Any overlaps is a potential source of heat loss and
Penetration of noise.
In the case of wooden beams, it can be noted that
Wood perfectly spends sound. Plus, tree beams, with time begin
make creak.
To avoid this, you need to take care timely
Proper sound insulation overlaps (noise insulation).
Soundproofing of wooden floors in the house
By nature, the sound is divided into three types:
- Shock noise. Reflects the sound of steps, drop items,
Moving furniture. Characterized by the index of the reduced level of shock noise
Lnw;
- Air (acoustic) noise. Sound waves that
Transmitted by air. The source can perform the voice of the residence, the sound of the television
and video equipment, etc. It is characterized by an RW air noise insulation index.
- Structural noise. In essence, this is a kind of shock noise, in
The difference from which the noise conductors are the Connection Places of Connection
constructions.
Select sound insulation material for overlaps
To ensure better protection against noise and vibration,
Soundproofing of inter-storey wooden floors is carried out using
several types of insulators. The main requirement is a high coefficient
Sound absorption of building materials.
Soundproofing of inter-storey wooden floors of minvatayv as the main sound insulation is better to give
Preference to fibrous materials, because their structure contributes to the fact that
Most sounds come out about it (i.e., the maximum
Sound absorption).
For example, equating, mineral and basalt wool possesses such characteristics. In addition, such a sound insulation material serves simultaneously and insulation.
Soundproofing of wooden floors - draft floor chipboard - Speed isolation from sounds will create arrangement
draft floor from chipboard or OSB. At the same time, sheets are not attached to lags, but fixed
Between self-drawing or nails. In the beams, such a floor is held under
Own weight (on the principle of floating gender). And thanks to the absence
The hard compound with the overlap is reduced by the probability of penetration of noise
from outside.
Soundproofing between the wall and overlapping, the sound penetrated between the overlap and the bearing wall, as well as between the overlapping and chimney, it is recommended to place a roll insulation in the seam, for example, felt or in the structure of it is similar. And the location of the connection is to close the plinth. Moreover, the plinth is nailed only to the wall.

Soundproofing of wooden floors - felt on the beamed felt felt on the beams also reduces the level of noise.
Soundproofing of wooden floors - substrate strokes with a polystyrene and / or foil substrate, or a substrate from a natural plug under the flooring will also reduce the level of impact noise and vibration.
It is worth noting that all types of sound insulation works
The floors must be performed at the construction stage of the building. Location scheme
Materials are presented in the figure.
Soundproofing of wooden floors between floors - norms and requirements
Despite the general approach to the selection of noise insulationMaterial, sound insulation of wooden floors of various purposes is carried out
With compliance with different requirements.
- Soundproofing overlap of non-residential attic on wooden
The beams are considered to be performed effectively, if an air noise isolation index
RW is at least 45 dB. Such protection is able to provide a layer
Mineral wool density at least 50 kg / m. Cube laid with a layer of 100 mm. If a
The height of the beams is less than this magnitude, then they can fill lags. And the next
Material layer Place between lags. In order not to be created bridges
Cold, lags need to be located perpendicular to beams. Then the place of the junctions
Watches will be closed with the following layer.
- Soundproofing of inter-storey floors will be sufficient in
Cases of using matte from mineral or basalt cotton beds
Not less than 200 mm. At a density of 50 kg / mk. If the density of the material is higher, the layer
decreases proportionally.
Air and shock noise insulation index
Regulatory indicators of sound insulation of floors are registered in
such standards as SNiP 23-01-2003 "Noise Protection" and SNiP II-12-77 Protection against
noise. "
Detailed data displaying the specified level index
RW shock and air noise depending on the location of the overlap
Presented in the table.
Air and Impact Noise Insulation Index - Table
At the same time, sound insulation is considered sufficient if:
- RW is equal to or exceeding the regulatory value;
- LNW is equal to or below the normative value.
It should be known that the use of sound insulation
The material does not protect the room from sounds penetrating through the walls. therefore
Soundproofing walls need to be made additionally.

Competent person, judging by the reviews. Who already did, say the effect

mineral wool or mineral plates (thermal insulation plates from
mineral wool, for example, technonikol, technofas, rocklaight, ISOVER and
TD).
Acoustic insulation brand is chosen at your discretion,
The principle of all manufacturers is one. Varies size and density (thickness from
40 to 100 mm, density 30-140 kg / m3). Produced in the form of rolls or plates,
certain dimensions.
Attention!
Installation of wool is performed strictly in protective glasses and
Respirator.
The advantage of wool is excellent sound absorption, in particular,
Gas are well and partially medium frequencies. Here is the rule - than
thicker layer, the more it is able to absorb (meaning the spectrum of low
frequency). It should be understood that it is low frequencies are strongly transmitted through
Wooden overlaps and get rid of their penetration is very difficult. Why
So? Everything is simple - wooden floors have a low weight, and the tree performs in
The role of the resonator. In concrete floors to achieve sound insulation easier, in mind
Constructive features of the concrete slab and its properties.
However, if desired, you can significantly reduce the transfer
Noise through wood overlap. To do this, make a sound absorber,
Presenting a membrane type pie.
Soundwork membrane device
Pie is made of sheet material, as an option,
OSB or plywood (not thinner than 10 mm). Inside (between sheets) stacked
Soundproofer. As a sound absorber can be used:
- Mineral Wat (Minvata)
- Basalt fiber
- Madelita
- Building felt (technical)
If applying mineral wool material, then with density is not
Less than 30 kgm3 (the higher the density and thicker, the better).
Felt construction is characterized by high parameters
sound absorption, but inclined to water absorption and fire hazardous (although high quality
Antiseptic impregnation reduces the probability of fire, i.e. open does not burn
And tolets).
Construction (technical) felt - dense material from
Wool or synthetic fibers. Characteristics: Density - 10-80 kg / m3,
Thickness 5-40 mm, the width is different, varies from up to 2 meters,
thermal conductivity from 0.03 to 0.07 W / (M • K). Produced in rolls or in the form
cloth.
The sound absorber between the overlap and the membrane is not done
only for sound insulation, and more in order to pay off resonance,
arising between overlapping and membrane.

Soundproofing of wooden floors - the vibropodus-the achievement of the maximum soundproofing effect - the membrane (pie) should not be connected to the overlap, i.e. Must have an independent connection (attached to a separate profile at a distance of 10 cm from overlap, forming an airbag). It turns out a kind of suspended
ceiling.
Homemade vibrapropodvevoxic insulation pie is attached around the perimeter to the walls, and
In the middle of the beams only by means of amorticing mounts (elastic
Ceiling suspension), with a rare step, not less than meter. Vibropodves can be
Buy factory or make homemade vibrational suspension.
If the membrane is to fasten directly to the wooden beams of overlapping, the whole effect will be lost.
Principle of Technology - Synchronized Sound Wipes arising between
overlapping and membrane. It turns out, so to speak, the ceiling with resonant
absorber.
Soundproofing of wooden floors between floors - sound-absorbing membrane
An still possible device of such a design - Minvat is attached
grid or slats between beams of overlapping, and as a membrane (i.e. instead
HEE) Sew the ceiling of plywood or plasterboard. But they are attached not to the beams, but
Also independently (i.e. per walls), 3-5 cm below the overlap. With such
Device The role of the absorber will play minvat attached on the beams.
Soundproofing of Wooden Overlap Sand
The method is controversial. Time-consuming process, big weight and most
The main thing, the sound is partially extinguished, because The main resonance is transmitted by lags.
The principle of the device is shown in the photo.

Soundproofing overlapping sand
Noise isolation of sand overlaps
Of course, it all depends on the method of the device, as the masters advise, you need to fall asleep the sand between the lags and the draft floor, and not only between the beams of the overlap, and on top to mount the floating floor system.

Outcome
Soundproofing technology for wooden houses in
the difference from brick and concrete buildings has a number of features that
directly related to the design of the overlaps of their properties and sound conductors
characteristics. The methods described above will help isolate or significantly
reduce the penetration of sound waves between the floors in the frame cottages, and
Also in houses from a rounded log or bar.
