BauBuche Board S/Q
The laminated veneer lumber is available as boards bonded parallel to the grain (S-board) as well as with approximately 20 % cross-layers (Q-board). BauBuche S-board is mainly used to produce bar-shaped components. BauBuche Q-board is used for elements of surface structures such as load-bearing wall panels and for all applications where large-format boards are needed due to the high resistance to warping resulting from the crosslayers. The premiumquality beechwood surface is sanded and can be finished for a visually pleasing look.

a) Values apply for h ≤ 300 mm. For 300 < h ≤ 1.000 mm, the characteristic
strength must be multiplied by the coefficient
kh = (300/h)0,12
h = is the decisive dimension in mm for the bending load of the overall cross-section

Ingenious hardwood

Wood as a building material has recently been experiencing a well-deserved revival. Its versatility as a material has long been known but its significance as a renewable resource has only been re-discovered in recent years.

Until now almost exclusively softwoods were used in timber construction. To process hardwoods as building material used to be too complicated and too expensive.
At Pollmeier, we have changed that. With the aid of applied science we were able
to develop a completely new process technology, which allows us to economically produce top-quality laminated veneer lumber from Euro­pean beech for structural applications. We call it “BauBuche” and we use only raw materials from local and sustainably managed forests in its production.

The tree is rotary peeled in one of the most modern production facilities in Europe and transformed into a high-tech material with hardly any loss in value of the material. This is carried out in production line precision: on the one side a whole tree trunk is fed in, on the other side out comes BauBuche. BauBuche includes boards and beams for structural timber construction as well as panels for furniture and interior design.

With its exceptionally high strength BauBuche allows structures with significantly slimmer dimensions, compared to softwood materials. The high surface quality makes BauBuche ideally suited for visible construction elements. And the cost-efficient manufacturing technology places structures using BauBuche at the same price level as conventional softwood structures.

  • BauBuche uses local raw materials from sustainable forests with PEFC certification.
  • BauBuche is beneficial both to the environment and people because
    at its source in the forest it produces oxygen and binds CO2.
  • Applying precise engineering technology, BauBuche preserves the morphology and strength of the natural wood.
  • BauBuche carries higher loads than softwood products.
  • BauBuche has a wide range of applications – from the smallest component
    up to 18-meter-long boards and beams.
  • The load-bearing capacity of BauBuche reduces dimensions and cross-sections
    in timber construction – more space and less material consumption.
  • BauBuche is distinguished by its 3,7 mm veneer layer precision and exceptional surface quality.
  • BauBuche is as easy to work with as solid wood, and is ideally suited for use
    in visible construction elements..
  • BauBuche revitalized the possibilities of laminated veneer lumber with top-quality aesthetics and unmatched strength.
  • The high density and uniformity of BauBuche saves on fasteners and thus costs.
  • BauBuche is price competitive through efficient manufacturing and economical use of materials.
