It can tolerate mold, fire, and water, among other characteristics that make it a valuable and durable building material. Additionally, it does not release harmful chemicals when fire comes into contact with its fibers. Stone wool appears to be more sound-absorbing and thermally insulating than regular fiberglass, which is even better. It is a multipurpose repellant made from one of the most common minerals on earth. Stone wool may considerably delay the spread of flames inside building walls in terms of fire resistance, and in an emergency, every second matters. Stone wool insulation is non-combustible and resistant to heat up to 1,177 degrees Celsius.
Slag wool insulation is primarily formed of fibers created by melting blast furnace slag, the main component, with a variety of natural rock and binders, depending on the product. Blast furnace slag makes up around 70% of slag wool insulation, with natural stone making up the rest of the raw materials. The ability of slag wool insulation to increase a building's energy efficiency is one of its most significant environmental advantages. A thermally efficient structure reduces the energy needed to maintain a comfortable indoor atmosphere. Less energy reduces air pollution and greenhouse gas emissions like CO2 and NOx and helps conserve the supply of non-renewable fuels. A Harvard University of Public Health study found that public health benefits and lives were saved from the emissions reduction caused by energy efficiency and the usage of thermal insulation.
