The issue of sound and heat insulation is best addressed at an early stage, when it is only planned to purchase and install a new door. As a rule, entrance doors from foreign manufacturers already immediately have a soundproof filling. However, many buyers prefer a domestic manufacturer. Handicraft doors are also common today. Therefore, we will consider the urgent question: how to make soundproofing a door in an apartment with your own hands? The article gives step-by-step instructions, from the choice of materials to the photo of the result. To help the master - video instructions.

We figure out how to soundproof the door to the room without compromising ventilation

The soundproofing characteristics of door structures depend on the material from which they are made. The thicker and heavier the door leaf, the better protection it provides - the so-called mass law works. Lightweight canvases with voids inside reduce the noise level by only 23-26 dBA, and wooden interior doors made of re-glued solid wood already provide quite high sound insulation - within 32-34 dBA.

But the sound penetrates not only through the door leaf itself, but also through the cracks along its perimeter. And here the situation is similar to windows: opening the door reduces its noise-protective characteristics to almost zero.

Therefore, modern noise-protective doors are equipped with seals, which are laid around the perimeter of the door, and special thresholds. The market offers a lot of similar noise-protective door structures.

To make it not stuffy - you need to cut the doorWhat do sellers of soundproof sealed doors forget to warn buyers about? - The fact that such doors cope with the task of soundproofing only where they do not participate in the process of air exchange. For example, the entrance door to an apartment is not taken into account when designing ventilation. On the contrary, its maximum tightness is normalized.

The door of the hotel room does not participate in the air exchange either. But in ordinary apartments, interior doors are directly involved in air exchange, providing the necessary air flow from living rooms to the corridor and further to the exhaust ducts in the kitchen, toilet and bathroom.

The easiest way to provide such a flow is to make a gap between the floor and the door leaf (15 mm for interior doors and 20 mm for doors to utility rooms with an exhaust hood). But then it turns out that they made ventilation - they lost the soundproof properties of the door.

How to ventilate without opening the doorThe answer is simple: you need to make holes in the door for ventilation between rooms. For air flow, special gratings are used. They are installed at the bottom of the door. The figure shows the design of a typical door grille. It does not go beyond the dimensions of the door leaf and has special blinds. This provides visual isolation of the room, but the air passes freely.

Important: The effect of sound insulation in the case of aluminum lamellas will be low. It is better to use grilles with lamellas covered with a porous sound-absorbing material.

The most practical materials for soundproofing

Few people today install a front door with the outside of the door frame. This method allows, if necessary, to increase the level of sound insulation, to organize a small vestibule. There is no need to remove the door, just install an additional door leaf, which will form an air space with the front door. It is this air gap that will provide sound insulation of a fairly good level.

If the already installed door does not allow organizing a vestibule, then the method with the formation of airspace will not justify itself. It will be necessary to remove the door, take out the box. This method is not the easiest and easiest.

Acoustic foam rubber is an excellent budget material for soundproofing a door

A reasonable solution would be to insulate the door with one of the following materials:

polystyrene - the material has proven itself well. It has excellent soundproofing properties. Does not let the cold into the room;
synthetic winterizer is a soft material, but quite stable. It is relatively cheap, but requires a dense layer;
foam rubber is a budget soundproofing material. Suitable for sealing joints, sheathing fabric;
mineral wool is a soft material, most often shrinks over time, accumulates moisture, so it is most reasonable to use cotton wool to insulate cracks;
foam - most often found in sheets. Differs in average sound-proof properties.

All materials are intended primarily for the internal filling of the canvas.

Do-it-yourself step-by-step instructions for soundproofing a metal front door

Consider the sequence of actions to perform independent soundproofing.

Material selection

First, let's prepare the necessary materials:

Noise insulators (such as vibroplast, splen);
adhesive-based vibration isolators (for example, bimast, vizomat);
cement mortar for sealing cracks;
material for decorative finishing (lining, MDF panels);
silicone sealant.

To install soundproofing, you must first remove the old door covering.

Remove the nails with which the artificial leather is nailed to the door leaf.
Remove upholstery.
Remove the layer of hardboard or fiberboard following the artificial leather.
Prepare the door for sound insulation: wipe the inner surface with a solvent.

Installation of insulating materials

After the surface has dried, you can start gluing the sound insulators. For high-quality gluing, it is necessary to maintain the air temperature in the room at least 25 °.

Stick a thick vibration-proof layer of bitumen on the metal using adhesive-sealant.
On top of the previous layer, glue a light, porous, foam-rubber-like noise-insulating layer.
Cut off excess material with a knife.

Sealant for door perimeters

Installation of thermal insulation

This step is optional, but recommended. Thanks to the insulation through the doors, heat will not escape from the apartment. This is especially true for the cold season.

Lay a layer of foam rubber or mineral wool.
Secure it with a fishing net, which is nailed around the perimeter.

Wiring

Laying several signal and power wires is needed for the subsequent installation of an electronic peephole or a radio-controlled lock. It's better to do it right away than to take apart the door later.

All electrical wiring inside the door must be laid before the completion of work and decorative finishes.

Floor insulation in a wooden house from below: materials and installation technology

When purchasing an apartment in a new building, today in most cases the owner has the opportunity to choose its “complete set” or even gets a bare apartment space with an entrance door.In this case, the fight against indoor noise is his personal "headache", removed by the correct selection of materials and technologies used. If the apartment is completed and inhabited, and the issue of insufficient sound insulation arose during its operation, we begin to act.

Interior doors are the main communicator for noise in our apartments. And if the loud sounds that irritate you are not heard through windows and walls, are not transmitted along the floor or ceiling, we proceed to soundproofing the doors.

First of all, you need to determine:

– whether it is required to isolate the room with the source of noise or simply to prevent its penetration into a separate room;

– methodology and budget for fixing the problem.

On the first point, it is important to understand: if it is necessary not to let the sound out of the room, we soundproof all the doors leaving it. If you want to keep sound out of the room - one

And in both cases, we do it from the side of the noise source.

Choosing a solution method

The capabilities of your wallet will be decisive when choosing a way to solve this problem. If its depth allows you to replace the doors with more soundproof ones, choose those made of solid oak, pine or with a sandwich structure and see to it that they are installed correctly. If this pleasure seems too wasteful to you, for soundproofing you will need to purchase:

sealing rubber self-adhesive tape

mounting foam or sealant

threshold, and in the absence of the possibility of its installation - self-adhesive brush tape

any porous soundproofing material with a thickness of 8-10 mm.

This is an almost exhaustive list of what you might need to soundproof a door, but that doesn't mean you need everything listed to solve your problem.

You can and should proceed in the sequence set out in the list and start with a simple sealing of the door with sealing tape and soundproofing the space between the box and the wall with mounting foam or sealant. If there is a gap between the door leaf and the floor, it must be eliminated. If it is not possible to install a threshold, you need to pick up a brush tape and stick it on the bottom of the door leaf (preferably in 2-3 rows). After that check the result. As a rule, these manipulations are enough to achieve the desired result. The fact is that even the cheapest MDF doors, due to their internal structure, are capable of holding sound up to 40 dB, and their serious and expensive additional sound insulation can increase this figure to a maximum of 5 units. The above methods are radically cheaper, and their potential is from 5 to 7 dB.

If it does not help, then proceed to the acquisition of the last two positions of the list. Here it is necessary to remember that the porous material absorbs sound, and in the store you will be advised about a dozen of its items. Carefully read the technical specifications and compare them with the price per 1 sq. m.

In total, do-it-yourself measures for soundproofing an interior door can improve its performance by up to 12 dB, and this is significant.

Noise isolation of the interior door of the apartment

Many people like to have silence in all rooms, and in large families this is sometimes a necessity. Therefore, it is worth saying a few words about the soundproofing of doors inside the apartment. To prevent noise from penetrating into the room, it is necessary to install a special threshold that is combined with a closed canvas. It is desirable to glue the box with a rubber seal. In some cases, the door is sheathed with panels.

For soundproofing an interior door, it can be pasted over with a rubber seal

If silence in a certain room is a priority, then it is best to immediately install a solid door

Pay attention to the position of the door leaf, often due to distortions there are gaps that let noise into the room

To increase the sound insulation of the entrance or interior door of an apartment today is not a big deal. It is enough to have all the necessary tools, choose high-quality material. Today in the construction market you can find a lot of worthy soundproofing materials that will allow you to enjoy the silence at any time of the day and under any conditions.

How to prevent noise from entering the apartment

There are a number of ways to significantly improve sound insulation. Let's consider them in more detail.

Lay another layer of insulation over the door leaf. For this, you can use extruded polystyrene foam or mineral wool. As a result, sound waves passing through these materials are finally extinguished.

Extruded polystyrene foam dampens extraneous sounds well

Use as the main insulating material a metal foil on a soft base that reflects sound vibrations.
Install the insulation strips on the door leaf or box. Why is it necessary to accurately measure the doors and mark the strips, leaving room for the hinges. After mounting the planks, cover them with flexible tape, which will ensure a tighter fit to the box. Attach threshold rails and brushes.
Install 2 entrance doors with a vestibule between them. The resulting layer of air will significantly reduce the noise level. Equip the outer door with burglary protection, and cover the inner door (serving more for decorative than protective functions) with panels or clapboard.
To seal cracks, instead of mounting foam (poorly insulating against noise), use a mixture of cement, which, after drying, is treated with silicone sealant.

To start work, you need to prepare all the necessary tools and materials

Soundproofing front door with removable lining

To install the soundproofing of the front door, it is best to arm yourself with the following tool:

wood saw;
electric drill;
hammer, scissors, knife;
silicone sealant;
glue, fixing materials.

Doors with removable lining are filled with soundproofing material

A decorative panel is removed from the door with a removable lining, after which the space is filled with mineral wool or other material. The inner metal sheet is removed, if present, and the cavity is filled with soundproofing material, which is fixed with glue.

Advice. The gaps between the inner sheet and the frame are best sealed with sealant.

But how to mount the material if there is no inner sheet? In this case, a frame is preliminarily created, which is mounted inside the front door. The insulation material is carefully laid, the internal cavity is sewn up with plywood. At the final stage, a peephole, elements of door fittings are installed.

Soundproofing front door with fixed paneling

There are two ways to increase the sound insulation of a door with a fixed door leaf trim:

Upholster the canvas with synthetic winterizer, polystyrene foam, polystyrene.
Glue bituminous vibration and noise insulators.

At the first stage, it is necessary to degrease the entire surface of the door leaf with acetone. You can use another solvent, as long as the surface is clean and fat-free. After the canvas has dried, you can proceed directly to gluing. First of all, a sheet of vibration isolator is glued to the metal, and noise insulation is glued on top. It is recommended that the sheets overlap each other during gluing.

Attention! This method requires some nuances. The ambient temperature must be at least +25C, work should be done in the warm season

At the end, the door leaf can be pasted over with artificial leather to give an aesthetic appearance.

Door with fixed skin can be upholstered with soundproofing material

The greater the thickness of the soundproofing layer, the better and higher the quality of sound insulation will be.A steel door, as a rule, is upholstered with artificial leather, sometimes foam or synthetic winterizer will be used. The cladding is fastened with special nails and glue. Today, the method of upholstery of the front door with non-removable sheathing using fiberboard and MDF is gaining popularity. This method involves more complex work.

First of all, a wooden frame is created from 20 mm planks, after which the structure is attached to a steel door with self-tapping screws. The resulting cracks are sealed with a heater. On top of the frame, fiberboard, MFD panels are attached.

Attention! This method of sheathing significantly increases the weight of the door.

It is important to make sure that additional hinges are pre-installed
