Soundproofed entrance doors: types of materials used and selection criteria

Comfort in the home is achieved due to a large number of factors, the key of which are the optimal microclimate and the absence of extraneous noise. Entrance doors with sound insulation will help ensure the convenience of living and good mood. A wide range of such products is presented on the modern market, each door leaf is distinguished by its material of manufacture, quality and cost. Consider the main selection criteria.

Criteria for the selection of noise insulation doors

There are many criteria that determine the level of sound insulation of the front door. When choosing such a product in an apartment, you must take into account:

  • Variety and properties of plating. The material that was used in the manufacture of linen and boxes, directly affects the degree of sound insulation.
  • Type and characteristics of the filler. The door leaf is necessarily equipped with materials with enhanced sound absorption properties.
  • The quality of installation of the entrance door. The canvas with the box should be set strictly on the level, even minor distortions are unacceptable.
  • The level of insulation. Doors should not only protect the living space from extraneous sounds, but also from cold and drafts.
  • The number of sealing circuits. The characteristics of the structure and the convenience of its operation will depend on them.
  • The name of the manufacturer. It is no secret that popular brands produce higher quality products.

From the above nuances directly depends on the class of noise insulation of the door, which will determine its performance. The constructions of the third class can reduce the noise by 20-25 dB, the second - by 26-31 dB. Products that guarantee a sound insulation level of 32 dB belong to the first class.

First-class models are able to guarantee the maximum level of comfort indoors and also have good thermal insulation.

Web design

Usually wood or steel is used for the production of entrance doors. Both materials have their own characteristics, sound insulation performance, strengths and weaknesses. So choosing the best solution is not so easy.

Steel door

Entrance noise insulation door based on steel is a more common solution. Due to the special design, the performance of the fabric is significantly increased, but on condition of using high quality steel. In the process of making an iron noise insulation door, the first thing to do is weld the frame, into which the material with a good sound-absorbing effect is laid.

Most often foam or mineral wool is used as a filler for metal entrance doors.

In addition to the filler, the exterior finish helps to improve the sound insulation of the steel door. To do this, the frame is upholstered with MDF panels or covered with vinyl artificial leather. Such materials improve the appearance of the finished product and increase its noise insulation.

Also in the production process is often used powder spray. After baking at high temperatures, a coating is obtained, which significantly increases the resistance of steel to mechanical stress. Such iron doors are protected from burglary and damage better than wooden and have increased strength. So when choosing them, being at work, you should not worry about the safety of your home.

Wooden door

For the manufacture of wooden structures used wood with a sound insulation level of 32 dB. Such indicators are characteristic of conifers, as well as cherries, oak, ash. The thickness of the used timber directly affects the characteristics of the door. The cost of wooden noise insulation doors can vary quite a lot.

Wooden canvases are most often finished with natural veneer, which improves sound absorption and the appearance of the product. The ability to paint the lining will also allow you to choose the most suitable option for color.

Since wood is an environmentally friendly material, people who take care of their health often install doors from it.

Soundproofing Materials

For soundproofing doors using various materials, which also act as insulants. Each option has its strengths and weaknesses.

Most often give preference:

  • foam plastic;
  • mineral wool;
  • foamed polyurethane;
  • corrugated board.

These materials, in addition to sound insulation, also have heat-insulating properties and are capable of maintaining a comfortable microclimate in the room. Usually the thickness of the interior does not exceed 50 mm.

Mineral wool

This option has the best value for money. The wavy structure of the coating absorbs external sounds and prevents heat from escaping to the outside. So what about the insulation can not worry. But laying mineral wool in wooden structures is a rather difficult process. You will need to use special partitions to fix the location of the wool inside the fabric. If you abandon these elements, wool will eventually begin to crumble and skip other sounds.

Often, mineral wool showered and shifted to the bottom of the structure. Check this without opening the fabric is not possible.

Polyurethane foam

The best solution to prevent the penetration of extraneous sounds in the apartment is a door based on polyurethane. This insulating coating has excellent performance at any temperature, and also strengthens the design. The material does not burn, which is an advantage when used in residential buildings.

The disadvantages of this choice include the high cost, so soundproof doors with a similar filler inside are often used in luxury cottages or new buildings.

Styrofoam

Soundproof metal doors with such filler are the most common. The low weight of the material allows it to be used in a door frame of any type and with any fittings. The foam is quite hard, so that over time its performance parameters do not change.

When choosing, be sure to consider the density of this filler. For entrance doors, C25 foam will be the best solution.

Many refuse to use this material because of its flammability and its ability to release harmful substances. But this is not always justified, since many other fillers have similar disadvantages. Since the foam will be located inside the metal or wooden shell, you can not worry about the release of harmful substances.

Corrugated cardboard

This is one of the representatives of the cheapest materials used for soundproofing entrance doors. Often, it is corrugated cardboard found inside the low-quality door panels from China. Of course, this material has some sound absorption, but it does not compare with the performance of other fillers.

Extra insulation

In order for the door to have a good level of sound and noise absorption, quite often not one material is used inside. For example, izolon, which fits from different sides of the foam or mineral wool, will significantly improve the characteristics of the entrance fabric.

For maximum efficiency, the isolon is positioned so that the reflective surfaces are directed in different directions. This will reduce the loss of heat in the room and improve sound absorption by 40%.

Select the front door to the apartment with sound insulation is quite difficult. Each option has its advantages and disadvantages. Iron structures have strength, good quality locks and reliability. Wooden products have an attractive appearance, and the installation process is not so time consuming.

In Moscow, the sale of doors with sound and heat insulation is carried out by many companies that are located on different streets, and their range is represented by a large number of manufacturers. Order can be made directly on the website of the selected company or by phone with the possibility of delivery and installation. The cost of doors with sound insulation varies greatly and is in the range of 10000-50000 rubles.
