Scientists from neutral research institutes have found that there are no longer any effects of low-frequency pulsed high-frequency signals on biological processes and on the nervous system in their studies.
As part of an investigation of the Thoma Research Center in Goldegg more than 100 different building materials and their combinations were tested at the University of the Federal Armed Forces in Munich for their attenuation for technically generated, high-frequency waves. During the measurement it was examined how much of the emitted power penetrates the test specimen.
The result provided the best values for thick wooden walls!
Contrary to all expectations, the building material wood - tested in the form of non-glued, fully solid Thoma Holz100 walls - shields considerably better than, for example, brick variants or lightweight construction systems.
Here are the damping values of a 17.6 cm thick Thoma Holz100 wall:
At 900 MHz (D-Net), only 25% penetrate through the wooden wall
At 1800 MHz (E-net), 10% penetrate through the wooden wall
At 4 GHz, only 1% penetrate through the wooden wall
Starting at 6.5 GHz, less than 1 per thousand already penetrate through the wooden wall

Building with the forest:
Everything remains valuable
In the production of Holz100 homes, everything remains valuable. This concept of waste-free recycling economy provides us with a sustainable, growing forest. Holz100 opens up new dimensions of sustainable construction with the first true circulation concept in the construction industry.
Since 1990, Thoma has been developing building materials that not only have a positive impact on the health of the residents, but also on the environment. The Thoma company relies on natural wood.
Holz100 is an award-winning solid wood building system and was the first building material in the world to be awarded the gold "Cradle to Cradle" certificate. It consists of nothing but untreated wood that has been harvested to the proper lunar phase and is completely free of toxic additives such as glue, chemicals, or wood preservatives.
Wood treated with glue or wood preservatives is not only harmful to the health of the residents of the house due to its outgassing, it must also be disposed of as hazardous waste in case of demolition. However, this is not so for Holz100 homes. It is completely natural and can be reused after generations of use both thermally and materially.
To recycle a Holz100 house you only have to dissolve the mechanical connections that hold the house together. With the raw materials released, a new house can be built.
Holz100 homes are prefabricated in factories that run on solar power in which no waste is produced. In the production of our Holz100 walls, all processing is optimized so that almost no waste is produced here as well. The small amount of waste that may be produced can be thermally recovered and immediately supply the production plants with energy.
As it is in the forest, everything stays in circulation and we can create a future suitable for grandchildren.
Raw materials in the cycle
Even when laying the individual components, care is taken to ensure that as little as possible of the precious raw material wood is lost. Window and door openings are recessed.
A farmer from the surrounding area of our Holz100 plant in Stadl picks wood chips from the production of our houses. "The chips are perfect for mucking out my stables - they are dry and pure in nature!"
It does not look like this with us! The waste from the wood glue binder production would have to be disposed of as hazardous waste as shown above. Our factories however, are devoid of and encounter no such problem.
Energy generation then and now
The steam engine that drove the saw Gußwerk 1907 is still standing. It is no longer in operation.
Today, a highly efficient biomass cogeneration plant supplies the saw and the village of Gußwerk with green electricity. Small remainders from the Holz100 production are also used to generate energy.
'I am working in the building and real estate industry and a few years ago, I built a house for my wife and me. This house had external wood cladding which was painted with some wood preservatives as was usual then. Two years later, my wife gave birth to our first child which is now physically and mentally disabled. We never tried to prove a connection between the wood treatment and the disability of our child; it couldn't make our child healthy either. However I do know now that treating the external cladding of our house was the biggest mistake I ever made.'"
Why Toxic Wood is a Concern
Synthetic paints, chemical treatments and large-scale wood lamination turn wood into a mix of different materials and compounds. Their effect upon humans is mostly unknown and it is impossible for the average consumer to correctly gauge the risk they are taking with these products.
Here is an excerpt from the 'Salzburger Nachrichten' back in the year 1993:
"Wood preservatives, two parole sentences"
Frankfurt Main (SN, APA). On Tuesday the Frankfurt "Wood Preservative Trial" sentenced both accused men to one year suspended prison term each and a total fine of 1.7 million Schillings, payable to several joint plaintiffs.The executive directors of the company XYZ, 64 year old XY and 62 XY were both sentenced guilty of negligent bodily harm, concomitance, the negligent release of toxins and selling toxic goods while being well aware of the danger they are posing."
Please, allow me now to tell you about my own personal motivation and why our family started taking toxic chemicals seriously.
Nobody was suspecting that building materials were going to cause serious harm to anyone's health. Our family was perfectly healthy until suddenly two of our children started coughing and having breathing difficulties.
First without fever, later with a slight temperature rise, followed by asthma attacks, fear of going to sleep and cries for help at night: "Mama, Papa, why can't I breathe anymore?" The first doctor didn't have a diagnosis but prescribed a dose of penicillin. The next doctor didn't have any idea either as to why this condition was persisting. He prescribed cortisone for our children and elaborated in their presence, how they would have to carry a puffer with them for the rest of their lives.
We needed a third doctor before we realized we couldn't expect any help from conventional medicine in this matter. This third doctor tested for allergies. Holding our boy's arm he exclaimed: "Oh my God, this boy is allergic to just about everything!"
Our commonsense told us that those medical reckonings couldn't be correct. Our children grew up in the Alps with goats, chickens, dogs and cats. There were no allergies or any other symptoms. Our son in particular spent a fair amount of time in the company of our Billy goat.
Apart from the goatish scent, we never noticed anything having a negative impact on him. The health symptoms had appeared just after we moved into our new house. We thought maybe something in our new environment was having this effect on our children's quality of life.
When looking closer at our new surroundings, we soon realized the house was playing a big part. The brick work was not insulated and therefore there were no dust or microfibers from mineral wool or emissions from plastic insulation. The wood cladding was not treated either and we ruled that out as a possible cause as well.
However, the floors were a different story all together. All the rooms had particle-board floors covered with carpets and vinyl. Particle boards are nothing more than wood shavings mixed with synthetic glues and pressed into boards.
Shortly thereafter, our children were back to their normal healthy selves. What a relief! Like the man who made the biggest mistake. We too couldn't find a 'scientific diagnosis' for the disease of our children. The most important thing for us was the result: Our children have their health back.
I remember the times when he was ill in bed and I told him that every illness has a reason and how faith can move mountains. We all believed strongly that one day he would be running again like a deer in the forest.
The question: "Mama, why can't I breathe anymore?" cannot stay unanswered.
Just think about how it could have ended if we had taken the advice of any of the doctors, if we were prepared to settle for an asthma puffer and not changed the floors of our home at all! Just now, while I am writing these lines, our eldest son has come home from school and told us that he was the fastest runner today.
Following the motto "Nomen est Omen", Matthias Würfel developed a "living cube" with a holistic approach. The construction method should be healthy, ecological, valuable, compact and flexible. The architect referred to the geometric rules of the cube to combine energetic advantages with a playful freedom of design. The client can individually adapt the individual modules in different design grids to his needs.
"The building enables living in the material cycle of nature and is sustainable on all levels. This means not only the use of CO2-neutral natural materials, energy-efficient construction and heating with renewable energy sources, but also the saving of long transport routes in the manufacture and construction of the building, "says the architect.
Holz100 is 100% free of toxic building chemicals. But it gets even better - with Holz100, you're surround by solid wood; just like second skin. Free of harmful off-gassing, and instead it provides its inhabitants of invigoration and healing. The Holz100 house is the best foundation for deep, healthy sleep and an active, dynamic life full of strength and tranquility.
For many, the dream of owning a house in the countryside is linked to the desire for health and exposure to nature. The choice of the main building material, one which does not burden the health, is particularly important.
The development of new building materials has progressed rapidly since the 1970s, and today everything seems technically feasible. But there is also a steadily rising number of health complaints, the causes of which could be traceable to the immediate living environment. Residual poisons found in some building materials and furniture can release polluting substances for years. They are considered as possible causes of allergies and other diseases as well. The health effects of evaporating plastics, foils of all kinds, solvents, adhesives and other construction chemicals are always posing new challenges.
The key point for a sustainable preventative measure of such avoidable diseases lies in the conscious decision for building with biologically harmless materials. For this reason, builders increasingly demand from planners, property developers or suppliers a full declaration of the processed material from resource, harvesting, and manufacturing. For Holz100, this list of declarations is short: wood. Holz100 is made entirely and exclusively of high quality wood.
With Holz100, not only does it surround its inhabitants with a completely unadulterated building material, Holz100 also strengthens your immune system, calms your vital nervous systems and helps you to live longer. Wooden rooms are so reassuring to our body systems that every night (proven scientifically), we save ourselves an hour of heartbeats each day.
These and other new research results on the health-promoting effects of wood are presented in many, various ways - such as Planet Ark's "Make it Wood" campaign.
The water in a living being like a tree is more than just content in a tank which can be filled or emptied. The example with the oboes shows that at the end, kiln dried wood contains the same amount of moisture as wood which has been dried for 30 years. However, oboes made from kiln dried wood crack whereas seasoned wood doesn't, it stays stable and resonates.
The ability of wood to absorb and release moisture can be compared to a sponge. Timber which has been stored for a long time matures and dries slowly. It stays in shape even when the humidity is fluctuating, whereas younger and kiln dried wood tends to warp and bend. This principle always applies.
However, wood used for building and furniture manufacture has shorter drying and storage times than the highest quality wood used to build instruments. Depending on the type of tree and intended use, one to three years of air drying are sufficient here.
The rule to remember is: The faster the wood is drying, the more it will warp and twist. This is called the sponge effect. It means that on humid summer days, this type of wood absorbs more moisture from the surrounding air, expands and works harder than wood which has dried naturally over some years.
A stack of sawn boards which has been stored outside for a few years (protected from water), has been exposed to hot summer days as well as freezing winter nights. These boards have not only dried, they also experienced and adapted to the different weather conditions. This 'memory' has a relaxing effect on the wood.
In those years of storage and slow drying, something else and as important is happening: oxidation and several other processes cause the breakdown of nutrients for insects and fungi. This natural process to preserve wood is not happening when speeding up the drying process with a kiln (which takes from a few days to weeks).
Some economic experts who visited our saw mill showed utter disbelief when they saw a stack of oak boards which had been drying for four years. These boards were to be used for a solid wood floor at some stage. Four years of tying down capital when everyone knows you might as well kiln dry it in just a few days or weeks. How can you afford to leave this kind of capital lying around for such a long period?
From a business point of view this might seem right. However it doesn't have anything to do with using wood in the most ideal way.
The purely technical way of drying wood fast, unfortunately misses out on all the subtle benefits of working with nature. The resulting wood often needs to be treated with questionable preservatives or glues. Treated wood ends up as toxic waste and cannot be returned into the natural cycle to turn into valuable mulch and nutrients for other plants. It also cannot easily be burned either. This toxic waste is the beginning of a dead end road.
Communication by semiochemical substances represents only one type among many for trees. In his life’s journey, Dr. Erwin Thoma met another outstanding forester, Mr. Peter Wohlleben, whose books are also available in English. He made a surprising discovery about forests. As it turns out, communication methods between trees are incredibly complex. For example, trees recognize the saliva of various animals. Recent research by Leipzig University shows that when a deer bites a twig, the tree responds differently than when a person breaks it. Trees react to the saliva of caterpillars in yet another way. For example, oaks give off a special smell signal then, in the form of a semiochemical substance, thus calling predators such as hymenoptera bees for help. These lay eggs in the leaf-devouring caterpillars and as a result, the caterpillars get devoured from the inside by the newly hatched eggs.
Trees also communicate through their root systems called the wood wide web. It serves to convey warnings to its neighboring trees so that they could get ready for danger, such as insect attacks or drought. These signals are transmitted, as those in our nervous system, through electrical impulses and chemical substances. Where the roots of the trees do not reach, the information is transmitted through the connected mycelium network. Trees pay their "helpers" back by providing them with sugar. Mycelia are the largest living organisms on the Earth. Their size reaches thousands of acres, and some scientists claim that all mycelia on the Earth are connected. When trees at the bottom of the slope begin to feel the lack of water due to the drought, they inform other trees. These close their pores, thereby reducing water loss and slowing down photosynthesis. When one tree is attacked by wood borers, all trees within 50 meters change production to defensive substances. In our common larch, one of these substances is resin. It contains about 1000 complex chemicals and is the world's best natural fungicide, bactericidal and virucidal agent. Some trees can live more than 1000 years thanks to it. The ointment made from resin beats any pharmaceuticals that accelerate wound healing; however, it will never hit the market or doctors' offices, because its synthesis and patenting will probably never be possible, and pharmaceutical companies will not be able to make any money on it. This was stated by Professor Max Moser, who was mentioned earlier, and who was asked by Dr. Thoma to analyze the miracle wound ointment prepared by his grandmother. As a side fact, the same applies to Indian cannabis, which contains almost 445 unexplored compounds and is a cure for dozens of diseases, including cancer, as shown by the latest research in Germany and Israel, among others.
Hotel Seiser Alm of the Urthaler family is the largest wooden hotel in Europe with 45 family suites. Timber necessary for its construction was produced by the Austrian forest in an hour and a half. The forest not only has a healing effect on people, but it is also a system of exemplary economy. Forestry and economics are two academic areas of science which teach things that are completely the opposite. While we profit by exponential growth and elimination of competition is the only goal for the economy, the forest is based on cooperation to create the best conditions for the next generation. These are terms foreign to economists. Trees compete with each other only at the beginning of their careers, but they do not try to grow indefinitely and seize all resources for themselves.
When a tree dies, it returns each of its particles to where it came from. It leaves no waste in the wake of its life. Waste doesn’t exist nor is created. The only thing that exists is the circuit and cycle of its life. According to Dr. Thoma, this model is the only one we humans may model a sustainable economy on. There is no alternative. Dr. Thoma's computerized and robotized factory draws all the energy from photovoltaics and the surplus is returned to the grid. It manufactures without waste, from material that is created from carbon dioxide. Dr. Thoma claims that any economy or energy crisis is nonsense. The only crisis in the world is the crisis of our minds. We lack nothing other than the right concept for our economy. Today's furniture is made of particleboards glued together with chlorine derivatives and formaldehyde resins. They are extremely harmful to health and nature, and are classified as hazardous waste for the purpose of their disposal. Their disposal is more expensive than the purchase of solid wood of the same weight. However, it is a billion dollar industry supported by lobbyists and politicians. Humankind debates global warming caused by carbon dioxide, when one tree may neutralize tons of carbon out of the atmosphere. Instead of building waste-free wooden houses, we insulate them with styrofoam, which besides mildew offers minimal effects, and when soiled with plaster is almost impossible to dispose of. We burn carbon, gas, and oil to heat and cool buildings, when a few photovoltaic batteries can deliver more power to a wooden building than it needs. It is now the ideal time to start thinking differently. As you can see from Dr. Thoma's example, sometimes one man's perseverance is sufficient to initiate small, big changes in the world.
