Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

The most important element of a residential building or apartment is sound insulation. The less extraneous sounds and noises enter the room from the street or from neighbors, the more comfortable the residents will feel. The owners of apartments and houses located next to busy roads or railways pay most attention to floor sound insulation. Insulation materials, as well as modern flooring technologies, help to reduce noise and vibration load. A wide range of noise isolators is presented on the Russian market. Recommendations of our experts will help you to choose the material that is optimal for the price and characteristics.

Recommendations for choosing sound insulation

Noise reduction index. To assess the effectiveness of a material, manufacturers indicate a parameter such as a noise reduction index. Most often it denotes the level of noise reduction with a single layer of insulator installation. On average, the noise reduction index for most materials is in the range of 20-30 dB. This will be enough if a high-quality floor or floor is made in the apartment, which delays up to 50-55 dB. Measurements show that the cry of a child or the cry of an adult reaches 75 dB.

Environmental friendliness. Sound isolators are made from various natural and synthetic materials. Therefore, the degree of influence on the human body is different for them.

  1. The safest are considered to be noise insulators made from natural raw materials. These can be natural minerals or plant products.
  2. Modern synthetic sound insulators are made without the addition of harmful compounds. Increasingly, manufacturers are abandoning such a binder, such as phenol-formaldehyde resin.
  3. Some noise insulation materials are dangerous to the human body only at the stage of moving or laying due to the formation of dust. In the future, they do not pose a danger to the residents of the house.

Strength. Since the floor is subjected to the highest loads, strength will be an important characteristic of the sound insulator. Some materials are highly elastic, others are small. The strength of the noise insulator may decrease over the years, this indicator is negatively affected by UV radiation, moisture and temperature drops.

Installation technology. When choosing a soundproofing material, it is important to consider the installation technology.

  1. At the construction stage, the best option would be to lay a sound absorber under the screed or between wooden logs. A thin underlay will be required for finishing flooring.
  2. If there is no air gap between the screed and the floor covering, foam products should be preferred.
  3. Soundproofing boards are stacked close to prevent sound waves from entering the room through gaps and joints. Ease of installation will depend on the ease of cutting, the method of fixing and the thoroughness of the preparation of the base.

We have selected 14 of the best materials for floor sound insulation for our review. All of them are sold in construction stores in the country. When allocating seats, the editorial board of the magazine relied on the opinion of the expert community, taking into account the reviews of Russian consumers.
