Aluminum sheets themselves do not directly affect indoor air quality. They are inert materials that do not emit volatile organic compounds (VOCs) or other harmful substances. However, the installation process might involve adhesives or sealants that could release VOCs temporarily. Proper ventilation during and after installation can mitigate this issue. Additionally, aluminum sheets can contribute to better air quality by enhancing thermal performance, reducing energy consumption for heating and cooling, and indirectly lowering emissions from power plants.
