Hi everyone, I’m wondering if you have any experience or ideas on how to make house construction as environmentally friendly and sustainable as possible? Are there any companies that specialize in natural building materials?
Best regards

As an alternative to hemp insulation, there is also wood fiber insulation. It is completely natural and has all the properties mentioned here – mold resistant, solvent-free for allergy sufferers, sound insulating, and provides excellent protection against cold, while especially offering much better protection against summer overheating.
In combination with clay plaster or earth plaster, this creates a healthy wall assembly.
At the company Emoton, this combination was developed into an alternative installation layer and is patent protected. Clay plaster with a thickness of about 55 mm (2 inches) has two main advantages: thermal mass and the ability to absorb and release (air) moisture. This improves thermal comfort in summer and the dryness of indoor air in winter.
If my clients had some extra budget besides their creative finishing ideas, I would recommend this to everyone. 🙂

If my clients had some extra budget alongside their creative design requests, I would recommend it to them all. 🙂 Thermal mass is already sufficiently provided by the wood fiberboards combined with a 1 cm (0.4 inches) clay additive plaster layer on top. Clay plaster contains about 50% more clay due to its purity compared to standard clay plaster and can absorb up to 10 liters (2.6 gallons) of water per square meter without deforming. People don’t shower often or long enough for this moisture storage to be insufficient.
In the laboratory, I observed that after one hour of showering, the plaster was only about 2 mm (0.08 inches) damp.
The main advantage, however, lies in the application process:
For a client (a prefab home provider in the Blue Lagoon near Vienna) in Austria’s largest prefab home park, I calculated the cost difference for their standard interior finish, including an installation cavity, yellow mineral wool insulation, and drywall. The eco-friendly and fully natural system cost an additional €3600, calculated for their standard model home.
This includes the wood fiberboards and plaster!
So, it’s not as expensive as many might think.
