While it is technically possible to use black fiberglass scraps to create a flooring system, it is not recommended for a home. Fiberglass scraps can be brittle and may not provide the structural integrity needed for a safe and durable floor. Additionally, they may not be comfortable underfoot and could pose a risk of injury due to sharp edges. Professional flooring materials are designed for residential use and offer better performance, safety, and comfort. It's best to use materials specifically intended for flooring to ensure the longevity and safety of your home's flooring system.
