Apartment entrance door with soundproof function [Selection criteria]☝ Due to many factors, the key to making the home comfortable is the best microclimate and no external noise. The soundproof entrance door will help to ensure the convenience of life and a good mood. A variety of such products are provided in the modern market, and the materials, quality and cost of each door leaf are different. Consider the main selection criteria.
There are many criteria to determine the level of sound insulation of entrance doors.

The materials used in the production of canvas and boxes directly affect the degree of sound insulation. The door leaf must be equipped with materials with improved sound absorption properties.

The canvas with the box must be installed strictly according to the level, even slight deformation is unacceptable. The door should not only protect the living space from external sounds, but also prevent cold and ventilation.
The characteristics of the structure and its ease of operation will depend on them.

It is no secret that popular brands produce higher quality products.

The sound insulation level of the door directly depends on the nuances discussed above, which will determine its performance. The third type of design can reduce 21-26 noise, and the second type can reduce 27-33. Ensure that products with a sound insulation level of 33 are at the top level.

The first-class model can ensure maximum indoor comfort and has good thermal insulation performance. Usually, wood or steel is used to produce imported doors. Both materials have their own characteristics, sound insulation properties, advantages and disadvantages. Therefore, choosing the best solution is not easy.
Steel soundproof entrance doors are the more common solution. Due to the special design, the working characteristics of the blade are significantly improved, but high-quality steel should be used. In the process of manufacturing iron soundproof doors, the first thing to do is to weld the frame and place materials with good sound absorption effect in the frame. Most commonly, foam or mineral wool is used as a filler for metal doors.
In addition to fillers, exterior finishes also help improve the sound insulation of steel doors. For this, the frame is covered with panels or vinyl leather. This material improves the appearance of the finished product and improves its sound insulation.
In addition, in the production process, powder spray is often used. After baking at high temperatures, the resulting coating can significantly improve the resistance of steel to mechanical stress. This kind of iron door prevents theft and damage better than wooden doors, and improves the strength. Therefore, you do not have to worry about the safety of the house when choosing them at work. To make the wooden structure, wood with a sound insulation level of 33 was used. These indicators are characteristics of coniferous trees as well as cherry, oak, and ash trees. The characteristics of the door are directly affected by thethickness of the wood used. The price of soundproof wooden doors may vary greatly. Wood boards are usually finished with natural veneers, which can improve sound absorption and product appearance. The possibility of paint and varnish lining will also enable you to choose the most suitable color option. Because wood is an environmentally friendly material, wooden doors are usually installed by people who care about their health. Various materials are used for soundproof doors, which can also play a sound insulation effect. Each option has its advantages and disadvantages.

In addition to sound insulation, the listed materials also have thermal insulation properties and can maintain a comfortable microclimate indoors. Generally, the thickness of interior decoration does not exceed 51 mm. This option has the best price/performance ratio. The wavy structure of the coating absorbs external sound and prevents heat from escaping to the outside. Therefore, you do not have to worry about heat insulation. But laying mineral wool in a wooden structure is a rather difficult process. You will need to use a special partition to fix the position of the cotton in the canvas. If you abandon these elements, the cotton thread will collapse over time and deliver irrelevant sounds. Usually, the mineral wool will shatter and transfer to the lower part of the structure. You cannot check without opening the canvas. The best solution to prevent unwanted sound from penetrating into the apartment is a polyurethane door. This insulating coating has excellent performance at any temperature and also strengthens the structure. The material does not burn and has advantages when used in residential buildings.
The disadvantages of this option include high cost, so soundproof doors filled with similar fillers are often used in elite villas or new buildings.

Soundproof metal doors with such fillers are the most common. The material is lightweight and can be used for any type of door frame and any accessories. The foam is tough enough and its performance parameters will not change over time. When choosing, be sure to consider the density of this filler. For entrance doors, 26 foam is the best solution.

Many people refuse to use this material due to its flammability and ability to release harmful substances. But this is not always reasonable, because many other fillers have similar disadvantages. Since the foam will be located inside the metal or wood shell, there is no need to worry about the release of harmful substances. This is one of the cheapest materials used for soundproof doors. It is usually corrugated cardboard, which is found in low-quality door leaves imported from China. Of course, this material has certain sound absorption properties, but it cannot be compared with other fillers. The door has good sound and noise absorption; more than one material is often used inside. For example, Izolon placed on different sides of foam or mineral wool will significantly improve the characteristics of the entrance net. For maximum efficiency, position the plasma so that the reflective surface points in different directions. This will reduce indoor heat loss and increase sound absorption by 41%.

Choosing the front door of a soundproof apartment is quite difficult. Each option has its own advantages and disadvantages. The iron structure has strength, good lock quality and reliability. Wooden products have an attractive appearance, and the installation process is not so laborious.
