Solid wood or double layer floorboards?

Double-layer floorboards consist of a solid oak top layer glued to a birch plywood base. Such boards grow less and swell under the influence of air humidity, therefore they are more stable in size even with large widths. For warm floors, it is recommended to choose glued boards. Solid wood is well suited for narrower boards and parquet.

What is the difference between two-layer and three-layer boards?

Two-layer or, more correctly, multilayer (in English "multilayer") boards consist of a top loadable layer of wood, which is glued onto a plywood-bearing structure. Plywood consists of many shavings of peeled veneer glued together crosswise. Thus, if three-layer materials consist of three layers, then a two-layer floorboard, for example, in the case of a 16mm thick Stalgen floorboard, consists of 10 layers. Stalgen products use veneers of ultra-thin lob shavings. Thus, a very stable construction is obtained. Stalgen two-layer boards, the topcoat is glued to the plywood with polyurethane thermosetting "hotmelt" glue, which is melted at 140°C. After gluing, the adhesive layer is practically unbreakable. Polyurethane glue does not have harmful fumes. For Stalgen products, only the highest quality waterproof ULEF (ultra low emission formaldehyde) birch plywood is used. Since birch plywood has a density of around 700kg/m³, while oak has an average density of 750kg/m³, the product conducts heat well. Thermal conductivity is inversely proportional to the density of the material. The lower the density of the material, the worse it conducts heat. For three-layer materials, pine, spruce, or in the worst case, aspen wood are usually applied to the load-bearing structure. Therefore, three-layer materials have a relatively additional significant drawback, they are not only geometrically more unstable, but also conduct heat worse.

What are the differences between the grades of floorboards?

The quality of the boards is the same for all grades, only the visual appearance differs - the quantity and size of the branches, variations in color shades, with or without a collar.  Premium and Select materials are obtained in small volumes, their availability is limited. Examples of sorting are given here.

Premium floors boards with individual dotted branches without a slough 

Select  Floor boards with small branches without sloppy wood

Living  Floor boards with small branches and sapwood

Classicfloorboards with branches, their repairs, without sapwood

Rustic  Floor Boards with branches, their corrections, color variations and sapwood

How wide boards to choose?

The width of the boards is usually chosen depending on the size of the premises. The larger the rooms, the wider the boards are suitable for the rooms. However, it should be noted that wider boards are more expensive.

How much do floorboards and parquet cost?

Prices vary widely - from EUR 20 to EUR 150 per square meter. Generally speaking, the wider and longer the boards, the more expensive. The grade also determines the price. Branchless material is much more expensive. The prices of floorboards and parquet change depending on the situation in the timber market.

Are floorboards suitable for warm floors?

For warm floors, glued floorboards of any width are suitable. For the manufacture of Stalgen products, waterproof birch plywood is used, for which oak is glued to the plywood with polyurethane glue. The density of plywood and oak wood is above 700 kg / m³, thus a good heat transfer is ensured (the higher the density of the material, the better its thermal conductivity). To ensure an ideal heat transition and prevent the formation of gaps between the boards in the winter season, it is desirable to glue the boards to the base.

What finishing material to choose?

How to calculate the amount of floorboards or parquet required for laying the floor?

We recommend that you check the actual area of the premises by measuring them in nature. Pay attention to! Floor area calculations also include niches, threshold area, as well as the area under built-in cabinets, kitchen appliances, radiators and elsewhere.

What is the required reserve of floorboards or parquet?

In small rooms, a reserve of 4% for floorboards, 10% for herringbone parquet. In large rooms, the amount of reserve is smaller. In trapezoidal rooms or when laying floorboards or parquet diagonally, the amount of reserve increases.

How to calculate the amount of floor slats required for laying the floor?

We recommend checking the required size of the floor slats by measuring them in nature. Floor slats are often installed in tiled floor areas as well. As a reserve, we recommend taking 3 meters for a private house.

Is it possible to order skirting boards in the same tone as the floor covering?

Is it possible to order boards of specific sizes?


What is the packaging of the floorboards?

The boards are sorted and packed in three length groups - from 0.6m to 1.4m, from 1.4m to 2.2m and from 2.2m to 3.0m. Boards come in variable lengths, 6 boards per solid wood board pack, 4 boards per double ply board pack. The total length of the boards is indicated on each package.

How much does oak parquet and floorboards weigh?

The weight of one square meter of two-layer oak floorboards with a thickness of 12 mm is 7.8 kg/m². Boards with a thickness of 16 mm weigh 11.5 kg/m².

What affects the price of parquet?

The price of parquet depends on the type of parquet (solid wood, two-layer, three-layer, etc.), the thickness of the parquet, the thickness of the top layer of noble wood (the main price-influencing factor for multi-layer parquet), grading (wood without branches is more expensive), finishing (type and composition of finishing materials, compliance with environmental requirements ), width (more expensive raw materials are used to make wide blanks) and other factors.
