Surround yourself with silence and tranquility is a dream of each of us. True, there is so much noise around that it is becoming increasingly difficult to protect your home and your family from it. To forget about the annoying noise coming from the street or from the neighbors above, soundproofing materials help. They are presented in a huge variety, so there is plenty to choose from.
What's the noise?
Specialists divide it into two types - structural and air. The first appears due, for example, to falling something on the floor or rearranging the furniture in the room. The second is spread through the air, for example, it can be the noise of a radio or talking on the phone. In order to stay indoors was comfortable, it is important to reduce the level of sound waves. And for this you need to get rid of noise or prevent them from entering the room. Modern soundproofing materials allow you to limit the flow of noise into a house or apartment at the construction stage.
How to isolate noise?
There are several ways to get rid of noise in the construction process. The first is the installation of interior partitions and walls. Second -installation of additional flooring when the joints are tightly sealed. The third is to reduce the number of windows and doors. And the fourth way is to hide engineering communications that conduct noise well. For example, using soundproofing materials for walls, you can create a kind of barrier to the path of a sound wave, as well as contribute to its absorption and dispersion.
Sound absorption is the number one goal
Sound-proofing materials for an apartment can be chosen and those that will absorb sounds. They are made on the basis of synthetic raw materials or natural fibers. Such materials:
- off;
- pass steam well;
- eco-friendly.
You can also use ready-made solutions to save rooms from noise. We are talking about structures that are initially created as noise-absorbing. This group includes sandwich panels or vibroacoustic panels.
What to consider?
The modern market offers a huge number of solutions to achieve sound insulation. For example, you can choose materials that will isolate impact noise. The most popular in this group are lightweight foam materials in the form of rolls or sheets. They are based on such raw materials as melamine, rubber, polyethylene, polyurethane. Such soundproofing materials for the home are good for isolating impact sound, for example, when installing a leveling screed or flooring. True, the noise isolation rate that is transmitted through the air is not very high,therefore, in order to get rid of everyday sounds, they should not be used. Foam materials are also good as a vibration-absorbing pad. The porous structure precludes their use for cladding. Fiberglass and natural cork are also lightweight and easy to install – they can be used as a gasket in multi-layer constructions.
Variety of materials
Most often, glass wool is used to provide sound insulation, which is durable, resilient and vibration resistant. The voids in it are filled with air, so the sound absorption is of high quality. In addition, glass wool shows resistance to moisture, is light in weight and has sufficient elasticity.
Based on metallurgical alloys, noise-insulating materials such as mineral wool are created. The fibers in it are arranged in a chaotic manner, so sound absorption is good. In addition, cotton wool does not burn, has a breathable structure and is easy to cut.
Good for soundproofing and sandwich panel, which include gypsum fiber and mineral wool. However, they are quite thick, so they take up a lot of space. In addition, the panels have a decent weight, respectively, they can only be mounted on reliable structures.
An alternative to panels can be cork crumb, which is resistant to mold and decay. At the same time, the material is very reliable, since its service life is about 40 years. If joint sealing or underlayment is requiredunder the floor covering, then polyethylene foam is often used as a gasket. True, it can lose about 80% in thickness if the load is too large, and under the influence of moisture, polyethylene foam can become moldy.
Modern soundproofing materials can also be represented by a thin film, which at the same time shows good sound-absorbing properties. For example, many use solutions such as Noise Stop or Shumanet, which are laid directly under the concrete screed.
What about the car?
As you can see, there are a lot of materials with which you can reduce the noise level entering our houses and apartments. However, comfort is required not only in housing, but also, for example, in a car. That is why soundproofing materials for cars are also in demand. Thanks to additional sound insulation, several tasks can be solved at once:
- firstly, the cabin will not be so noisy when the engine and transmission are running;
- secondly, the level of noise entering the cabin from the outside, as well as the noise that occurs at too high a speed, will decrease;
- thirdly, interior parts will not rattle and creak, especially those made of plastic;
- fourthly, it will become warmer in the cabin.
What to choose and where to pack?
Modern soundproofing materials for the car are presented in a huge variety. For example, STP Aero vibration absorbing material can be used to provide additional insulation for car doors, roofs, ceilings, andhood. Bimast Bomb Premium is used on elements such as the wheel arches, trunk and front floor. Noise products belong to the new generation of soundproofing materials.
It is used to create the third layer of the floor, wheel arches and luggage compartment. Materials from the Vibroplast company can reduce the level of vibration in the cabin by insulating the doors, roof, ceiling and hood. They are produced in the form of sheets, so you just need to choose the right size.
Liquid materials called mastic are also popular. For example, liquid "Vibroplast" is suitable for processing wheel arches, and using liquid metal (for example, Noise Liquidator mastic) you can protect the floor in the cabin and the luggage compartment from vibration.
