A Building that is Safe for the Biosphere and Creates a Healthy Climate

Thoma - Holz100

The pure wood construction system "Holz100“ consists of wood and nothing else – it is free from additives like timber preservatives or glue.

Since 1990 Thoma has realized around 2000 buildings with materials that have a positive impact on the inhabitant’s health and environment. The pure wood construction system „Holz100“ consists of wood and nothing else – it is free from additives like timber preservatives or glue. The building envelope has no moisture barrier or toxic outgassing and it stores CO2. The walls even hold the world record in natural thermal insulation. Latest scientific research findings suggest that people living in a pure wood environment show a reduced heart rate and a strengthening of the immune and nervous system. Holz100-houses are prefabricated in factories that are run by solar energy and produce no waste.
