What is stone wool insulation?

What is stone wool insulation?

Stone wool and slag has a very low heating transfer coefficient and its insulation power is 23 times more than concrete wall and 22 times more than brick wall.

Stone wool

The temperature tolerance of Thermal and acoustic insulation is +750 ° C and its melting point is 1300 and its cold tolerance is also -30 ° C, Stone wool and slag has a very low heating transfer coefficient and its insulation power is 23 times more than concrete wall and 22 times more than brick wall.

Usage

Stone wool and slag is produced in types of Isotherm (bulk raw wool), ISO blanket (blanket), ISO pipe (pipe), phono panel (compressed board) and phono felt (quilt) and it has various usages, including refinery industries, power plant industries, food industries, building and facilities and even hydroponic greenhouses (a bed for soilless culture).

To reduce the high cost of energy, using of thermal insulations is necessary when using of buildings, although using of this insulation may somewhat increase the construction cost and cost price but we will find that this action will save costs in long term with a forward-looking.

Saving energy by thermal insulation is also beneficial for the environment. The stone wool as thermal insulation by reducing required energy for heating or cooling buildings, prevents more carbon dioxide emission from power generation plants. Stone wool thermal insulation (Rock Wool) consists of mineral fibers, for this reason it is sometimes referred as Mineral Wool. Raw ingredients to produce this insulation is Basalt rock. Basalt rock is among igneous rocks that is result of volcanic activities and there is in our country in abundance.

The feature of stone wool insulation

The most important feature of stone wool is its high resistance to fire. Stone wool does not burn, so you can use it as protective material to fire. Most of countries consider special discounts for insuring the buildings that they are insulated by stone wool.

The stone wool insulation is an inappropriate environment for the growth of pest, fungi, bacteria and vermin insects and it is safe as an inorganic material against these parasites. The stone wool is most harmless insulation among types of insulations that are made in the world to this day and it is completely environment-efficient.

Unlike other thermal insulations in this group, the stone wool does not damage the skin and it also does not cause the skin irritated. It has compatibility with all materials that are used in the building and industries, and impact of this insulation with these materials does not make a problem.

Advantages of stone wool

Stone wool thermal insulation is manufactured in the country as a material with specific and standard features.

Stone wool does not decomposed and corrupted by other chemical materials or microorganisms.

Root aeration in stone wool is done well.

The plants are less affected by temporary drought because of stone wool’s keeping enough moisture.

Stone wool is a material free of pollutant factors, and is lightweight and sterile.

Performance against fire

Resistance to fire is among important features of stone wool insulation. Stone wool thermal insulation is known as a protector against fire because it is not flammable and does not flare. When fire happens, the metal structures (absorbing high heating and becoming hot), loses its mechanical resistance and whole structure collapses; so stone wool insulation is used for insulation of metal structures (columns and beams of the building are insulated by stone wool in proper methods) and no problem is made for the structure even up to ten hours in case of fire continued.

Acoustic features

Stone wool insulation has also acoustic features (by reducing sound transmission and sound absorption). Stone wool insulation has high efficiency in sound absorption and reduction and the stone wool is used in sound studios, airports, under the rails and in metro stations inside the city in order to prevent the transmission of vibrations and sound. Recent experiments reflect this point that we can reach to sound reduction to target level (by designing and installing insulations and also by putting a proper air gap on the back of sound insulation), and we can enhance its insulation absorption coefficient increasingly. Stone wool and its usage in the building wall:

Phono panel or board stone wool is a very proper insulation for the walls of the buildings.

This product is a very proper sound and thermal insulation. You can easily prevent energy wasting up to 95% in the building by using of stone wool, in fact this production is also a very strong sound insulation. The problem that today is poor in almost more than half of the high quality buildings is that residents of a housing complex often complain about sounds around the building. These sounds include the sounds of adjacent neighbor or sound of the street or sound of the highway near of the residence place.

You can easily solve the above problem only by using of board stone wool with 50 mm thickness and a density between 50 to 100 kilogram/cubic meter which is often used of 80 density.

 Of course the best model for installation the stone wool is exactly between two wall blocks that it should use during the building construction.

For office buildings, usually it is used of 50 mm thickness and 100 kilogram/cubic meter density.

This action, especially in large buildings or hotels and places with large space causes energy consumption highly reduced and it is actually a long-term investment for homeowners and of course is a help to environment.

For example, in the case of without insulation, a radiator fin is considered for each square meter for the building’s heating system, that if the insulation is done properly, a radiator fine is required for each 3 square meters that it reduces to a third the heating system cost in the first step and of course the energy consumption becomes a third in long-term and for always.

Recyclability

This production has a recyclability to the ecosystem because of being mineral of raw materials.

Nano researches

We can refer to the feature of resistance to powdering, increasing the recyclability strength and water non absorption by using of silicon emulsions water to making hydrophobic and making anti-dust by chemical formula of Oligo dimethyl hydro siloxane.
