How to make noise insulation of the ceiling with your own hands?

In today's world it is extremely important to do it rightorganize rest and sleep. As a rule, people often face the problem of poor soundproofing of their living space, as a result of which all plans become simply unfeasible.Scheme of ceiling insulationScheme of the ceiling soundproofing device.This problem concerns both old houses and new multi-storey buildings. Moreover, even in your own home, the lack of good sound insulation can negatively affect your emotional state. The key role in insulation issues is played by the sound insulation of the ceiling. But how to do sound insulation correctly? Unlike walls, the ceiling is able to conduct noise best. This is especially true for apartments. After all, the presence of restless residents living on the floor above can spoil the mood of even the calmest person.

Material selection: sound insulation and sound absorption

Soundproofing of the ceiling in the room shouldbe carried out at the stage of repair. After all, it is difficult to do this later, since you will have to dismantle the finishing and do everything again. But, before getting down to work, you must first choose the material that is best suited for insulation.Table of materials for sound insulation.So, experts distinguish two types of material. One is designed to absorb sounds, and the other - to insulate against sounds. Therefore, it is advisable to learn the main differences between them. Here, both external characteristics and operational ones take place. Materials that are designed for soundproofing a room are usually very heavy in weight. Due to their high density, they should reliably reflect sound waves, as a result of which the sound simply will not penetrate into the room. These materials usually do not have any pores in their composition, but their thickness can vary significantly. Sound absorption materials include all durable building structures, such as plasterboard sheets, concrete slabs, bricks, cinder blocks, plywood and concrete structures of various types. The thicker the material, the better it will reflect sound waves. Sound absorption materials have many pores of different sizes in their composition, due to which sound is absorbed and, accordingly, its penetration into the room is prevented. Usually these are materials from different types of fibers, where absorption occurs in the pores due to friction of sound waves against them. Sound-absorbing materials usually include all types of slabs: fiberglass, basalt, mineral and others. The thickness of the slabs can also be different. And which thickness is best to choose depends on the ceiling design and the required degree of insulation. Here, to a large extent, the degree of efficiency will depend not on the thickness of the material, but on its porosity and the quality of the fibers used.Scheme of installation of sound insulation on a suspended ceiling.Another relatively new material for soundproofing is a covering based on natural cork. This material is irreplaceable in case of mechanical noise, which occurs mainly on the floor. But you will not achieve good protection from other sounds. Therefore, it is best to use cork for neighbors upstairs to insulate the floor. Or for you in your house to insulate the lower floor from the upper one. So, you have learned the features. Now it's time to decide which material is best to choose. And here, many owners make the same mistake in most cases, giving preference exclusively to insulation or absorption. But physics teaches the opposite: during insulation, acoustic waves are swayed, which can create secondary noise. And it can only be removed through proper absorption. Conclusion - use both sound insulating and absorbing material at the same time. In this case, there should be insulating layers at the bottom and top, and sound-absorbing fiber in the middle. This type of insulation will be almost ideal. It does not matter at all what types of materials are chosen for the layers. Here you can focus exclusively on the future ceiling design and cost.

Surface preparation of the ceiling

And now, actually, about ceiling insulation.You have chosen the material, now it is time to start preparing the surfaces. To do this, first dismantle the old covering from the ceiling and remove the crumbling plaster and putty, do not spare them. After all, sooner or later they will crumble, which will negatively affect your repair.Tools for soundproofing installation.Now, remove any dust from the ceiling with a soft brush and coat the surface well with primer. After drying, start filling in holes and cracks. It is better to do this with a good putty. But if there are too many deformations, you can also use concrete mortar. But in the end, the ceiling should be puttied in any case. And when the putty dries, apply another control layer of primer. Then proceed to finishing the ceiling to achieve noise protection. As a rule, it is customary to distinguish two types of this kind of finishing: frameless and frame. It is best to give preference to frame finishing, as it is more reliable and durable. Frame soundproofing of the ceiling from penetrating noise is the presence of a special frame, for which the layers of materials are attached. There are three main parameters that ultimately determine the quality of such work: the correctness of the technology, the reliability of the layers and the choice of high-quality material. And if the last parameter has already been discussed above, the first two still need to be considered in more detail. Return to the table of contents</a>

Materials and Tools

Before getting down to business directlyработу, нужно запастись нужным количеством материалов и всевозможными инструментами. Также неплохо пригласить помощника, так как работать с потолком одному довольно тяжело. Итак, для работы вам необходимо иметь:

  • building level;
  • metal profiles;
  • plasterboard sheets;
  • pencil and tape measure for markings;
  • building knife for metal;
  • rubber gaskets;
  • screwdriver or punch;
  • dowels, screws and screws;
  • fibrous material for noise absorption;
  • sealant based on acrylic (you can use a special putty).

In this version of the work it is necessary to consider,how to make soundproofing, where any fibrous material can be used to absorb sound. For reflection, you need to use plasterboard in the lower part of the ceiling. The upper part of the ceiling will remain untouched, since the concrete slab with sealed cracks and holes will serve as a kind of layer for reverse reflection. Return to the table of contents</a>

Mounting the frame

Ceiling frame diagram.So, how to soundproof a ceiling with your own hands? All work begins with assembling the frame. As a rule, any metal frame has instructions, according to which it is necessary to carry out the assembly. At the same time, try to make each connection using rubber gaskets. This will make the fastening more reliable. After assembly, you need to attach the frame to the ceiling. This is done using self-tapping screws with dowels and a hammer drill. Just take care of the marking in advance so that you do not have to guess during work where it is better to make the fastening. It is advisable to make fastenings at least every 40-50 cm. At the same time, keep in mind that the frame can be assembled in advance, after which it is attached to the ceiling, or gradually assembled directly on the surface of the ceiling itself. Here you have the right to choose a more convenient option for yourself. When attaching the frame, you need to pay special attention to the structures along the perimeter of the ceiling near the wall. The screws should be the largest and most reliable. Some craftsmen advise to also carry out additional fastening to the walls using small metal corners. This method will not only allow the frame to be better fixed, but will also prevent it from deforming in the future due to temperature and humidity changes. Just don't forget to restore the top of the wall in advance, as it will be problematic to do this later. Return to contents</a>

Formation of pie

Now you need to make soundproofing in the piefrom fiber boards. To do this, measure the distances between the planks in the frame, then cut out the necessary pieces of fiber boards (they must be larger than these gaps so that they can be pushed into the frame tightly enough). Then they are pushed tightly into the frame. You can make additional fixation to the ceiling at the corners using the substance "liquid nails". After this, it's time to start equipping the reflective layer, which will be drywall. Markings are made on the sheets at the attachment points, then the material is placed on the screws, securing it in the frame. The screw heads should be recessed so that their level coincides with the level of the drywall. But you can also plant them 1-2 mm deeper. Immediately check the evenness of the structure with a building level. In case of unevenness, try to correct the shortcomings by more or less deep recessing. So, now you know how to make soundproofing on the ceiling. Now all that remains is to fill the gaps between the sheets of drywall with putty or sealant, as well as between the drywall and the walls. If you have done everything correctly, the neighbors upstairs will not bother you anymore.
