What To Know About Rock Wool Insulation

By Bradd Alan


Basically, the term rock wool insulation stands for a type of insulation that has been developed from the actual rocks and minerals as mined from the ground. There are other terms referring to this material such as slag wool insulation, stone wool insulation and mineral wool insulation.

Important to note is that there are many products that can be manufactured from Rockwool. This is because the mineral wool possesses exceptional property of holding block sound and extreme heat. For this reason, the insulation is generally employed in a number of plants from automotive application plants to building and construction plants.

The other basic guideline a manufacturer or glass wool user should know is how the insulations are made. The manufacture involves heating of the raw materials in extreme furnace temperatures of about 1600C. This is done to melt the metal and mineral ores where air current is supplied to cool the molten rock wool. A spinning wheel can also be used to rotate the molten rocks at high speeds for effective processing as done in other production companies such as cotton manufacturers.

The final product can be defined as a mass of finely intertwined fibers that have been bound together with starch. The processing will also feature addition of oil, which helps in decreasing the formation of dust in the rock wool product. Therefore, the process enables the individual fibers of rock wool insulation to be good conductors of heat on their own. The rolls and the sheets of this insulation are also highly efficient especially at blocking heat transfer. They are therefore used to curb fire spreading in buildings, as they do not melt easily.

The other features of the rook wool insulators is that they consume less energy and can enable the user to make huge savings on energy costs. They are also cheap to buy and make as they employ the locally available materials that are very durable. Furthermore, the rock wool insulation is free from cancer or respiratory causing pathogens. This has already been proved by a research by the World Health Organization.

Mineral wool is also a perfect insulator for absorbing excess water, which make it a desired water repellant. The insulation can absorb large quantities of both air and water simultaneously and can be very effective for use in horticultural and hydroponic companies. In horticulture, the rock wool will enhance root development of vegetables and fruits and facilitate absorption of nutrients in plants. Research is being conducted to establish whether the insulation could prove to be disastrous especially when extremely wet.

Rockwool is naturally basic and therefore would not be supportive for crop production industries. Therefore, a treatment to lower the pH must be done to achieve a neutral environment that favors growth. Soaking in pH-adjusted water for a number of days can help treat the basic rock wool to become neutral. The result makes the insulation a favorite environment for horticultural crops, keeping the roots strong and stable.

Rock wool insulation can provide a good acoustic comfort as it acts as a noise absorbent. Noise is known to affect people and interfere with communication at different levels. The insulation is a porous open structure that absorbs sound and reduces noise vibrations. It can be coupled with acoustic ceiling to provide better solutions for indoor acoustics. This works better in homes or workplaces to offer long life solution to noise reduction.
