Floors, in addition to a good appearance and strength, must have minimal sound conductivity. It can also be added to the main qualities that the floor should be wear -resistant, warm, smooth, but not slippery, silent when walking, not distinguishing dust, resistant to chemicals and not to be pushed by strokes or from static loads.
This type of flooring is a base with a glued intermediate layer and the upper, decorative layer with a certain pattern of strips. For the manufacture of the base, they usually use spruce or pine plywood. The second intermediate layer is made of high density of wood -fiber plate (HDF) or glued coniferous wood. This layer is often called stabilizing. It is laid perpendicular to the base to avoid the voltage between the components of the parquet board and ensure the strength of the flooring. Play and crests or castle joints are made in this layer to simplify the assembly. For the last upper (working) layer, either a veneer up to 2.5 mm thick, or a bar (lamellas) with a thickness of up to 4 mm is used.
Valuable wood rocks choose the material. The most traditional and exotic of them: walnut, oak, ash, beech, European maple, cherry, African Iroko, Wenge, Dussia. The thicker upper board will last longer. It is believed that such a property as the hardness of wood does not play a decisive role for a parquet board. To a greater extent, the decorative of the coating can be affected by the ability of a tree to change color under the influence of ultraviolet radiation. And if the beech, maple or ash virtually do not change over time, then exotic breeds: Dussia, Irooko, Wenge, on the contrary, quickly oxidize and darken. The cover pattern will remain unchanged.
The selection of material (for one breed) of the upper layer is carried out according to color, texture, variegation, as well as knotty and sapwood (separate lighter fragments). The most expensive (elite or suite) group is selected from the rails of the radial sawing and carefully disassemble the color and structure, from which the flooring has an even color. For the group, the standard is used simultaneously radial and tangential cuts, with small knots. Which gives the coating a more colorful look. In the third group, various types of sawing, drawings are used, preserving the service life of the same as a suite or standard. For some interiors, a more “live” parquet board is more suitable than the restrained material of the elites of the group.
The parquet board has many varieties in the wood species and the drawing of its constituent elements. This is environmentally friendly, natural, warm material. The possibility of fast installation, thanks to modern castles, ease of care, moisture resistance, decorativeness of the parquet board attract customers.
