The wall assembly of the Munich mass timber home is based on untreated mountain timber, free from construction chemicals and chemical wood preservatives. The structure is fully diffusion-open, eliminating the need for vapor barriers or plastic membranes. The massive timber components naturally regulate moisture and indoor climate. In combination with dense wood fiber insulation, the assembly achieves high airtightness while remaining breathable.
Despite its metal-free construction without full-surface ad, the system complies with stringent German energy efficiency requirements. It provides warmth in winter and effective heat protection in summer thanks to the thermal mass of the timber. By using LIGNOLOC® wooden nails, a pure wood-to-wood connection is created – without corrosion risk or thermal bridges caused by metal fasteners, and optimal circularity at the end of the building’s life cycle.
