BauBuche Board S/Q: Finishes

BauBuche is produced from beech veneers on a continuous press. In the outer plies, the veneer joints are visible as scarfing joints. As beech veneer is a natural material, it might also feature knots, cracks and colour variations.

 

BauBuche boards are available in two finish grades:

 

Thickness ≤ 40 mm

Thickness 60 mm
Non-visible quality Standard, both sides Standard, both sides
Industrial-sight quality  Available on request, top side Unavailable

The specifications refer to entire standard boards in a thickness of 40mm and below. Where relative values are specified, the defect rate in individual board sections might vary. 60mm boards are exclusively available in “non-visible” quality on both sides
