Wood strip flooring

Solid wood elements with groove and/or tongue according to EN 13226 are solidwood strips of soft- or hardwood with a thickness ≥ 14 mm, which at one longitudinal side and at one width side are provided with a groove each and at the respectively opposite side with a planed tongue each. In Europe, solidwood elements are usually manufactured with thicknesses of 22 mm, but thicknesses of 15 mm, 16 mm, 19 mm, 20 mm und 23 mm are also common. The product is defined with a length more than 250 mm and a with above 40 mm. The edges of the elements may be bevelled; the bottom side may have one or several adhesive rebates. For elements without surface treatment, the top side must be smoothed. The type of wood is selected depending on the requirements of use in the structure and must be stated. The most common types of wood (hard- and softwoods) are listed in Appendix A of the standard EN 13226. Sorting is undertaken into the three appearance classes ⚪, △ and ◻. According to the national preface of EN 13226, in Austria the free sorting "exquisite" (for oak, ash and beech) is used for determination of the sortings. Depending on the manufacturer further free sortings (classes) are also possible, they have to correspond to the principles of Appendix B of the standard EN 13226. The fire behaviour of the parquet is classified according to the classification report of the manufacturer or according to EN 13501-1 (Cfl-s1, Dfl-s1, Efl – according to product details and end-use condition). The CE-certification of wood flooring and parquet has been compulsory according to EN 14342 since 01.03.2010.

 

Multi-layer parquet

Multi-layer parquet elements according to EN 13489 are elements consisting of a wear layer of solid wood with a thickness of at least 2,5 mm and one or several support layers of wood or wood composites, which are glued with one another. Predominantly 2-layer parquets (wear layer and support layer) and 3-layer parquets (3-layered setup) are manufactured. 2-layer parquets have thicknesses of 9 to 22 mm, 3-layer parquets mostly thicknesses of 10 to 22 mm. Rectangular and square element shapes are manufactured. According to the national preface of EN 13489, in Austria the rectangular elements do have widths between 100 and 240 mm and lengths between 1200 and 2400 mm. Larger formats are mostly offered as 3-layer setups. Square elements have widths or lengths of 240 to 800 mm. For the wear layer, the types of wood oak, common beech, ash, spruce and larch are predominantly used. The elements must be precisely machined and smoothed. In order to guarantee proper laying, grooves and/or tongues at all sides are necessary. Multi-layer parquet elements comprise prefabricated and panel parquet as well as parquet boards. They all are getting a surface treatment while finished at the factory. Sorting is undertaken into the three appearance classes ⚪, △ and ◻. Depending on the manufacturer further free sortings (classes) are also possible, they have to correspond to the principles of Appendix B of the standard EN 13489. The fire behaviour of the parquet is classified according to the classification report of the manufacturer or according to EN 13501-1 (Cfl-s1, Dfl-s1, Efl – according to product details and end-use condition). The CE-certification of wood flooring and parquet has been compulsory according to EN 14342 since 01.03.2010.

Mosaic parquet

Mosaic parquet according to EN 13488 consists of individual solid wood slats with a thickness of 8 mm, a width of up to 35 mm and lengths of 115 to 165 mm, which as a laying unit, for example, are held together by netting glued to the bottom side. The mosaic parquet slats of equal dimension are joined into a square and thus form a mosaic cube, which like a chessboard can be joined into mosaic parquet panels. Further laying units are also possible, for example bond, herringbone, etc. The type of wood is selected depending on the requirements of use in the structure and must be stated. The most common types of wood (hard- and softwoods) are listed in Appendix A of the standard EN 13488. Sorting is undertaken into the three appearance classes ⚪, △ and ◻. Depending on the manufacturer further free sortings (classes) are also possible, they have to correspond to the principles of Appendix C of the standard EN 13488. The fire behaviour of the parquet is classified according to the classification report of the manufacturer or according to EN 13501-1 (Cfl-s1, Dfl-s1, Efl – according to product details and end-use condition). The CE-certification of wood flooring and parquet has been compulsory according to EN 14342 since 01.03.2010.

Solid hardwood boards

According to EN 13629 these are solid boards or pre-assembled elements of hardwood with groove and/or tongue. Hardwood boards are single-layered elements with thicknesses more than 10 mm, widths above 90 mm and lengths above 400 mm. Pre-assembled single-layered hardwood board elements have thicknesses more than 10 mm, widths above 110 mm and lengths above 900 mm. These elements are combined from several strips (smallest individual element) using dovetailing, narrow side and face side gluing. Hardwood boards and pre-assembled solid hardwood board elements have parallel sides, a uniform thickness as well as constant profiles at the narrow and face sides, and can be joined with other similar elements. The type of wood is selected depending on the requirements of use in the structure and must be stated. The most common types of wood (hard- and softwoods) are listed in Appendix A of the standard EN 13629. Sorting is undertaken into the three appearance classes ⚪, △ and ◻. Depending on the manufacturer further free sortings (classes) are also possible, they have to correspond to the principles of Appendix B of the standard EN 13629. The fire behaviour of the parquet is classified according to the classification report of the manufacturer or according to EN 13501-1 (Cfl-s1, Dfl-s1, Efl – according to product details and end-use condition). The CE-certification of wood flooring and parquet has been compulsory according to EN 14342 since 01.03.2010.

Solid softwood boards

According to EN 13990 groove-and-tongue boards of solid softwood, which mostly have thicknesses from 18 to 34 mm and widths from 70 to 192 mm, are called floorboards. The length of the board must be at least 1,5 m. The ends of the boards can be cut even or provided with groove and tongue. The floorboard can be fingerjointed. The boards must be planed at four sides along their full length. At the rear may only be scraped 20% by the planer knife. The visible side must be smoothly planed and a visible plane mark distance of up to 2 mm is allowed. The type of wood is selected depending on the requirements of use in the structure and must be stated. Sorting is undertaken according to specified characteristics (sortings A and B according to Table 3 of EN 13990).  Depending on the manufacturer, free sortings (classes) are offered as well, in which all sorting characteristics according to Table 3 of EN 13990 must be listed. The fire behaviour of the parquet is classified according to the classification report of the manufacturer or according to EN 13501-1 (Cfl-s1, Dfl-s1, Efl – according to product details and end-use condition). The CE-certification of wood flooring and parquet has been compulsory according to EN 14342 since 01.03.2010.

Vertical finger parquet

Vertical finger parquet according to EN 14761 consists of solid wood slats of hard- and softwood, joined together in an upright position, which are held together as laying units and glued to the subfloor. The thicknesses of the parquet are usually offered from 10 to 25 mm. The length of the slats ranges from 115 to 320 mm. The process is usually parallel laying at first, after that the parquet is getting an surface treatment. The most common types of wood are listed in Appendix A according to the harmonized standard EN 14761. The type of wood is selected depending on the requirements of use in the structure and must be stated. According to EN 14761 there are also no sorting rules for vertical finger parquet considering color, knot cluster, grain, sapwood and discolouration. However, it is recommended to define a free class for the respective type of wood and sorting. This free class has to be agreed between the contractual partners and must correspond to the predefined sorting characteristics. Principles of the free class are stated in Appendix B of EN 14761. Beside the mostly common vertical fingers, the EN 14761 also defines wide slats and modular blocks. The fire behaviour of the parquet is classified according to the classification report of the manufacturer or according to EN 13501-1 (Cfl-s1, Dfl-s1, Efl – according to product details and end-use condition). The CE-certification of wood flooring and parquet has been compulsory according to EN 14342 since 01.03.2010.
