The noise of passing cars, screams, loud conversations of neighbors, crying children, the sounds of a working elevator – all this can spoil the mood of even the most patient person. Scientists have proven that constant background noise causes significant harm to our health. Irritability, insomnia, or nervous breakdowns are not the worst consequences of noise pollution. Scientists estimate that 61 thousand person-years are lost annually in Europe alone due to heart disease caused by noise. If you do not want to become part of these statistics and want to get rid of extraneous sounds in the apartment, then the only way to do this is to soundproof your home.
Noise in the apartment: how to get rid of it?
Everyone knows that in the “Khrushchevs” you can hear the conversation of neighbors living several floors above. But this is also found in modern homes.
In monolithic buildings, sound is transmitted through the vibration of walls and ceilings, cracks, crevices and gaps in the structure. Therefore, it is advisable to think about sound insulation before you start repairs.
Sounds enter our homes in many different ways. There are several types of noise:
- a drill drilling a wall, falling objects, steps coming from above, moving furniture – this is a manifestation of impact noise;
- barking of a dog, crying of a child, music from neighbors, loud conversations – this is airborne noise.
The sounds of the first category penetrate through the vibration of the structures of the house, the second ones are heard through cracks and cracks.
Before choosing a sound insulating material, you need to decide which of the noise you will eliminate.
In both cases, soundproofing stone wool slabs are the best choice.
Stone wool for noise insulation
The market for soundproofing materials offers a wide range of products. But many of them take up a lot of space and are short-lived. Some of the materials are undesirable to use in residential buildings due to their non-environmental friendliness. So, widely advertised polymer materials can resonate with sound, which only amplifies the noise.
The best performance in terms of sound absorption is demonstrated by mineral wool: both glass and stone. But glass wool absorbs moisture, as a result of which it loses its positive qualities. This does not happen with stone (or basalt) wool. The material has low hygroscopicity, and its sound-absorbing properties are not lost for many years.
Properties and characteristics
Rock mineral wool is an inorganic fibrous material, raw materials for which are various rocks: basalt, gabbro, diabase.
In English it is literally called “mountain wool”. Indeed, the material looks like matted wool fibers. The material production technology imitates a natural process: crushed stone at a temperature of 1500 ° C melts in a furnace to a liquid state. Then the finest fibers are formed in the centrifuge under the influence of air currents. The individual fibers are connected with a special binder, to which a water repellent is added for moisture resistance. And only after heat treatment the resulting “carpet” is cut into pieces and packed.
Thanks to this base, the mineral wool has excellent operational and strength characteristics:
- reliable sound and heat insulation;
- water-repellent properties;
- tensile strength;
- resistance to chemically active substances.
Rodents are not afraid of rock mineral wool, fungi and bacteria do not appear on it. Ultraviolet rays, temperature drops do not affect it.
Cotton wool is not able to absorb moisture. In this case, steam passes through it without any obstacles – this is a very important property. Due to its good vapor permeability, excess moisture and condensation evaporate and are removed from surfaces for which they are harmful.
All these qualities are used by manufacturers in the manufacture of stone wool slabs.
Why choose stone wool for sound insulation?
Stone wool is an ideal soundproofing material. We list 7 facts confirming such a statement.
Rock mineral wool fights all kinds of noise. The randomly placed fibers absorb vibration generated by impact noise. In addition, they dampen the airborne noise waves.
You can use this material for soundproofing any surfaces of a living space. ROCKWOOL manufactures a wide range of noise insulation materials:
- FLOR BATTS Plates for soundproofing floors.
- ACOUSTIC BATTS Noise insulation of walls with high performance (sounds are damped up to 63 dB).
- ROCKWOOL ACOUSTIC Plates used for soundproofing partitions and interfloor floors. Thanks to compression, packaging of ACOUSTIC STANDARD boards is very compact and convenient.
- Acoustic ULTRA THIN These are the thinnest soundproofing boards (only 27 mm) used for wall and ceiling installation.
Each of the products has its own characteristics, which you can familiarize yourself with by going to company directory.
With the help of slabs from this manufacturer, you can ensure sound insulation of an apartment or house.
Having made soundproofing with stone wool, you can forget about it for a long time. It will last at least 50 years.
The same qualities of basalt wool, which are used for sound absorption, give the material the properties of an excellent insulation.
Rock mineral wool does not collapse at temperatures up to 1000 degrees. It not only does not burn, but also does not allow the fire to spread.
The size and design of the slabs allows for installation by yourself. In order to create a good sound absorption system, you do not have to go to a construction company and spend extra money.
The material is absolutely environmentally friendly, it can be used in any living space, including soundproofing children’s rooms.
The environmental friendliness and absolute safety of stone wool confirm the conclusions of the researchers:
- All ROCKWOOL factories operating in Russia have received the EcoMaterial Absolute certificate. This is one of the highest marks confirming the environmental friendliness of the materials produced.
- The EcoMaterial Absolute label confirms that the products meet environmental and safety requirements and are recommended for use in hospitals, sanatoriums, residential bedrooms and children’s rooms.
