Sound insulation in a wooden house

Private houses have recently become more and more popular, because many city dwellers are trying to move out of town in order to enjoy peace and comfort. At the same time, they do not want to go far from megacities. Despite their comfort and coziness, wooden private houses have some drawbacks. Often such a disadvantage in a private house is the excessive sound permeability of the walls.. Let’s try to figure out how to make the correct sound insulation in a wooden house with our own hands, and what materials are better to use for this.

The need for noise isolation

Let’s start with the fact that sound insulation should be in any building. Indeed, a large number of different types of noises that will affect the inhabitants of the house are unlikely to contribute to a cozy atmosphere. But it should be said that when creating sound insulation of premises, different sources of noise and different types of noise are identified. Internal ones do not create any discomfort for a person, but external ones are of several categories. And modern insulators should be chosen with this factor in mind.. By the type of transmission of impact, noise or sound waves are divided into:

  • air;

  • drums;

  • structural.

If we talk about air, then their transmission is carried out by air, they have no connection with fences and for them a simple enough noise isolator. If we talk about percussion, then they appear when things come into direct contact with surfaces. But the structural ones are formed after the object of influence enters the structure of the overlap. This type of wave can travel long distances in a building..

You will first need to examine the walls for problem areas. Particularly much attention should be paid to cracks and gaps in the joints of communications.

After that, it is necessary to close all the holes next to the sockets well. The best way to do this is with fiberglass..

Other aspects can also increase the level of sound vibration:

  • the use of low-quality fittings, as well as the presence of gaps in door and window frames;

  • building materials from which the house is made, having low noise insulation performance;

  • improperly selected finish, due to which it weakly absorbs sound vibrations.

Sometimes, to improve sound insulation, it is enough to perform the following actions:

  • replace the old door with a new one, which will have sealing substrates around the perimeter;

  • install gaskets on the passages between rooms;

  • replace wooden windows with double-glazed windows or PVC analogs;

  • finish the facade of the building with materials that have high reflective properties.

If this does not help, then more serious complex work is required..

Possible materials

There are quite a few materials that can muffle or reflect sound.. Some are classified as artificial, while others are natural. They have different sound insulation characteristics and weight. Let’s consider them in more detail.

The first is cork soundproofing.. It is distinguished by high plasticity and thinness. It is created in the form of plates and has a high price. Excellent for noise insulation inside the house due to its low weight and dimensions. Perfect for rooms, as it has an attractive appearance.

The next material is loaded vinyl, or noise block. It is perfect for small rooms, it is produced in the form of a film with a thickness of no more than 2.5 mm. It has a high density, which provides good sound-absorbing characteristics of the material. A sheet of vinyl like this can hold up to 25 dB. In addition, it has increased resistance to natural factors, in particular, moisture..

Substrates are another type of material that can be used for soundproofing. They are usually glued directly to the walls under the wallpaper. It is the low weight that is an advantage, but one should not expect very serious noise absorption from them..

Mineral wool is a material composed of fibers. It also has not very high sound-absorbing characteristics. It is usually used for insulation of external surfaces. Given the large thickness of the material, it is better not to use it for work inside the building..

The next option that can be used for sound insulation at home is expanded polystyrene. It belongs to the category of synthetic and is produced in slabs. It is environmentally friendly and completely safe for humans. It copes well with the effects of natural factors and has a long time of use. Can completely block 4 dB of sound. Usually it is used in combination with some other materials, which allows you to achieve a good degree of noise absorption..

Another material that needs to be said is ZIPS. This abbreviation stands for Soundproof Panel System. Its sheets are usually mounted on walls under wallpaper or other finishes. Such a panel usually has several layers and belongs to the category of sandwich sheets. Usually, the ZIPS structure includes staple glass fiber and a gypsum fiber sheet, which is required to provide increased rigidity and resistance to mechanical deformations. Such panels can have a thickness of more than 4 centimeters due to the presence of built-in vibration damping units..

Another interesting material is fiberglass. From the name you can understand that it is created from glass. At the same time, it is a flexible and reliable solution that can be used for insulation and insulation. It is usually used in partitions as a middle layer. In frame structures, sheets of fiberglass are used to make interior partitions.

You can also use drywall. There are special sheets of such material that allow you to create wall decoration. They have the highest density, low bending stiffness, and high mass, which allows you to get maximum protection against vibrations. They are used to create frame walls between rooms. They are also used to improve the sound-absorbing characteristics of the interfloor overlap. If desired, you can use ordinary drywall sheets, but only by creating sandwich panels.

When combined with a number of materials, you can get pretty good soundproofing structures. This design will allow you to absorb up to 10 dB.

How to make soundproofing?

After all the necessary measurements and the acquisition of the required material, it is necessary to carry out work to completely cover all possible directions of movement of sound waves in the room. That is, it is required to close the sockets, plumbing openings, heating and telecommunications openings.

The very process of creating sound insulation is divided into three stages:

  • for walls;

  • for the floor;

  • for ceiling.

Now let’s take a closer look at each stage..

Walls

Walls in a house that has wooden floors are more often subjected to various kinds of loads than the floor or ceiling. To improve their characteristics, they usually use basalt or mineral wool..

We will analyze how noise insulation of interior partitions is carried out.

  • It is required to attach wooden beams to the walls in a horizontal position, which is necessary to create ventilation. In fact, such slats are crate.

  • To the created frame, you need to attach a film to isolate vapors.

  • Now you need to make the vertical part of the frame. It is better to create it from light metals..

  • Between the racks we lay out pieces of mineral wool or ZIPS panels, after which we fix the material with the help of rails.

  • Apply the second layer of vapor barrier film on top.

  • It remains to apply the finishing, and the process of soundproofing the walls will be completed.

Floor

To protect against noise that comes from below, it would be better to use a material such as basalt wool or ecowool. Their advantage is that they have a high density. In addition, it will not be a bad decision to install an additional underlay of rubber or cork panels under the laminate or any other floor covering.. The process of soundproofing the floor will consist of the following steps:

  • first you need to remove the old floor covering, then lay a layer of waterproofing on the logs and in the space between them;

  • it is required to lay a sound-reflecting layer on it;

  • now a third additional waterproofing layer is being applied;

  • rubber-cork panels are laid;

  • chipboard slabs are placed on top of the resulting structure.

To insulate empty space in places where there is a joint between the floor and walls, it would be best to use a material such as felt..

Ceiling

It is possible to carry out noise insulation of the ceiling both from the outside, from the attic, and from the inside.. If a person lives, for example, in a two-story house with neighbors, then all work should be discussed with them..

If we talk directly about the process of soundproofing the ceiling in the type of buildings under consideration, then it will be carried out as follows.

  • It is required to completely dismantle all materials from the ceiling.

  • Now you need to attach a vapor barrier tape to it. To secure it, it would be best to use a construction stapler..

  • Between the timber and the suspended ceiling, it is necessary to fill the space with high-quality soundproofing materials. These can be called those that have a small mass and high sound absorption characteristics. For example, foam plates, basalt wool and various kinds of insulation materials, which are produced in the form of rolls.

  • If the ceiling is made of wooden slats, parts of the mineral mats will need to be placed between them..

  • Now it remains to apply only the final finish, and the ceiling will be ready.

Recommendations

When implementing sound insulation in a wooden house, you need to know the specific specifics of this process. For example, before purchasing insulating materials for walls and ceilings, everything should be inspected for the presence of various defects, and then they should be repaired. Such preliminary preparation cannot be neglected, because it can significantly affect the result of the work..

If the preparation is carried out poorly, then the optimal result will not be fully achieved.. And also special attention is required to be paid to the so-called problem areas. The most problematic area will be windows and doors, because they allow cold and wind to pass through. They must be prepared in advance in compliance with all GOST standards. This will also require the installation of sealed metal door leaves and high-quality modern double-glazed windows..

In addition, you should use only high-quality natural materials from trusted manufacturers, which will eliminate the possibility of buying low-quality soundproofing materials..
