Endless communication is made possible in today’s world with smart devices, cell phones, and even appliances that are all Wi-Fi enabled.  The cultivation of advancement in technology means that we are constantly bombarded with exposure to radiofrequency radiation. This radiation can cause a wide variety of symptoms & health concerns; even cancer. A person spends around 90% of their lives indoors; we need to reconsider the framework of the building envelop as the primary source of protection to minimize the effects of RF radiation.

​To ignore the dangerous effects of radiation and its link to technology is to be ignorant of the reality of its effect on our biology.  Thoma Holz100 is a building system that was developed using innovation in engineering technology and ancient wood doweling.  Harnessing the knowledge of moonwood and its benefits on the properties of wood – Holz100 provides inhabitants with a building shell that is made of pure solid wood; without glues, chemicals, or toxins.  The moonwood used in Holz100 has been tested to block high frequency mobile phone radiation better than reinforced concrete, bricks or other commonly used prefabricated systems.
​

Contrary to expectations, the building material wood - tested in the form of non-glued, fully solid Thoma Holz100 walls - shields much 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 the wooden wall
Starting at 6.5 GHz, less than 1 per thousand penetrate through the wooden wall

We are always exposed to some kind of high-frequency radiation: TV and radio broadcasting antennas, radars, cell phone masts, wi-fi wireless networks, cordless phones etc. But are you aware of its consequences? High frequency radiation has been linked to insomnia, depression, brain cancer, testis, skin, salivary gland, male infertility, miscarriages pregnancy, leukemia, etc. 

In May 2011, the World Health Organization (WHO) announced that wireless radiation is possibly carcinogenic. And as a building system that prioritizes the health and well-being of its inhabitants, we wanted to make sure that high-frequency radiation was not an issue. While building one of our first Holz100 homes, we noticed that the mobile phone reception was very weak inside the newly erected building and decided to investigate this phenomenon further.

The Munich University of the Federal Armed Forces became our scientific research partner and conducted more than 700 laboratory tests. Practically all of the well-known building systems on the market were tested for their protective qualities regarding electromagnetic radiation. The results were surprising even to their radiation experts and technicians.

Natural wood that we use in Holz100 achieved the best results. Holz100 panels blocked high frequency mobile phone radiation better than reinforced concrete, bricks or other commonly used prefabricated building systems.

The complete scientific publication about this issue can be viewed through the Erwin Thoma Scientific Research Center.

From: "Reduction of High Frequency Radiation penetration in Buildings", May 2000, updated in 02/02, by Prof. Peter Pauli und Dr. Dietrich Moldan.

Cell phones of the first generation often didn't work in Holz100 buildings. Meanwhile, the small percentage of rest radiation which enters through the window frames is enough for it to work. Residents of a Holz100 home still have the advantage of having its radiation density drastically lower inside the building compared to outdoors. Laboratory tests showed that Holz100 elements blocked up to 99% radiation, depending on frequency.

Say goodbye to high-frequency radiation!
