Modern noise insulation materials: efficiency, technology and choice

Surround yourself with peace and tranquility, each of us dreams. True, there is so much noise around that it is becoming increasingly difficult to protect your home and your relatives from it. To forget about annoying noise coming from the street or from the neighbors from above, soundproof materials help . They are presented in a huge variety, so there is plenty to choose from.

What kind of noise?

Experts divide it into two types - structural and air. The first appears due to, for example, falling something on the floor or rearranging furniture in the room. The second spreads through the air, for example, it can be a radio noise or a phone call. In order to stay in the room 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 noise-proofing Materials allow you to limit the flow of noise in the house or apartment is still under construction.

How to isolate noise?

In the construction process, you can get rid of noise in several ways. The first is the installation of interior partitions and walls. The second is the installation of an additional flooring when the joints are tightly sealed. The third is the reduction in the number of windows and doors. And the fourth way is to hide the engineering communications that make a good noise. For example, using noise insulation materials for walls, it is possible to create a kind of obstacle in the path of the sound wave, and also to promote its absorption and dispersion.

Sound absorption is the number one goal

Soundproof materials for the apartment can be chosen and such that will absorb sounds. They are produced on the basis of synthetic raw materials or natural fibers. Such materials:

- do not burn;

- Pass steam well;

- are environmentally friendly.

You can also use ready-made solutions, which help to get rid of noise. It's about the designs 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 for achieving sound insulation. For example, you can select materials that will isolate the percussion noise. The most popular in this group are light foams in the form of rolls or sheets. They are based on raw materials such as melamine, rubber, polyethylene, polyurethane. Such noise insulation materials for the house are good for insulation of impact noise, for example, when installing an equalizing screed or a floor covering. True, the noise insulation index, which is transmitted through the air, is not very high, so in order to get rid of domestic sounds, they should not be used. Foamed materials are good and as a vibration absorbing gasket. The porous structure excludes their use for facing. Simplicity and simplicity of laying are also distinguished by glass fiber and natural cork - they can be used as a gasket in multilayer structures.

Variety of materials

Most often, to ensure noise insulation uses glass wool, which is characterized by strength, elasticity and vibration resistance. The voids in it are filled with air, so sound absorption is of high quality. In addition, glass wool shows resistance to moisture, has a low weight and has sufficient elasticity.

On the basis of metallurgical alloys, noise insulation materials such as mineral wool are created. The fibers in it are arranged in a chaotic order, so the absorption of sound is good. In addition, cotton wool does not burn, has a breathable structure and is easily cut.

Good for soundproofing and sandwich panels, which include gypsum fiber and mineral wool. True, they are quite thick, so they take up a lot of space. In addition, the panels have a decent weight, respectively, they can be attached only to reliable structures.

An alternative to the panels can be cork, which is resistant to mold and rot. The material is very reliable, since its service life is about 40 years. If a joint seal or substrate is required for a floor covering, polyethylene foam is often used as a gasket. True, it can lose about 80% in thickness if the load is too high, and under the influence of moisture, polyethylene foam can become moldy.

Modern noise-proof materials can also be presented by a thin film, which at the same time shows good sound-absorbing properties. For example, many solutions are used such as "Noisy" or "Schumann", which are laid directly under the concrete screed.

What about auto?

As you can see, there are a lot of materials with which you can reduce the noise level entering our homes and apartments. However, comfort is required not only in housing, but also, for example, in a car. That's why demand for noise insulation materials for cars. Thanks to additional soundproofing, you can solve several tasks:

- First, in the cabin will not be so noisy when the engine and transmission;

- Secondly, the noise level entering the salon from the outside, as well as the noise that occurs at too high speed, will decrease;

- Thirdly, the details of the cabin, especially those created from plastic, will not rattled and creaked;

- Fourth, in the cabin it will become warmer.

What to choose and where to style?

Modern noise-proof materials for the car are presented in a huge variety. For example, the STP Aero vibration absorbing material can be used to further isolate the doors of the machine, roof, ceiling and bonnet. Bimast Bomb Premium is used for finishing elements such as wheel arches, trunk and front floor. Noise products belong to the noise-insulating materials of the new generation.

It is used to create a third layer of floor, wheel arches and luggage compartment. Materials from the company "Vibroplast" can reduce the level of vibration in the cabin due to the insulation of doors, roof, ceiling and hood. They are issued in the form of sheets, so it's enough to just choose the right size.

Popular and liquid materials, which are called mastic. For example, a liquid "Vibroplast" is suitable for machining wheel arches, and with the help of a liquid metal (for example, Noise Liquidator) can protect from the vibration of the floor in the cabin and the luggage compartment.
