What’s Rockwool Insulation?

Stone wool insulation is made from rocks and minerals and is used in construction, industry, and automotive applications. It is made by heating raw materials in a furnace or spinning molten rock. Stone wool is a good heat and sound blocker and is safe to use. It can hold water and air, making it a popular growing medium in horticulture and hydroponics. However, it must be treated to lower its pH before use.

Stone wool insulation refers to a type of insulation made from actual rocks and minerals. It also goes by the name of rock wool insulation, mineral wool insulation, or mineral wool insulation. A wide variety of products can be made from stone wool, due to its excellent sound and heat blocking ability. This type of insulation is commonly used in building construction, industrial plants and automotive applications.

To make stone wool insulation, minerals and other raw materials are heated to about 2910°F (about 1600°C) in a furnace, through which a stream of air or steam is blown. More advanced manufacturing techniques rely on spinning molten rock at high speed in a spinning wheel, somewhat similar to the way cotton candy is made. The finished product is a mass of very fine woven fibers bound together with starch. Oil is also added during production to reduce dust formation.

The individual fibers of stone wool insulation are themselves good conductors of heat, but the rolls and sheets of this insulation are highly efficient at blocking heat transfer. They are often used to prevent the spread of fire in buildings, due to their extremely high melting point. As with other types of insulation, stone wool can play an important role in reducing energy use in homes and businesses. Made from natural materials, stone wool insulation is safe to produce and use, if the proper guidelines are followed. Decades of research has shown that it poses little or no health risk to humans, including that of respiratory and other cancers.

While unappealing to rodents, stonewool can pose problems in other ways, especially if left to get wet. Rockwool insulation is capable of holding a large amount of water, although gravity will cause it to drain slowly, as long as it has an escape route. This ability to hold water, coupled with the fact that it holds a certain amount of air at all times, has made stonewool a popular growing medium in horticulture and hydroponics. These properties of stone wool allow for good root growth and nutrient uptake. It also provides a good mechanical structure to the plant, keeping it strong and stable.

In its natural state, stone wool has a relatively high pH, ​​which is not conducive to plant growth. In order for it to be suitable as a medium for plant growth, it must be treated to lower the pH to a more stable, neutral value which will allow the plant to thrive. This treatment involves soaking the stone wool in pH adjusted water for at least 24 hours before use.
