Man-made glass fibers, such as rock wool and slag wool, have been widely used in insulation and soundproofing applications across Europe and North America for many decades. Over the years, extensive research has been conducted to assess whether the fibers released during production or demolition pose a cancer risk when inhaled. Recent epidemiological studies over the past 15 years, following the last IARC evaluation, indicate that there is no evidence linking these fibers to an increased risk of lung cancer or skin tumors in workers exposed during manufacturing processes. Similar findings have been observed for other types of cancer. In addition, the industry has invested heavily in developing new materials that offer comparable thermal and acoustic insulation properties but break down more quickly within the human body. Asbestos, known to be a potent carcinogen, was once widely used as an insulating material due to its durability. However, it is now recognized as a major health hazard, causing mesothelioma and lung cancer. Unlike asbestos, which degrades very slowly and remains in the body for long periods, newer materials are designed with better biodegradability in mind. The Task Force has determined that only substances with high biodegradability are classified as possibly carcinogenic to humans (IARC Class 2B). These include durable ceramic fibers used in high-temperature industrial settings and specialized glass wools not intended for general insulation. On the other hand, commonly used glass fiber products like mineral wool, rock wool, and glass wool are now categorized as potentially carcinogenic. Continuous glass fibers, often used to reinforce plastics, are considered non-carcinogenic. However, they can still irritate the respiratory system and skin, so their use should be limited to industrial environments with proper containment and safety measures. Scientific studies confirm that all types of artificial glass fibers, including continuous glass fiber, rock wool, and glass wool, do not cause cancer. This clarification resolves a long-standing concern within the insulation and soundproofing industries, helping to promote safer and more informed usage of these materials. With this understanding, the industry can continue to grow while ensuring the health and safety of workers and end-users alike.
