Rubner Sawn Timber, Rubner Sawn Timber kiln dried, Rubner Sawn Timber machine graded

RUBNER sawn timber is produced from fresh roundwood, whereby the wood species spruce and pine are processed in accordance with EN 1912 (Picea abies and Pinus sylvestris). The roundwood for the production of RUBNER sawnwood originates from a predominantly regional supply network, the average delivery distance of the roundwood is around 80 km. Depending on the processing level, RUBNER sawn timber is available as fresh, dried, dried/pre-planed or dried/planed/(visually) machine-graded lath, board or plank sawn timber.

RUBNER sawn timber is manufactured from sustainable wood (PEFC) sourcing from sustainable forestry. After delivery to the production facility, a quality and volume assessment is carried out. After debarking, the logs are classified according to their diameter and temporarily stored at the log yard (dry & wet storage). In the sawing line, the logs are split into main and side boards with circular saws and then (side boards) prismatically edged. RUBNER sawn timber that is not dried is then visually graded and packaged. Dried RUBNER sawn timber is kiln dried after the sawing process, with a target moisture content between 10 and 18 percent. RUBNER sawn timber graded according to strength is pre-planed after technical drying and then visually or mechanically graded by strength. Optionally, the kiln-dried Rubner sawn timber is protected from the weather during intermediate storage and transport with foils. Technical data: RUBNER sawn timber has the mechanical properties required for use in timber structures according to EN 1995 (all parts). The following technical data apply to the properties of RUBNER sawn timber. The performance data of the product are in accordance with its essential characteristics according to EN 14081. Declared unit: This EPD refers to a declared unit of 1 m³ of sawn timber produced by the RUBNER group. The declared unit refers to an average density of 459 kg/m³ and wood moisture at delivery of 12 %.

RUBNER sawn timber classified according to purely visual criteria is used in the construction sector for both decorative and structural purposes. RUBNER sawn timber graded according to its strength can be used for the construction of load-bearing components in buildings and bridges. RUBNER sawn timber graded according to its strength is mainly used as a base material for various wood-based materials such as glulam, cross-laminated timber or finger-jointed solid structural timber.
