How to solve the sound of the floor?

Want to make no noise floor, must first find out the cause of the noise floor, in general, according to wooden floor shop outfit, acceptance and use standard (GB/T20238-2006), the roughness of the ground for 5 mm / 2 m or less, after the installation of wooden keel of flatness for 3 mm / 2 m or less, the actual surface roughness is very difficult to meet the requirements, installation personnel in the bottom of the wooden keel and gaskets, have a plenty of gaskets no padded or no cushion flat, the floor is installed, the part of the floor position not fully contact with the wooden keel, noise occurs when people walking on the WPC floor. This is the case when the installation is immediate and is local. Here are some reasons why the floor is humming:

The distance of wooden keel should not be too far, do not exceed 350mm
Some wooden keel distance 450 mm or even further, when the weight of the larger staff one foot stepped on a single floor, the floor down large deflection, the side friction and the adjacent floor, floor produces noise. If this is the case, the single floor will ring, the floor will not ring, and it will happen after installation.

The water content of wooden keel is different
In some areas, the wooden keel does not carry out dry, at random in the open air, the water content of the wooden keel is different. In the same batch of the wooden keel, some water content is about 10%, some up to more than 25%. Even the installation personnel find wooden keel is flat, the floor is installed temporarily may not ring, in use process, the moisture content of wooden keel rebalancing, can appear rugged, walking on the floor can produce noise. The feature is: it doesn't ring when installed, and it goes off after a period of use. There is not much noise. Beijing area big brands use to dry out the wooden keel, also some dealers to play wooden keel, temporarily not to install the floor, place a week or so, levelling pavement again, can reduce the probability of such a problem.

Improper moisture-proof measures
Floor installation time, due to improper moisture-proof measures, tile shape deformation after the floor be affected with damp be affected with damp, tile shape deformation more serious when the wood plastic floor does not produce noise, because the floor bloated, between each other, is tight, when people walk around on the floor, the floor will not up and down movement, so it won't produce the mutual friction and noise. The main complaint of consumers is the floor deformation or cracks in the board. If the groundwater running after, the moisture of the floor continues to drop to normal, the gap between the floor, the floor tile shape does not completely disappear, the regular floor on the top of the wooden keel teeter-totter, people walking on the floor will be everywhere.

This is a condition that first goes through a wet period before it enters the dry period and occurs mostly in the northern winter. In addition, there are a relatively special cases, in the process of the floor installation, although the moistureproof not ready, because of the groundwater is not very high, the floor appears a slight bulge and mild clay shape deformation, even has not felt the floor on the vision has the bulge and clay shape deformation. In fact, the floor has a slight gap between the wooden keel, and when people step on the floor, they make a noise. The characteristic of this kind of problem is that after the floor is installed very short time will produce sound, and more and more, heavier and heavier. The shortest time, the next day will ring. Some people also often ask: step on the same floor, the first foot will sound, after a few feet will not ring, after a while to re-tread the place will ring, this is why? Actually very simple, we repeatedly step on the same place, the floor already with the wooden keel close contact, the floor does not move up and down space, the floor also does not ring. When we step on another place, the floor here is raised again, with the wooden keel has clearance, so, again tread this place again can produce a noise.

Reserve gaps
The real wood floor has the characteristics of the drying shrinkage is wet bilge, when installing the floor must be according to the actual moisture content of floor, wood drying shrinkage coefficient, the region of the gaps between the equilibrium moisture content article reasonable reserve the floor. If the reserved gap between floor installs the floor bar, floor slight extrusion, individual place slightly raised, have space between the floor and wooden keel or bedding, people walking on the floor to produce noise. According to the wood floor shop outfit, acceptance and use of the standard (GB/T20238-2006), real wood floor is installed, the cushion on the wooden keel, and on the cushion layer spread moistureproof film, can effectively control the external environment impact on the floor, to prevent the floor tile shape deformation. Floor or man-made board, with wool pad often many installation personnel in the use of plywood or joinery board, do cushion layer, the whole will find wood or plywood shop is on the top of the wooden keel, and didn't leave a gap between the cushion, cushion the drum after being affected with damp be affected with damp, cause since the floor drum, also can produce noise.

The floor under the floor should be cut into dimensions not greater than 600 x 600mm, each layer should be left not less than the 5mm gap. Then it is covered with the moisture-proof membrane on the cushion layer, the floor is installed on the moisture-proof membrane, and the gap is reserved scientifically and reasonably. You can do most of the noise.

To sum up, various reasons can cause the floor to make a sound. In order to avoid the appearance of the sound, choose the correct installation method, do well on the floor moistureproof treatment, reasonable reserve the gap. The sound of the floor is very difficult to deal with, so it is very important to take active precautions. Of course, it is also very easy to solve the problem after finding out the reason.
