The use of black fiberglass tissue in commercial buildings can affect indoor air quality in various ways. Black fiberglass, when used as insulation, can help reduce energy consumption and maintain a comfortable temperature, but it may also release fibers into the air. These fibers, if inhaled, can cause respiratory issues and are potentially harmful to health. However, modern manufacturing processes have improved to minimize fiber release, and when properly installed and contained, black fiberglass tissue poses minimal risk to indoor air quality. It's crucial to follow safety guidelines and ensure proper ventilation to maintain good air quality.
