The forest is one of the ecosystem's most valuable renewable resources. The sustainable use of wood helps protect forests and all the benefits they offer for water, the soil, the air and for recreation. Wood can be produced in an environmentally-friendly way, is CO2 neutral and does not require a lot of energy to process. Germany is rich in forests, which represent a substantial potential economic resource. Timber as a building material also aids regional development.
Examples of existing buildings show that wood can be a modern building material that
· is light,
· has good thermal insulation properties,
· is easy to process and
· can be used as a material or used for heat.
Wood, the living building material
Wood is a biological building material that grows and decays as part of the cycle of nature. Wood is alive. People feel comfortable when surrounded by this living material. Whether in architectural construction, garden design or interior furnishings - wood makes us feel close to nature. Homes made with wood feel warm and cosy. That is surely an important factor in explaining how wood has held its ground against modern competitors like concrete, steel and plastic.
Wood is unique and distinctive. Nowadays it is more in demand than ever, thanks to people's growing desire for a sense of nature.
1. Production workflow (wood drying)
Our in-house drying facility at our factory in Fürstenau was no longer able to keep up with growing demand for DIN compliant timber. In order to avoid supply bottlenecks, and also so that we could remain independent of suppliers, drying capacity was doubled in July. The computer-controlled wood drying process is run on a scientific basis; sensors monitor the drying process and sophisticated control software guarantees optimal results.
This type of drying ensures the dimensions of the wood are accurate and stable, which is very important as it keeps dimension and shape alterations to a minimum in the final building. It easily fulfils the requirements of DIN 4074, which means future safety and the quality you expect can be guaranteed.
2. Production workflow (woodcutting)
The dried timber is professionally cut to the dimensions specified by the engineer using fully-automated, high-precision equipment. Thanks to modern technology it is not necessary to adjust the dimensions, because today's graphics and structural analysis programs use an interface between the calculated data and the machine. That means the data are transmitted directly to the machine and the desired measurements can be cut with absolute accuracy.
In order to keep production times as low as possible, work goes on with another saw at the same time. This is where the truss struts for the nail plate trusses are cut to measure.
This saw allows the truss struts to be cut in just one work process. Four large saw blades, each set to a different angle, accurately cut each truss strut.
This process also uses the most up-to-date computer technology
3. Production workflow (pressing the nail plates into the cut timber)
The computer-controlled special press places the nail plates on the cut timber at their designated connection points. Once the nail plates are precisely and correctly positioned at their different connection points, they are all pressed into the wood beams in one movement using the high-pressure special press. The connection points only need to be saved once, and next time they can easily be retrieved.
In order for the cut timber to become a finished product, the wood must be assembled into the shapes designed by the engineer. A template is constructed and used to ensure that all the elements are identical. Nail plates are used to connect the truss struts with the top and bottom chords.
These nail plates are galvanised steel plates fitted with a varying number of nails in a range of patterns. They can optionally be made from stainless steel (preferable for truss constructions with no suspended ceiling and for stables). They are manufactured or punched-out as one component. They are structurally designed to guarantee optimal stability and load-bearing capacity in each individual timber construction. Each connection point is exposed to different loads, so different size nail plates are used depending on the connection point.
