Nowadays, many panel-type buildings that have a problem with sound insulation.This is especially true for unscrupulous developers who skimp on quality materials.Everybody decides this question in his own way.So many set ceilings with sound insulation.
- Any ceilings soundproof acoustic lower permeability areas.This is facilitated by the installation and features of the ordinary laws of physics.Therefore, this factor should be considered when planning the installation of stretch ceiling.
Any noise is transmitted by vibration.Sound vibrations are transmitted ceiling here and is transformed into sound waves, they are going vibration eardrums in humans.With proper installation of suspended ceiling prevents the transfer.
Noise suspended ceilings provided by the installation of a synthetic fabric down as a profile.Installation is performed as follows: between the ceiling and the film forms a layer of air, which is mounted and insulation.
Therefore, the materials used create a
Noise protection ceilings and provide additional sound insulation.This is because the desired properties of the web which is made of a polymeric material.
sound waves are transformed into light and almost imperceptible fluctuations due to the elasticity of the material web.Is reduced to such a level that the human ear can not perceive vibrations (recommended art. "How to make a payment of a stretch ceiling, and what it's for").
here should pay attention, insulation under the suspended ceiling has two functions, ie, helping to reduce noise fluctuations in both directions.Obstruction (ceiling-to-air-painting) is a barrier that reduces the spread of hesitation and a bottom-up and top-down.This property is recommended to use and noisy neighbors and lovers of silence.
stretch ceiling with noise insulation will help to forget about tapping the batteries.But it does not always work in new buildings, where you can even hear the sound of a fallen spoon neighbors.
Let's deal with this.For each type of noise to be applied his stuff.
All noise can be divided into two types:
- aircraft noise, they should include the sound generated by the recorder or the usual speech.At sufficiently powerful source they can be transmitted through walls and ceilings.
- structural noises which arise due to any mechanical action, for example by falling objects, or drilling.In this case, the creation of a sound wave occurs in the solid material.The solid velocity of sound in the 12-five times higher than in air.As a result, such a noise is heard much more.
reduce or eliminate the penetration of noise in two ways:
- Full soundproofing, which is performed on all the planes of space.This is a fairly efficient way, but requires significant costs.There should be a comprehensive work.In addition, the materials take the free space of the room.Therefore, it is good to use in a fairly large buildings.
- Partial insulation, which is performed with the installation of stretch ceiling.Here you can apply sound insulation boards, which are installed in the space between the blade and the coating.They are used in the construction of any widows ceilings.Here again, these activities, it is best to plan before installation.
Types of noise insulation materials
Soundproofing installed to absorb sound vibrations.
There are different types of sound insulation degree of rigidity:
- solid materials, which are produced using supenzirovannoy or granulated mineral wool.The composition is added to the porous aggregates: perlite, pumice and vermuklit.Such materials have a sound absorption coefficient of 0.5 and a weight of 300 to 400 kg / m3;
- Soft proofing materials, they are based will apply fiberglass or mineral wool or felt.Enjoy the sound absorption by a factor of 0,7-0,95.Weight 80-10 kg / m3;
- semi-rigid material is fiberglass or mineral products, made in the form of plates.When manufacturing is dominated by cellular structure.Enjoy the sound absorption by a factor of 0,5-0,75
Installation of sound insulation in stretch ceilings
installation works are carried out prior to installation soundproofing the ceiling.We recommend you read the article "Equipment for suspended ceilings - new technologies in business".
Terms installation soundproofing
for quality installation of sound insulation is required to fulfill certain requirements:
- impossible to do the installation of plates at once, you should give them a complete rest in a room for the installation within 24-x hours;
- adhesive or primer is applied on a dry surface;
- not store plates in areas where high humidity;
- to cut boards to use only special tools: circular saw, jigsaw, hacksaw.
to install a stretch ceiling with insulation you need: the very fabric stretched ceiling, plates for sound insulation, a drill, screws, glue, ladder.There are many soundproofing materials, but their installation is carried out before the installation of the ceiling paintings.
- layer insulation
- Tension ceilings
- profile wall
- decorative ribbon
- To start with all the rules are installing frame stretch ceiling;
- After that the plane of the ceiling should be treated with noise insulation materials.Fasten the plate with screws to the frame.When using plates of 1.2: 0.8 m. The screw used about 21, when using plates of 1.2: 0.45 is used for at least 15 screws;
- Laying slabs produced close.The joints of each layer should not coincide with the joints of the other row.Plates of the second row can be laid on the PVA glue, which can be applied by a point;
- joints treated filler plates;
- As for soundproofing can use special inks that are applied to the surface of the ceiling.This is a relatively new product that has recently appeared on the market, but has won her fans.The structure of a paint add special components for sound insulation;
choice of material for sound insulation ceiling
Noise stretch ceiling in a room with a lot of well-performed using an acoustic ceiling when installing sound-absorbing mineral wool.This design works well and prevents the penetration of outside noise.Even when entering through the walls and floor, it will be absorbed by the ceiling.
- Noise Tension ceilings are best carried out with the use of panels of mineral basalt basis.Such material is easy to install, for example, in contrast to the panels made on the basis of glass fibers, which can cause skin rashes and itching;
- All great demand for polypropylene, polystyrene.They are perfect when space is limited between the ceiling and the plane of the coating.Such material is simply glued to the ceiling, and to increase the sound insulation can be plastered;
- To design a good sound absorption, use porous or fibrous materials.To put it simply, it has to be blown.For example, polystyrene is not blown material, but has a honeycomb structure.It has a low coefficient of insulation,
- now in vogue and in demand begins to heat-insulating liquid material.He not only absorbs sound, but also serves as insulation.It protects against moisture and condensation.It can be used in rooms with high humidity;
When soundproofing a stretch ceiling installation is often used several layers.This greatly improves the sound insulation structure.
Warning: When working on the insulation should be remembered that during the installation should be carried out following nuances:
- Do tightness in the conduct of the work of the whole structure;
- In choosing the material should be clearly understood what the impact of noise you want to remove.We talked about this before.According to this definition, it is necessary and to select appropriate material;
- sure to wire and insulation of all utilities (heating pipes, ventilation, etc.), Not through the quality seal of these systems is perfectly transmitted sound.To do this often use sound insulation material for lining ducts.
As a result of the above, you can see, you can improve sound insulation by installing a suspended ceiling in the construction of a noise insulation or soundproofing.Such products are present in large quantities in the retail trade.
But if there is high penetration of ambient noise in the room, then it is necessary to resort to the help of experts in the issue of architectural acoustics.To help pick up the security system just for your room.If you do not plan to independently establish the suspended ceiling, it is useful to you the article "The contract for the installation of suspended ceilings - doing the right thing."
