Two-layer – laminated parquets, that is, all multilayer parquets, carry the gradation of the “leader” among all types of parquets that are produced. The reasons are numerous and easily recognizable.
The current world production as well as statistical data published in numerous references in this field indicate that as much as 70% of all parquet floors are present in the multi-layer parquet flooring production, as opposed to other types of parquets. Two-layer parquets consist of two layers, depending on the total thickness of the parquet, the upper layer can be from 2 to 4 mm, the bottom layer is made of birch with a waterproof plywood plate, thickness from 8/10/12/15 mm. The total thickness of two-layer parquet from our production can be 10/14/16/19 mm, and the one we standardly produce is 10 and 14 mm thick. Two-layer parquet in relation to the classical (one-piece parquet) has a large and most significant characteristic, which is “not effervescing”, which means that there is no dissipation as with classical parquets, so there are no undesirable occurrences of fugue between parquet boards.
Large scale two-layer parquets remain compact and this is enabled by a multiplex birch plywood which is the substrate for this kind of parquet. The multiplex birch plywood substrate is cut sideways which give the parquetry great flexibility during assembly and also enables the adhesive to enter in the grooves and not allow for any axial or radial dilation which makes the parquet very stable.
Multiplex is a type of plywood made up of different types of wood, mainly softwood. Birch plywood is much sturdier and has a greater specific weight than fir wood or poplar wood which in and of itself makes it the best substrate when the demand is to place the parquet on a surface where there is floor heating. Multiplex is made by taking pieces of veneer, stacking them abeam while being glued with hot presses. Abeam basically means crossing the rings in the wood which keeps the substrate firm.
Two-layer parquet can be buffed which depends on the thickness of the upper wear and tear layer. It is known that each subsequent buffing and lacquering of the parquet within residential units is done only after 25-30 years, and with each buffing a maximum of 2-3/10 mm is removed so with a wear and tear layer, the parquet may be buffed at least 2 additional times.
Our parquets are oiled and lacquered via machines 2 to 4 times, depending on whether they were designed to be assembled in residential spaces or public ones/(restaurants, hotels, conference halls, schools, gymnasiums, libraries etc).
For a series of years now, the market has seen two-layer parquets with the thickness of the upper, wear and tear layer of 2mm, and practice has shown that the duration of this type of parquet is highly optimal and for many generations it is infinite.
Two layer massive parquet has greater humidity resistance than other multilayered and massive parquets due to its substrate, the birch multiplex humidity-resistant plywood. In case of possible spillage of water onto the parquet there is no significant malformations, that is there is no swelling of the surface due to moisture. Should this situation occur, one could easily fix the problem by replacing only the floor boards affected rather than the entire parquet surface.
There are many other advantages of the multi-layered over the classic, both aesthetically and functionally. We believe that much more should be mentioned positively from the point of view of ecology and forestry, in addition to the use of incomparably less rare hard wood that grows slowly, the production of multi-layer parquet has a very important role in nature conservation.
