What To Know About Rock Wool Insulation

By Bradd Alan


Naturally occurring minerals and rocks can be mined and processed to make long lasting insulation. This type of the insulation is referred to as rock wool insulation, which can also be referred to as slag wool, stone wool, or mineral wool insulation. The defining terms of the insulation depicts the raw materials from which it is made from.

There are many naturally occurring raw materials, which have different properties that a stone wool manufacturer can consider before choosing the inputs to include. Nevertheless, the most important feature of rock wool is its water absorption and heat resistance property. Based on where the insulation is to be installed, the major priority of the user will be based on the benefits the insulation offer such as noise reduction. The users will basically range from horticulturalists to industrial manufacturers.

In order to get the best rock wool insulation, the raw materials including the minerals and actual rocks are heated in a furnace. A lot of heat is supplied enough to melt the materials, at temperatures of as high as 1600C after which air or stream current is blown into the molten mixture. Advanced modern technological developments are nowadays facilitating the rotating of the molten raw materials at high speeds through a spinning wheel. This procedure can be compared to the way cotton candy is processed in manufacturing factories.

The entire process will produce a stone wool insulator that is made up of intertwined fiber that is bound together by strong starch molecules. Some oils are also added to the molten mixture to purify the insulator, by ensuring that no dust particle has been trapped within the final product. The careful process will result into an excellent heat conductor that can also be used to control how heat is supplied within a building. The insulators can serve best in such industries where heat monitoring is needed and where outbreak of fire could be more likely.

Mineral wool can be such an asset to both the manufacturer and the user in terms of the benefits it provides. The insulation is efficient in conserving energy consumption in holes or industries where they are applied in mass quantities. They are both economical and easy to produce or buy as locally produced materials are used. The World health Organization has also conducted extensive research to establish the suitability of the insulation. The organization has declared mineral wool a safe product for use, free from cancer and respiratory diseases causative agents.

The insulation is also adapted into retaining large amounts of water, a property that makes it water repellant. It will retain water as well as certain amounts of air making it to be the most reliable insulation in industries like hydroponics and horticulture. The ability to retain water has made it effective in supporting root growth and nutrients uptake in plants. However, the rock wool type of insulation may become hazardous especially when wet.

In order to lower the pH of the stone wool insulation in horticultural industries, a treatment has to be done. The insulation is soaked for 24 hours in pH-controlled water where the pH is lowered to neutral level. High ph value can hinder the absorption of minerals by plants.

In houses and offices, rock wool insulations will give users acoustic properties they need most. The insulation is a good sound absorbent that can make a noise free environment for effective communication. The wool and be incorporated with acoustic ceilings to offer permanent indoor noise insulators.
