New innovations, ideas, suggestions?

As an alternative to hemp as an insulating material, there is also wood fiber insulation. It is completely biological and has all the properties mentioned here - mold resistant, solvent-free for allergy sufferers, soundproof, and optimally protects against cold while especially providing much better protection against summer overheating. In combination with clay plaster or earthen plaster, this creates a healthy wall structure.

At the company Emoton, this combination was developed as an alternative to the installation level and is patent protected.

Clay plaster with a build-up thickness of about 55 mm has 2 main advantages: thermal mass and the absorption/release of (air) moisture. This improves thermal protection in summer and the dry air in winter.

If my clients not only had creative expansion wishes but also some money, I would recommend this to everyone. :)

Clay plaster with a buildup thickness of about 55 mm has 2 essential advantages: storage mass and absorption/release of (air) moisture. This improves thermal insulation in summer and the dry air in winter.

If my clients had some money in addition to creative finishing wishes, I would recommend this to everyone. :)

Storage mass is already sufficiently provided with the wood fiberboards and a 1 cm clay insert plaster layer on top. Clay plaster has about 50% more clay content than conventional loam plaster due to its purity and can absorb 10 liters of water per m² without deforming. People do not shower so often and so much that this would be insufficient as a moisture reservoir.
In the lab, I was able to see how, after 1 hour of showering, the plaster was only moistened about 2 mm deep.
The great advantage, however, lies in the processing:
For a client (a prefab house provider in the Blue Lagoon near Vienna) in the largest prefab house park in Austria, I made a calculation for his standard expansion with installation level, yellow wool, and drywall. €3600 extra cost for a purely eco-friendly and biological system - calculated for his standard model house.
This includes the wood fiberboards and the plaster!
So it is not as much more expensive as many think.
