Guide to Electrical Wire Insulation: Why It Is Important. Safety. Electrical wire insulation is essential to keep an area safe and help individuals avoid electric shock. The Occupational Safety and Health Administration (OSHA) considers exposed wires, worn insulation and removed insulation as electrical hazards. In wet conditions, from bathrooms to rain, the risk of shock increases.
Is Insulation Mold Resistant? (Explained and Helpful Guide)Fiberglass and stone wool have the highest mold and mildew resistance properties among the most commonly used home insulation materials. Fiberglass excels at resisting mold because it contains significantly reduced glass shards. Being inorganic, glass doesn’t support the growth of mold. Mold is fungus, needing food, oxygen, and water to grow.
