I want to buy multi layer solid wood flooring, how to choose the best one? Help!

You can choose from the following aspects:

The processing size should be precise.

The processing error of the wooden floor should be small, the geometric size should be regular, whether the slats are flat, especially the width direction and the tenon and groove size of the tenon and tenon are more important, generally below plus or minus millimeters.

The board surface should be flat and smooth.

There are no obvious knife marks on the front, and a little trace of missing planing or sawing is allowed on the reverse side, and the vertebral groove groove should be properly tightened and smooth, without blockage and no obvious gap.

Wood defects should be limited.

Genuine straight lines are obvious and parallel, and reach "ten no", no knots, no insect eyes, no decay, no blunt edges, no cracks, no distortion, no twills, etc. In particular, there should be no blunt edges, so as not to affect the pavement.

The wood must be dried.

In addition to the inherent thermal expansion and cold contraction characteristics of the object, wood also has the characteristics of wet expansion and dry contraction. Therefore, the drying process in the production process of wood flooring is an extremely important process, and the quality of the treatment has a great impact on the quality of the floor. The moisture content of wooden flooring is generally required to be controlled below 15%, and 8% to 12% is the best.

Vary. The type of wooden flooring is selected according to the economic conditions, the size of the room, the height of the floor, and the length of the stay. Strip flooring and parquet flooring can be laid without glue, which is easy to disassemble and assemble when relocating; Short strip parquet flooring is generally laid by adhesive method, but it is difficult to disassemble and assemble.

1) Decors.

Place the floor in a bright place to see if there are cracks, dead knots, pinholes, knots, mildew and other defects on the surface, but you can't be too strict about small slipknots and color differences, because this is the natural property of wood.

2) Paint. Hold the lacquer board in your hand and place it obliquely in a bright place, and look at the end of the board to see whether the paint film is plump and uniform, whether there is a wavy shape indentation, etc.

3) Physical and chemical indicators.

Ask the salesperson for it, and then compare it with the national physical and chemical indicators.

4) Machining accuracy.

Floor processing is good or bad, directly affecting the quality of laying, usually in the same packaging box to take more than 5 pieces of floor on the glass table or flat ground, with the hand to pat the tenon groove match, and then touch with the hand, feel whether it is flat, and then use the eyes to see whether the tenon and groove combination is seam, can not be too tight, because if it is too tight, the humidity increases slightly during installation, and it is difficult to match when the tenon and groove are combined.

5) Specifications. IF IT IS USED FOR UNDERFLOOR HEATING, IT IS BETTER TO USE A THICKNESS OF 12MM FOR MULTI-LAYER SOLID WOOD FLOORING.

6) Three guarantees of inspection product packaging, manufacturers, trademarks and quality inspection, guarantee commitment. Usually, the country of formal products clearly stipulates that there should be a complete set of product information, including manufacturers, brands, product standards, inspection grades, instructions for use, after-sales service and other information, and the information is complete with products, indicating that the manufacturer is a regular enterprise with a certain scale, even if there is a problem with consumers, it is well documented.

The development of multi-layer solid wood has developed from the beginning of solid wood composite (base material plus solid wood surface layer) to three-layer solid wood, to the current popular multi-layer (5 layers, 9 layers, 11 layers, 12 layers, etc.) criss-cross lamination, with the purpose of further increasing the stability of the floor; Therefore, multi-layer solid wood is a stable and strong floor than reinforced and single solid wood, not afraid of water, and it is also the best choice to do geothermal heating.

There are two kinds of multi-layer solid wood, one is the substrate made of nine-layer synthetic plywood, the common solid wood composite of domestic flooring, and the other is the popular three-layer solid wood in the European market. However, at present, three-layer solid wood has just started in China, and the European market is quite popular.
