How does it differ from the standard solid structural timber and glulam?
BauBuche has significantly higher strength and stiffness properties compared to solid structural timber and glulam. For example, the bending strength of BauBuche GL70 is almost three times greater than that of standard solid structural timber C24 or glulam GL24. As a result, significantly smaller cross-sections can be used, and more slender construction can be carried out.
What construction requirements need to be taken into account by carpenters?
The processing of BauBuche beams is practically identical to that of conventional softwoods. Carpenters mainly have to pay attention to moisture protection. If the BauBuche is subjected to weathering during the construction phase, this could lead to swelling and the formation of stains. We therefore recommend applying a hydrophobic treatment as protection for transport and assembly (e.g. Remmers, IL 170). Trimming can be easily performed using conventional joinery machines. All of the screws need to be predrilled. Fully ground drills should be used for drilling (such as the HSS-G wood drill from Famag).
What benefits are there for carpenters?
BauBuche provides carpenters with a high-performance material. BauBuche beams are extremely well-suited for components under high loads:
Broad dropped beams can be produced with more slender dimensions thanks to the high bending strength and the high modulus of elasticity. And in limited spatial conditions, as is the case in restoration, the lower cross-sectional height also opens up a number of important benefits.
The compression strength along the grain of up to 70 N/mm² allows for more slender columns.
The high compression strength perpendicular to the grain of up to 10 N/mm² makes BauBuche the perfect material for thresholds. The support areas can be reduced in main and secondary beams. Steel transverse pressure reinforcements can usually be omitted when using BauBuche.
The BauBuche is supplied with a wood moisture level of approx. 7%. The shrinkage of components under pressure, and the associated subsidence that often occurs with glulam (wood moisture level on delivery approx. 12%), does not occur with BauBuche.
What benefits can carpenters promise their clients?
Carpenters can offer their clients a more slender structure with an elegant hardwood look. Matching board materials and BauBuche Flooring are available for interiors or furniture. The components are also very resistant to mechanical damage thanks to their high densities. And all of that at similar prices to those for conventional softwood products.
