Laying a laminate is quite simple, with this in mindobservance of the basis and rules of installation of this type of flooring will be able to cope and beginner. But how to eliminate the creak of a laminate, which often not only causes irritation, but can also be a harbinger of the appearance of more serious problems, can be understood only by finding the cause. 
Laminate creaks are common causes: irregularities on the surface of the base, lack of compensation gap, moisture drop. For a long time already laminate has become quite a democratic type of floor covering, possessing a large number of advantages. In addition to price and ease of installation, this material (depending on the class) has high strength and performance characteristics. A wide range of colors, imitation of natural wood or other materials allow its use in interiors, designed in almost any style. But quite often after laying a characteristic creak appears, which can have a clear localization or spread throughout the floor. Most often it is believed that the laminate creaks after laying due to improperly mounted installation, this often has a rationale, but not always. There are a lot of reasons for this, they can be caused both by violations during the laying of the floor covering, and are operational, appearing after some time defects.
The main causes of squeak laminate due to a violation of the installation technology
Poorly leveled sub-floor - basicthe cause of extraneous sounds after installation. It should be borne in mind that it is necessary, if not on an ideal, then necessarily an even base; one cannot hope that the substrate will save the situation, even if you choose a material thicker than required. During operation, it will settle down, and especially strongly in places experiencing the greatest stress. Laminate creaking may appear very soon. If the floor has minor imperfections, you can fix them with a thin layer of self-leveling compound. But when the condition of the base is critical, it will be necessary to perform a full-fledged screed, other methods for solving the problem will not work. In addition to the fact that the base of the floor must be flat, it must be clean - without sand, small debris and even dust. If the cause of the squeak is of this nature and is observed only in one or two places, then this area should be disassembled, the cause should be removed, that is, the remains of construction or other debris, and put back. But if the floor creaks over the entire area, then you will need to disassemble the coating (remembering to number the parts), thoroughly clean the base and, most likely, replace the substrate. Sometimes, for greater effect, some masters advise to lay a layer of plastic film on the screed, and on top - the substrate. If the base is even, then it makes no sense to lay a thicker, but soft underlay under the laminate. Heat will not increase from it, but problems will appear - the floor will begin to creak over time (or immediately). And if the base has some irregularities, then all the more it will not save the situation, on the contrary, it will aggravate it. The optimum substrate thickness is only 2-3 mm.

The voltage in the junction joints and the dimensions of the gaps
Another reason for the cracking of the coating -this is the absence of a gap between the flooring and the wall along the perimeter of the room. When laying a laminate, it is necessary to observe the condition - leave a mandatory gap between it and the wall within 0,7-1 cm, and if the area of the room is large, then up to 1,5-2 cm. When this condition is not observed, immediately after laying a creak appears. This gap is necessary in order for the laminate to be disposed of and in the future, during operation, no tension was created in the connecting locks. Solve the problem in this case quite easily, you just need to trim the extreme parts to the desired width and close the gap again with a plinth, while at the same time controlling the force of its pressing - it should be tightened tightly, but without much effort. If the laminate is creaking around the door, then the reason may be due to the fact that the clypeus strongly presses on it, then it should be removed and a little pruned. It is very important, when performing the installation, to give the laminate a few days to lie down, and the gaps of the skirting boards should be closed after this. In this case, you can immediately see the problem and fix it. 
Significant jumps in humidity and temperature inThe room can also cause the creaking of the laminate. But sometimes the creak of the laminate is not a signal that the installation was done incorrectly. Often immediately after laying because of a certain tension in the joints, but with the observance of the entire technology, this phenomenon is perfectly normal and lasts for 1-3 months. This feature of this behavior of the laminate has an explanation - the floor during the time is finally straightened out, adapts to the operating conditions, such as the humidity of the room and the mechanical loads that affect it. Often, especially in open interiors, the complete absence of interior thresholds is assumed. But for laminate it is one more reason to creak. Therefore, if the space is large enough, then we should not neglect the possibility of fixing the material, otherwise it will not be possible to get rid of the squeak. But if after this time the problem does not disappear, then the reason for the creaking is different, except for cases when cheap and poor-quality material was purchased for the floor. His creak, most likely, will be permanent. This is due to the fact that low-cost laminate types have very poor quality joints. And to solve the problem in this case is easy and difficult at the same time: you should buy a new high-quality material, dismantle the old floor covering and lay a new one. Back to contents</a>
Laminate scraped in use
Laminate Lock: the main place of origin of the creaking. Even with all the rules of installation, operation and care, the laminate can begin to creak after a while. This phenomenon can become permanent or manifest only occasionally. In this case, there are usually two reasons. The first and the main - the temperature and humidity regime. After eliminating the cause, the scratch of the laminate itself passes. But if it increases, perhaps the cause of the shrinkage of the house - this phenomenon is often observed in new buildings, about a year later, or in old houses. This can be a signal that there is a destruction of the structure with a possible deformation of the bearing structures. As a floor covering for warm floors, laminate is quite suitable. But in order not to bring the situation before the appearance of the creaking, it is necessary to observe some rules that are similar to those required for the device and the exploitation of warm floors in cases where parquet is used as a floor covering. You can not allow a sudden rise in temperature. At the beginning of the operation or season, it is recommended to raise it no more than 1 ° C every day. In this case, situations involving sudden fluctuations in temperature and humidity in the room should be avoided.
