Holz100 walls are permeable and windproof. This combination results from the material structure of walls made of 100% pure, solid wood. Thoma also provides a 50-year guarantee against mold and condensation for his buildings. This is unique in the construction industry!
In the winter, the best values of the Holz100 system become particularly effective as it trumps all other building materials regarding the cooling time of the building envelope. That makes energy efficient living and self-sufficient passive houses without insulation and complicated building technology possible.
Holz100, thanks to its patented construction, absorbs heat almost twice as well as full or glued wood and thus holds the world record in thermal insulation among all building materials.
This wood is essential as there is minimum food for pests, is denser and therefore more naturally durable than conventionally harvested wood. No wood that contains toxins or preservatives can be safely dispensed.
Moonwood - Lasting for Generations
Wood harvested from the right time makes this possible. Holz100 only uses renewable, PEFC and FSC certified, native moonwood.
This is how wood is created in its best form:
Approval had to be sought for various individual cases before the project could be implemented. Ultimately, the project made recourse to building regulations that have been in force for several years in Switzerland.
The use of solid wood construction is also a novelty in Hamburg: this type of development is not provided for in the city’s building regulations or those in force in other states (cf. the White Paper “Urbaner Holzbau” ‒ Urban timber construction).
The “WOODCUBE” enters new territory by incorporating an exterior wall structure that contains dowelled cross-laminated timber elements as airtight building components, without the need for additional measures such as airtight pathways or engineered wood board.
