A parquet floor is not only versatile and visually appealing, but also convinces by its durability.
The decisive criterion for the service life is the thickness of the parquet.
An overview of the commercialstrengths and the different structure of parquet floors can be found in this article.
In which thicknesses is parquet available?
The thickness of the parquet depends on the type of parquet.
Parquet is generally available in two versions, which differ fundamentallyin their structure – and therefore in their actual thickness :
Solid parquet (one-layer parquet)
The classic solid parquet (also single-layer parquet) consists of a layer of solid wood, which is first laid mostly in the raw state fully glued and then sanded and surface treated.
On the one hand, the installation of solid parquet is relatively complex and time-consuming, as the floor is only ready for use and walkable after several steps. On the other hand, the thickness of the solid parquet also ensures particularly high resistance and durability.
Solid parquet is available in different thicknesses between 8 and 23 mm.
Due to its thickness, it can be sanded several timesin the course of renovation sanding.
Assuming that parquet is in need of renovation approximately every 10 to 15 years due to wear and damage and that approx. 0.3 to 0.5 mm of the parquet surface are removed per grinding process, solid parquet has a service life of several decades.
The most common variants of solid parquet floors and their strengths Are:
- Bar parquet:
14 to 23 mm, can be sanded 5 – 7 times
- Ship’s floor:
14 to 23 mm, can be sanded 5 – 7 times
- Mosaic parquet:
8 to 10 mm, can be sanded 4 – 5 times
6 to 15 mm (standard: 10 mm), can be sanded 4 – 5 times
- Table parquet:
approx. 10 mm (sometimes up to 20 mm), can be sanded 4 – 5 times
Prefabricated parquet (multi-layer parquet)
In contrast to the solid parquet, finished or multi-layer parquet consists of several layers glued together.
It is already ready for installation and is surface-treated with a layer sealed by oil or varnish, so that it can be walked immediately after installation.
Prefabricated parquet is available as 2-layer or 3-layer parquet. 2-layer parquet consists of a support material made of wood composite panels or cheap wood, which is glued with a useful layer of high-quality real wood.
3-layer parquet in addition contains a – also made of wood or wood composites – counter, which makes the floor even more stable.
Decisive for the quality of prefabricated parquet is the useful layer:
This consists of different types of wood and should have a thickness of at least 2.5 mm.
The principle applies:
The higher the thickness of the useful layer of the parquet, the higher the quality of the floor and the higher its service life.
The total thickness of the parquet is therefore made up of the thickness of the of the carrier material and the useful layer. Commercially available prefabricated parquet has the following common strengths:
Total thickness 10 to 16 mm, useful layer 3 to 6 mm, can be sanded 2 – 3 times
Total thickness 10 to 25 mm, useful layer 3 to 8 mm, can be sanded 2 – 4 times
Special shape: veneer parquet
Veneer parquet is considered a special form of parquet flooring, as it combines the special features of wood and laminate floors:
Precious wood veneers with a doctored, multi-coated surface are glued with water-resistant HDF support plates.
The total thickness of veneer parquet is also between 10 and 23 mm. Unlike the classic prefabricated parquet, however, veneer parquet cannot be sanded, as the useful layer is less than 1 mm thick.
What does the parquet strength have an effect on?
Strength plays a role in the selection of the parquet in several respects:
On the one hand, the acquisition costs are usually higher for thicker parquet, on the other hand, the strength has a significant impact on the life span of the floor, which in turn makes the investment quite worthwhile.
Parquet with a higher thickness not only withstands the daily stress better, but can also be sanded more often, which is important for carrying out renovation work.
Wear and tear or damage to the parquet can be removed relatively easily by grinding. As a guideline, parquet floors should be renovated every 10 to 15 years and approx. 0.3 to 0.5 mm of the parquet surface are removed per grinding process.
The strength of the parquet is also relevant in terms of spatial conditions.
Parquet floors with less thickness are advantageous, for example, in rooms that require a lower height of the overall floor construction. But even in transitions, such as at door sills, the strength of the parquet can be decisive.
In addition, the parquet thickness – together with the type of wood used – also affects the heat transfer resistance of underfloor heating systems. The higher the thickness of the parquet, the more support the underfloor heating reacts and the slower the room heats up.
