Interior design ideas

The parquet board is a progressive building material, it has thought up as replacement of a massive parquet board and to a piece parquet with the purpose of its cost reduction. The reasonable overlapping of firm and concerning soft breeds the wood, stable structure, easy stacking, and long service life - enable a parquet board to take a worthy place in the market of flour coverings.
In a multilayered parquet board valuable breeds of trees are used only in the uppermost layer which has the 3-4 mm thickness, other layers are carried out from less valuable breeds, more often are made of pine and fur-tree. Such design of a parquet board allows not only to lower its cost and to reduce the charge of wood of valuable breeds of trees, but also to correct some lacks inherent in a piece parquet and a parquet from a massive board. The matter is that the condition of parquet floors strongly depends on temperature and humidity conditions of the premises. So, for example, the change in humidity on 10 % leads to increase in the size of parquet from a file up to 1 square meter in width.
It is necessary to support humidity of 60 % and temperature not below 18????. As a rule, such conditions exist in city apartments only in the summer when the central heating does not work. In the winter relative humidity in an apartment often does not exceed 50 %. Any temperature and humidity conditions changes lead to piece parquet and a massive parquet board deformation.
Parquet board Floors are considerably less sensitive to the temperature and humidity conditions. Such effect is reached owing to perpendicular accommodation of layers of wood in a multilayered package. The top layer from valuable breeds of wood is placed with fibers along the long party of a board. Fibers of an average layer are placed across fibers top, and the bottom layer is pasted with fibers across previous one. In case of humidity changes wood changes the sizes basically in a cross-section direction. Layers with a perpendicular arrangement of fibers do not allow extending to the neighbors, which does not allow extending all design. Therefore the parquet board in much resistant to any humidity changes.
On the structure the top layer of a parquet board can be made in the form of a continuous plate, or is stuck together from several boards. To this attribute the parquet board can be divided into one-strip, two-way and three-lane parquet. The first type imitates parquet from the massive board, two second one- a piece parquet. The average layer is usually made of pine a board, the bottom layer is made of plywood.
