Soundproofing of buildings has great importance for human health and comfort. In particular, noises in the workplace not only affect the -working climate-, but also significantly limit the ability to concentrate and perceive. At high noise levels soundproof doors production of MGK-Group provide optimal protection.

They provide pleasant acoustics, reduce noise emissions, increase work efficiency and protect health. Due to the special design of the door leaf, certified insulating material and special door seals ensure optimum sound insulation values. When used as a multi-purpose door, a combination of fire and smoke protection and thermal insulation properties is additionally also possible. Since in reality there are no ideal conditions, 5 dB should be subtracted from the tested sound insulation value. To customize the specificity of the noise source, a wide range of protection from 28 dB to 45 dB is offered for any construction situation. Areas of use of soundproof doors: doors for hotels; doors for offices, in meeting rooms; doors for recording studios.

Soundproof doors and fire doors are similar in design. Colors and all kinds of textures finishing materials used in the manufacture of soundproof and fireproof doors, allow you to solve the most sophisticated design solutions... The standard door leaf thickness ranges from 40 to 59 mm, and the door dimensions allow it to be built into a wide variety of openings.

We produce soundproof doors with the following types of coatings:

• Finishing Film

If you can't put wooden threshold in soundproof doors, we can offer you automatic soundproof up to 48 db thresholds manufactured by "PLANET", built into the door leaf.

Since various plates are used in the manufacture of soundproof and fireproof doors, doors can only be made smooth, with an overlay infill and with a milled infill. The canvases can be either without a fold (quarter) or a rebate.

Absolutely all models have excellent sound insulation. entrance doors Torex. This became possible due to the fact that the products are equipped with a unique multilevel system protection from sounds. It is provided, on the one hand, by a double contour of the seal around the perimeter of the door and the box (one of the contours is magnetic). On the other hand, sounds from the outside are successfully damped thanks to the multilayer soundproofing material. You will feel at ease outside the Torex doors at any time.

In most models of noise-insulating input metal doors Torex box is filled with high density mineral board. If necessary, during installation, the box is additionally insulated with polyurethane foam.

Depending on the type of door, the following insulating fillers are used in the door leaf:

• The doors of TM Professor use a three-level protection structure. In addition to the high-density mineral board (60 mm thick), a 3 mm thick isolon layer and a layer of heat-insulating cork are laid. This combination of materials and their location relative to each other is optimal for minimizing the level of noise and cold entering your home from the outside. Izolon also performs vapor-repelling functions. This is especially true for those who live on the ground floors. In the cold season and during the rainy season, the vapor-repellent capabilities of Isolon will reliably protect your apartment from moisture and vapors from the street. Also mineral slab used in the Ultimatum series.
• Filling the door leaf with rigid polyurethane foam - a patented technology that made it possible to raise performance characteristics doors for more high level... This provides additional protection not only against noise and drafts, but also against freezing of the structure. When using polyurethane, the door becomes more resistant to deformation, since the hardened material acts as stiffeners. This material environmentally friendly. It does not highlight harmful substances and is widely used for insulation cold rooms... The pouring structure, patented by Torex, provides the unique heat and sound insulation properties of doors in the Super Omega, Super Delta and Ultra-M series.
• High density mineral board is used in technical doors. V fire doors high density basalt fiber board is used, which is able to resist fire.

Interior doors are both a way to fence off, close a room from prying eyes, and an important decorative element interior that requires special attention.

It is also a sound barrier for a place where privacy reigns supreme.

Thus, the modern requirements for doors inside the dwelling are as follows.

They should be:

• ergonomic (easy to use, lightweight, pliable);
• durable (resistant to various influences, be it moisture, dust, mechanical damage, chemical treatment detergents and high-temperature devices);
• aesthetic (stylish, beautiful);
• act as a sound barrier (have good sound insulation and noise reduction).

Unfortunately, today not all models of interior doors on the consumer market satisfy the above requirements.

Sound insulation of interior doors is a question that worries a lot of people, however, this process is not an isolated process, but is included in a whole range of measures. They also imply isolation from extraneous noise and sounds by sealing walls, ceilings and eliminating gaps between the floor and the bottom of the canvas.

That is why soundproofing only interior doors is impractical and does not always bring the desired result. This paradox is connected with the fact that sometimes the materials from which the walls and ceiling are made have greater sound conductivity than the door leaf.

And here https://vekrosta.info/lp/newlanding/ you will find reviews and a new recruiting site for the entire team.

Factor # 1

Soundproofing with an interior door is possible only under certain conditions. One of them is the material from which the door leaf is made.

Interior doors can be based on:

• plastic sheet;
• metal;
• fiberboard sheets (pressed wood);
• solid wood;
• glass or mirror sheet.

The most negative reviews on the issue of soundproofing have glass and plastic doors, as well as those that, although made of wood or fiberboard, have inserts from such materials.

The aluminum profile also has high rate sound conductivity. The most popular are solid heavy massifs from natural tree species, as well as lighter ones from pressed wood.

Factor # 2

The second factor affecting the soundproofing and soundproofing properties of interior doors is the type of construction of the door leaf itself.

There are such types of canvases:

• solid;
• hollow;
• with filler;
• with inserts.

Models based on a hollow structure are the worst protected from noise, since due to its resonant properties, sound absorption does not occur. Also low threshold soundproofing have door leaves with glass inserts skipping sound. The best interior doors with sound insulation have a solid wood or fiberboard, filled with glass wool or foam.

Factor # 3

What does a soundproof door consist of?

The third factor, and probably the most significant, is the type of door.

According to this classification, the following varieties are distinguished:

• swing or panel board (single-leaf, double-leaf);
• folding ("accordion");
• compartment (sliding, sliding);
• swinging (cowboy).

The last type has nothing to do with sound insulation - it's just a tribute to fashion or a detail of a design concept. The folding type will also not provide the required level of protection against noise and extraneous sounds due to their lightness and material (they are often made of plastic, cardboard or thick fabric).

Sound absorption level at sliding doors higher than the previous types, but lower than the swing ones. However, this disadvantage is easily eliminated by reducing the gaps between the wall and the door leaf.

To do this, you can replace the skirting board with a thin strip, install cut-in carriages on top, and glue a seal on the platbands and track strip. Such measures will make it possible to increase the airborne sound insulation index practically to the level of swing doors.

Differences in barriers

It is customary to distinguish noise-insulating and sound-insulating interior doors from each other. The difference between them is that a soundproof interior door is installed where it is important to provide a quiet and calm atmosphere, for example, in a nursery, bedroom or study.

Under fundamentally opposite conditions, when there is a certain place in which noise and loud sounds are constantly concentrated (in the playroom, in the music room), it is necessary to install noiseless or noise-insulating plates that do not let them out.

Refinement of sound absorption at home

The best soundproofing of the door is achieved by filling the voids of the door leaf with special acoustic materials sound absorbing (mineral wool, foam rubber, polyurethane foam), as well as with an outer upholstery in dense fabric or leather.

Another step to soundproofing the room is to seal the door with slats that minimize the gap with the wall. This option is most suitable for sliding compartment models.

It is not worth excluding the option of installing two doors, which will give a greater effect than installing one specialized soundproofing array.

Summary

Summing up all of the above factors, we can say that the most ideal silent interior doors will not be able to fully protect against extraneous sounds if there are plasterboard walls in the room.

And choosing among folding, sliding and swing doors, you should not be guided by fashion trends and real functionality these models, giving preference to the latter, due to their versatility and greater reliability.

Noise is a common irritant in human life. He can stalk him at work, preventing him from concentrating, at home, interfering with comfortable rest, in the hotel, where it is produced by the guests' neighbors, and in many other places. For example, according to their intended purpose, doors in dental offices, executive offices, premises in educational institutions.

To give this property in modern production apply various technologies... For example, interior noise-insulating doors can be made of a solid block of sufficient thickness. Wood, due to its sound insulating properties, will leave noise outside. In another case, the door inside is filled with a special material that provides silence in the room behind it. The main thing is that it is not hollow, otherwise the opposite effect will occur, and external sounds will resonate.

However, in residential premises, situations may arise when it is structurally impossible to provide a threshold in the opening, for one reason or another. Then the installation of a canvas and a box, even with improved soundproofing qualities, will not help. In this case, on help will come soundproof door to the room with the system " Smart threshold". She does not require floor mounting, since it is arranged directly in the sash.

System design "Smart threshold"

This sealing system is good for installation in both conventional and reinforced doors. It is automated, which ensures its easy operation when opening the door and high-quality hiding of the lower gap when closing. The distance from the floor to the edge of the blade is filled with an oil seal, leaving no gap. It is equipped metal spring, which raises the seal at the same time as opening the door.

If you decide to buy soundproof wooden interior doors, then the system will be mounted directly into the door leaf. When choosing plastic or glass - it is possible to mount the mechanism externally in the form of a decorative overlay.

Soundproofing the door to guard productive work

Noise is often a negative factor that interferes with focusing on something important. This problem is especially acute for office workers, whose tasks require the utmost concentration. For business owners, when arranging places for such workers, it is important to buy noise-insulating white office doors, which will ensure productive and calm activities.

Those people who often have to be on business trips due to the nature of their work may face the problem of annoying noise in hotel rooms. Considering that there can be more than a dozen rooms in one hotel corridor, walking and loud conversations will be a distraction around the clock. Therefore, the owners of accommodation companies who really care about their guests should think about the fact that soundproof doors for hotels will significantly raise the status of the hotel and attract big number guests from the business community. Not to mention the fact that such an additional option will also appeal to other categories of clients, including mothers with small children or the elderly.

How to buy an interior soundproof door

To choose and buy a soundproof interior door, feel free to contact our company. We advise you to purchase such products to order with delivery, so that the structure is manufactured in compliance with all standards and taking into account the conditions of future operation. Personal production from the manufacturer does not mean at all that the price for interior soundproof doors will be high. But the equipment with the Smart Threshold system will bring a number of additional advantages:

• Protection from extraneous sounds, drafts, odors, light.
• No obstacles to free movement between rooms when the door is open.
• Safety, practicality and design convenience.
• Service life up to 15 years.

To do right choice, we recommend reading about the sound insulation properties of various types of doors on our website. We also draw your attention to the fact that this section of the site presents door products that are manufactured according to individual sizes customer, which makes it a product endowed with specific properties and characteristics. We remind you that such products are subject to Article 26.1 of the Consumer Protection Law.

Article 26.1. Consumer Protection Law. The consumer does not have the right to refuse a product of proper quality, having individually defined properties, if the specified product can be used exclusively by the consumer who purchases it.

Noisy neighbors, children or adults living in the same room can interfere with each other. To solve the problem, soundproofed interior doors are installed in each dormitory. The soundproofing of the structure depends on the parameters described below.

With increased protection against sound waves, there are:

• plastic;
• from multilayer fiberboard;
• metal;
• glass.

The doors have a cardboard partition inside, arranged according to the honeycomb principle. The filler has good elasticity, practically does not transmit sound.

Sliding structures can be metal or plastic. They are considered the worst sound deadeners due to the clearances required for comfortable door use. Because of design features there is no way to improve performance.

And also poor protection against sound penetration in models made using panel technology. Their frame is sheathed / chipboard, and inside there is a resonating void. You can improve the soundproofing of the canvas by filling inner space material that does not allow noise to pass through.

Attention! Interior doors with increased level soundproofing are made of.

Glass inserts, mirrors reduce the level of noise absorption. Glass elements should occupy no more than 20% of the entire area of ​​the door leaf ( optimal size). For large inserts, it is better to choose double or triple glass.

The sound insulation level depends on the distance between door frame and a sash. Standard designs have a wide opening. Among all models, only soundproof interior doors with a double rebate do not have gaps. They have a protruding groove, inside which a polymer seal is located.

From manufacturers, you can order doors made of several layers of soundproof materials, lined with chipboard. Outwardly, they look like ordinary interior models, but they delay sounds more.

If with a multi-chamber interlayer of a double-glazed window, then the sound insulation rate increases higher. Such door panels can be found in offices, public places - they are rarely used in apartments.

Important! To enhance sound insulation, a special metal box is installed, which makes the door gap less than 1 mm. Inside it is filled concrete mix or polyurethane foam.

How to choose a door with good sound insulation?

Wide the lineup and a long list of manufacturers causes a "stopper" even for specialists. The choice of soundproof interior doors is an optimal balance of several parameters:

• the material from which the canvas is made;
• total thickness;
• type of cladding;
• design features of the canvas.

Among the materials that are effective in the fight against sounds, there are natural wood. Wooden structures reduce the noise level by 10-15 dB. Made by panel technology, the doors are hollow inside, causing the opposite effect - acoustic. To eliminate the void, they are filled with sound-absorbing material.

Additional noise protection can be created using metal foil. The usual one does not fit, it is necessary to buy on a soft base - it is easily attached. Sound waves bumping into an obstacle are reflected, but do not resonate.

What are the fillers to provide sound insulation?

Soundproof materials suitable for improving the performance of door structures:

• corrugated cardboard;
• basalt mineral wool;
• Styrofoam;
• foamed polyurethane.

Corrugated cardboard is laid between the sheets according to the honeycomb principle. The material is inexpensive, dense, but loses its structure over time. For doors designed for 2-5 years of operation, the filler is suitable.

Minvata is a non-combustible material. It settles over time, forming voids between the canvases. You can solve the problem by installing stiffeners. They will keep the cotton in place without letting it fall. The best option- replace the door leaf after a few years.

Polyfoam provides good soundproofing, dense, holds its shape, but fire hazard. Gives off toxic gas when burning.

Polyurethane practically does not burn, dense, fills all the cracks. Great option for continuous operation.

How to make noise insulation with your own hands?

H, they need to be slightly modified. The process is simple.

For this:

1. We carefully look at the distance from the wall to the door frame. The cracks found there, cover up with a sealant for high-quality insulation from the noise.
2. We glue soundproofing material to the door. It can be synthetic winterizer, foam rubber, soundproof panels sold ready-made.
3. We glue a seal or a profile cord between the canvas and the box.

You can decorate with leatherette or other suitable material... To keep it, we nail it along the perimeter with small nails with decorative hats. The cladding plays a decorative role, increases heat and sound insulation.

Sliding doors are soundproofed according to a different principle:

• install a plinth between the wall and the door frame;
• cover the gap at the ceiling with a carriage;
• between the canvas and the wall we glue on the strip, platbands, brush seals.

Additional methods of soundproofing

Thresholds become a real obstacle for young children and the elderly. To solve the problem, the threshold is removed, and a hidden structure is installed in the door.

1. The flexible threshold is made of rubber, tightly covers the gap in the lower part of the door, does not interfere with operation. The sound absorption level increases several times.
2. "Smart" threshold - made of a seal, attached to the door. When opened, it rises, when closed, it goes down. Excellent draft protection.

A thick oak door is a good soundproofing, but not suitable for all rooms. It is better to put lightweight models from quality materials... For a children's room, it is worth choosing models without glasses, with a simple locking system.

Remember! The soundproofing of a room does not depend only on the doors.

The ceiling, walls and windows also let sounds through. Windows can be replaced with metal-plastic ones, and sound-insulating material can be glued to the walls and ceiling.

They help to delimit space, protect from extraneous sounds. For these purposes, choose door leaves with increased noise insulation based mineral wool, corrugated cardboard, polystyrene foam, foamed polyurethane.
