Why multi layer composite solid wood is more expensive than three layer composite solid wood

I'm sure that the salesman told you that the milligram standard dropout unit must be cubic meters, because so far no milligram L has been found, if it is a cubic meter, converted into a common milligram per liter of the detection unit, the volume difference is ten times, and, if from the salesman's words just now, the strengthening process is to glue the wooden paddles together, three layers of solid wood only need to be glued in the place where the three layers are connected, that is not much less glue than strengthening, of course, it still depends on his testing standards, geothermal speaking, In addition to solid wood flooring, as long as it meets the national standard of solid wood composite, reinforced composite is suitable for geothermal heating, the thermal conductivity of laminate flooring will be better, and the thermal insulation performance of solid wood composite is better, see which is more suitable for you, if you choose solid wood composite, it is best to choose three layers of solid wood, first of all, from the environmental protection point of view, three layers of glue should be used less than multiple layers, from the thermal conductivity, the middle layer of three layers of solid wood on the market should be left with expansion joints of thermal expansion and contraction, and also use heat conduction.

Three-layer solid wood composite is good.

Flooring according to the price from low to high: pure composite flooring, the advantage is that it is cheap, easy to take care of, and there is a lot of room for selection of patterns and colors (because it is made manually); Disadvantages: poor comfort (because there is no keel, very hard), the effect of specialization is unnatural, the most important thing is that it is not very environmentally friendly (mainly made of wood surface with glue with high pressure, some people also call it a high-density board, a large amount of glue is the source of pollution). >>>More

I have already sent you a message, and I would like to add that the three-layer solid wood of the Holy Elephant Kang tree is all 15 mm, the effect is good, the quality is very stable, such a thickness will not affect the thermal conductivity effect, the floor mat of the geothermal heat, it is better to choose the kind that is not tin foil, which affects the thermal conductivity!!

1.Both three-layer and multi-layer hardwood flooring can be used for underfloor heating, and in terms of stability, multi-layer is slightly better than three-layer. >>>More

There is no difference, it is the difference in the number of layers!
