Mineral wool is a popular material used for a number of different applications. Mineral wool is used for insulation, filtration, as a growing medium for seeds and for soundproofing. There are a number of benefits of using mineral wool insulation as a filter. The material is fairly cheap and makes it possible to remove sediment and foreign bodies from liquids.
What is Mineral Wool?
Mineral wools are also known as Mineral Fibers or Man Made Mineral Fibers. These are materials which are made using minerals and metal oxides, often using recycled elements from industrial processes.
Mineral wool is known as rock wool or stone wool. This is normally used in many homes as insulation. However it can also just as easily be used as a filtration material.
The most common use for mineral wool in homes is as insulation. While the individual fibers inside the mineral wool conduct heat well, a mat of them does not. A compressed mat of millions of fibers is a great insulator that prevents heat from escaping.
Fiberglass is also fire resistant, which makes it an ideal building material. This can stop the spread of fire and is required in many buildings. It can also be sprayed onto the surface of the walls as a form of fireproofing.
Another advantage of mineral wool is that it's not eaten by rodents. The only real problem with the material as an insulator is that if it becomes wet, it can become a breeding ground for bacteria and mold.
The R value of the insulation tells you how good the insulation is. The higher the R value of the insulation, the less thickness you will need to insulate your home. This is an important figure to consider because certain homes might have a limited amount of space available for insulation inside the walls. In this case, you will need to choose the highest R values available.
The densely packed mat of fibers also makes an ideal filter which can be used to filter a wide range of liquids. The individual fibers and the density of the insulation wll affect the size of the particles which are removed while filtering. In other words the higher the R value of the insulation you're using as a filter, the more particles it will be able to remove.
Also consider the R value when thinking about the liquid that you are filtering. If you are filtering something like water, then a high R value material will probably be suitable. However, filtering anything viscous like oil will require much lower R values to be effective. If the R value is too high for the liquid, then too much of it will be absorbed by the fiberglass.
You must also ensure that whatever you are filtering can not break down or dissolve the mineral wool. If it can, then it's not suitable.
The mineral wool can be cut to shape using a craft knife. This makes it very easy to use it to filter all sorts of different liquids.
