Soundproofing the ceiling for plasterboard in the apartment: technology, materials

Housing in multi-storey buildings is characterized by poor sound insulation. Any loud sounds behind the wall are audible to all neighbors. Many are trying to improve sound insulation. You can do this for all surfaces in the dwelling or only for one, if the area is small and every square meter is expensive. Soundproofing the ceiling for plasterboard is performed using various materials. A certain work order must be followed. It is worthwhile to understand this issue in more detail.

Do-it-yourself ceiling soundproofing technology

The process begins with the selection of a suitable material. There are several types of them on the market. Each has certain characteristics that are worth considering. Then they select the necessary equipment, carry out surface preparation and proceed to the main stage.

Tools for the job

The material planned to be used for sound insulation is prepared in advance. You will need a tape measure, drywall and acrylic sealant. You will also need scissors that can cut metal, metal profiles, high-quality rubber pads and a level. It is recommended to use self-tapping screws for fastening. Additionally, you need a puncher.

Ceiling preparation for finishing

This is an important step in soundproofing. It is necessary to get rid of all cracks and cracks, even small ones. Sound will penetrate the room through them, which will reduce the quality of insulation. Defects are easy to fix with plaster. But it is recommended to start by removing the old cladding. Then they clean the surface from dust and start plastering.

Reference. The quality of the noise insulation depends on how well the base is prepared. This stage cannot be neglected.

You should start applying the markings. A professional laser device may be used if available. Plumb lines and tape measure will also work. Only then do they begin to assemble the aluminum structure.

When working with the frame base, use pieces of sealing tape. This will reduce vibration noise almost completely.

Collecting aluminum structure

It is recommended to collect it, relying on the markings made earlier. The distance between the profiles should be no more than the dimensions of the boards of the selected insulation raw materials. Otherwise, it will not be tightly fixed, it will begin to fall out, and the noise will not be reduced. When assembling the frame, it is important to check how securely all its elements are held. When the structure is ready, wiring and other necessary communications can be threaded into it.

Fixing insulating materials

When assembling the frame, the raw materials used for the insulation should be taken into account. Its dimensions must match the erected structure. Then the frame base is attached to the surface. Then you can start filling it with an insulating product. It is important that it holds on tightly, does not fall, does not crumble.

Plasterboard installation

When the insulating material has filled the frame, they begin to fix the drywall - from the far corner of the room. The slab is applied to the ceiling, checked if it is suitable in size, and fixed. For this, self-tapping screws are used. For one drywall sheet, it is recommended to take about 50 pieces of fasteners - for greater structural reliability.

When the first sheet is fixed, the further direction of the canvas is chosen independently. Seams should be kept to a minimum. Otherwise, sound will come through them. When the work is completed, all joints are sealed with putty or sealant for additional insulation.

Filling the voids

It has already been noted that all joints must be additionally covered with a suitable compound in order to improve the insulating properties of the created structure. You can also use the acoustic options to reduce the penetration of sounds into the room from the outside.

Only an integrated approach will allow you to get high-quality protection.

Methods and materials for sound insulation, their characteristics

It was noted that there are several types of insulation products. Each has certain nuances that affect the final choice. It also depends on how good the sound insulation will turn out.

Mineral wool

The material is quite soft, which allows it to absorb noise well. The advantage of using it is its low cost. This is the best way to carry out soundproofing economically. Among other types of products for similar purposes, this is the cheapest. Installation of mineral wool is simple. It is sold in slabs, so it is enough to fix them on the structure and make sure that everything is held securely.

Extruded polystyrene foam

It has good performance. Reduces the penetration of sounds from the outside into the room and allows you to retain heat. Choosing this product, you can solve several issues at once. It is important that special glue must be used to fix the expanded polystyrene. There are many analogs of the product, but it is not worth replacing it. It is distinguished by good density and hardness. Therefore, it is he, and not similar options, that is able to qualitatively reduce the noise level.

Soundproof membranes

This is a special membrane lining. Differs in small thickness and good properties. It is important that during installation it is necessary to mount it not on the frame itself, but under it. It protects against vibrations. Due to its subtlety, it will not only eliminate unnecessary noise, but also will not "take" the height of the ceiling.

Vibration suspensions as a way to improve sound insulation

This device is popular and is used more often than other types. The design is quite simple, but it has good sound insulation properties. Vibration suspensions differ in appearance, characteristics and cost. Their variety allows you to choose the right option for a specific ceiling and conditions.

Natural fiber

Basalt wool, which is based on natural raw materials, can be used. The structure of the product is fibrous, which allows it to qualitatively isolate the space from noise. Like mineral wool, this material is sold in slabs. This simplifies installation work. Natural fiber also allows air to pass through well, which prevents mold from developing on the surface. It belongs to the highest quality options for noise protection. Can be used not only inside the room, but also outside.

Liquid insulation

The essence of the method is to apply a special composition to the ceiling in the form of paint. Even a single layer can reduce the amount of noise penetrating inside and retain heat. The advantage is that there is no need to construct and fix the frame. A great option for apartments with low ceilings, where every centimeter is important.

Soundproofing can be done by yourself. It is necessary to choose the right material, prepare the surface and carry out a high-quality installation. Before work, you should take into account the characteristics of the premises, the desired result and financial capabilities.
