One choice for a healthier home
Ecological building starts with a craftsman who understands the technical nuances, not just the ideal.
The best insulation isn't made of glass wool
Bio-based insulation performs differently than conventional materials. We don't just look at lambda values; we consider the entire indoor climate.
Hemp
Moisture-regulating, vapour-open, and pest-resistant. Hemp insulation acts as a natural buffer.
Wood fibre
High thermal mass ensures temperature stability—keeping interiors cool in summer and warm in winter.
Clay
Beyond aesthetics, clay acts as a moisture reservoir, regulating humidity naturally without the need for mechanical systems.
Flax
Lightweight, easy to handle, and low-impact. Ideal for timber frame construction.
Protecting the building envelope
Correct detailing from the outside in is crucial for a healthy, durable home. We explain how vapour-open systems function and where the airtight layer belongs.
External wind-tightness
A vapour-open, wind-tight layer prevents cold draughts and protects the integrity of the insulation.
Waterproof yet vapour-open
Membranes that repel rain while allowing water vapour to escape prevent rot and mould growth.
Internal airtightness
A meticulously installed airtight layer eliminates heat loss and uncontrolled air currents.
Vapour control and transport
Managing the movement of moisture from the inside out ensures it never remains trapped within the structure.
Radiant heating in vapour-open structures
Wall, floor, and ceiling heating require a specific approach in ecological building. Daodejing advises on the correct combination of materials and systems.
Low temperature
Ecological heating operates efficiently with flow temperatures below 35°C, making it ideal for underfloor systems.
Hemp-lime as a thermal buffer
Hemp-lime floors store heat and release it gradually, significantly enhancing comfort levels.
Wall heating in clay
Natural clay plasters are excellent thermal conductors when used in conjunction with wall heating pipes.
Ceiling heating
Radiates heat from above; a space-saving option for high ceilings or timber frame builds.
The advantages of vapour-open walls for your indoor climate
Clay plaster allows your walls to breathe. By naturally regulating moisture, it prevents mould growth and maintains a healthy, balanced indoor climate.
Moisture buffering
Clay plaster absorbs excess moisture and releases it slowly to maintain a balanced environment.
Chemical-free
No solvents or synthetic binders—only pure clay and sand.
Thermal accumulation
The mass of the clay layer acts as a natural heat source within the home.
Breathable surfaces
Vapour-open walls prevent thermal bridging and condensation within the building fabric.
