categorized into different types based on their bio-persistence, which affects their safety for use in residential settings. Low bio-persistent types are generally considered safe for residential use, while high bio-persistent types may pose health risks and are less suitable. It's crucial to adhere to safety guidelines and regulations when installing ceramic fiber insulation to ensure the health and safety of occupants.
