Steam Traps

Similar to fiberglass, mineral wool boards and blankets have acoustic applications as well as thermal. While mineral wool is widely used in Europe, the world leader in this material, Roxul, has opened its first plant in the US in nearby Marshall County, Mississippi in 2014. Mineral wool insulation is denser than traditional insulations. This effectively reduces air flow and sound transmissions. Higher air flow resistivity means better sound attenuation. Besides being sound absorbing, this material is also fire resistant, water repellent and easy to fabricate.
