It is not the purpose to discuss taste and fashion here. Nevertheless, I would like to offer some thoughts which might give you another point of view for your building project.
When landscape photographers want to convey beauty and harmony they often take photos of old buildings which have never seen a coat of paint.
A practical example in the trade laws, norms and standards which regulate the wood industry. They grade by the exact numbers and size of branches in a board or beam. Our experience however shows that the amount of branches is one of the least criteria which contribute to quality.
History tells us that gut feelings and experiences of ordinary people sometimes have been way ahead of their times. Often scientific proof came quite some time later."
Note: Professor Reinhard Furrer was a famous German physicist and astronaut who, while taking part in a space project, has circumnavigated the earth 120 times. He died in 1995.
In 2012, Dr. Thoma's company built an energy self-efficient 5-floor commercial wooden building in Hamburg. This is ArcheNEO in Oberndorf, Tirol. A 6,600 square meter office complex, in which tenants’ leases state that they will not have to pay even a penny for heating throughout the year. The whole complex is built out of wood and not a trace of chemicals were used. Its temperature is regulated by heat pumps powered by photovoltaic batteries located on the roof.
This is the Haramura church near Fukushima in Japan which withstood a well-known earthquake for its destruction. Moreover, it is capable of surviving typhoons of up to 200 km per hour. One should know that for concrete, it is irreversibly damaged once it passes breaking point. Wood, on the other hand, flexes, shifts into the elastic phase, and then returns to its original form.
For this purpose, a research project was created, which involved the best BMW specialists in engine thermodynamics. It turned out that wood has two completely unique thermodynamic properties. 1 kg of wood accumulates 2.5 times as much heat as 1 kilogram of stone, and the time required to change its temperature is much longer than any other natural, raw material.
In the summer, the facade warms up to an average temperature of twenty degrees Celsius from the outside and only a small, solar-powered air conditioner is at work. To obtain such a result, the building has been modeled after a red ant forest anthill. The larval hatching chamber at the center of the mound is exceptionally resistant to variations in outdoor temperatures.
This is the Austrian, state-of-the-art film archive, which houses 70,000 historical nitro-film reels. Fumes from the film erode rebars in reinforced concrete and therefore wood becomes most suitable for this purpose. This archive requires no external sources of electricity, and the constantly monitored temperature is at 3 degrees Celsius throughout the year as fluctuations are unacceptable in this case.
This seven-floor hotel is built completely out of Holz100 – 100% pure wood. It proves day by day the incredible static strength of this natural, raw material. More so, there is even a huge swimming pool located on the seventh floor which boasts a open-air panoramic view of surrounding mountains. Starting from the day that its foundation was laid, the time that it took to officially open its doors only took 2 months.
Acoustic insulation is very important in the construction of hotels. The NaturHotel Waldklause Hotel built by Dr. Thoma is the quietest hotel in the world - the sound insulation values of the wooden walls between rooms reached 63 dB! This means that you can play drums in one room while those in the next room won’t be able to hear a thing.
It has also been found that wood is best suited for the construction of rooms with the highest level of surveillance protection required as well. Thanks to this finding, Dr. Thoma's company has received a number of orders to build various structures for the German army.
Solid wood is not only the safest material when it comes to fire, flood or earthquakes, but it also protects its inhabitants from all kinds of harmful, high frequency electromagnetic waves. It completely stops, for example, mobile phone frequencies. This has been confirmed by research conducted by the Bundeswehr University in Munich.
Not only is our building system entirely prefabricated, its time required to assemble a single family house of approximately 150 sq.m. in living space can be built in a single day!
The entire Thoma Holz100 system is patented internationally. Composed in three categories, its wall systems, ceiling systems, and roof systems make a complete house that becomes an inhabitable bare shell.
Extensive research has been done to combine existing high-quality technical values of wood with physical properties made building-specific which not in the least minimizes the cost of building.
Can you believe that there are Holz100 homes built that are without added insulation? Our thermal walls make it possible for even external walls to have outstanding energy standards, even with minimal insulation and therefore wall thickness.
Our Holz100 Thermal Walls achieved a heat insulation value otherwise reserved solely for materials classified as insulation at their full static load carrying capacity. To be specific, its lambda value reaches 0.079!
Thermal insulation is substantially improved by reducing the wall's thermal conductivity. We also make use of wood fiber, a pure and natural insulating material made of wood which is comparable to fiberglass insulation.
Holz100 Thermal Walls use its integrated structural insulation created by the milled grooves in each layer of wood as it acts as macroscopic air cusions laminated into the wall without circulation.
Our "Thermal Walls" which are similar to its standard counterpart is equipped with a different feature - grooves milled into individual layers of wood with a thickness of 20mm to 80mm.
In the manufacturing plants, the aforementioned processing of one Holz100 component results in a solid wooden wall as large as 3 by meters and up to 40 centimeters in thickness which contains nothing but pure wood as no synthetic resin glues or nails are not used.
Wooden dowels that are completely fitted through the standing core along with its layered wooden boards absorb additional ambient humidity and swell up due to becoming moist in this process, connecting non-detachably to surrounding wood.
The hardwood dowels themselves are dust-dried, compressed mechanically, and finally hydraulically pressed in.
The external walls are fitted at the factory with one layer of house wrap which is securely placed between two layers of boards.
The wooden board layers of a standard wall stands in a thickness of 20mm to 60mm that are cross laminated inside and outside. It is then connected to a top and bottom belt of 40 or 80mm as a standing core with wooden dowels set as a raster.
