Backache? A hit of clay and everything passes. Let's not talk about clay but of a coating to be applied to domestic walls. The body can accept humidity values between 30% and 70%: the ideal is 50% and theclay is right for us.
As you move away from a percentage of humidity optimal, microclimatic situations are created that are favorable to the action of micro organisms harmful to human health. Both in too dry and too humid environments, viruses and bacteria strengthen their action. This is why it is important to maintain a dehumidified environment.
In a house with biocompatible coatings, the humidity inside the rooms is affected by the finishes and coatings such as plaster and floors. It is the walls that absorb thehumidity in excess and release it when the air becomes too dry. It has been shown that the first 15-20 mm of the wall (i.e. the internal plaster layer) are fundamental in determining the quality of the microclimate inside the inhabited space, thus also determining the percentage of humidity.
Clay is excellent humidity regulator for environment as it quickly absorbs or restores moisture according to need. A clay plaster is able to absorb and neutralize odors, smoke and numerous harmful substances.
There are radiant wall heating systems on the market with clay plaster. I'm prefabricated clay panels which contain copper or synthetic coils inside which hot water is circulated.
These panels, after being applied to the walls, are connected to the heating system as if they were common radiators. Advantages: considerableenergy saving, dust reduction, high thermal comfort, in addition to the advantages offered by a clay plaster.
The same clay it can also be applied to cover the floor: it is easily maintained and also suitable for situations of intense foot traffic. For the flooring we also recommend wood, provided it is finished with natural products (based on linseed oil, herbal extracts, natural resins) and with dry laying, which avoids the use of harmful adhesives. Parquet can also be an excellent solution: a solid wood product is better. Make sure it is of Italian or European origin certified for controlled forest management (FSC brand).
Another environmentally friendly component is the eco-sustainable structural concrete, composed of cement and siliceous aggregates. They are low clinker content cements, produced with renewable energies and post-consumer recycled aggregates. Their use contributes to the abatement of emissions of pollutants into the atmosphere and helps to preserve the natural environment.
Another material that meets the biocompatibility criteria is gypsum fiber, a material consisting of a homogeneous blend of high quality gypsum and cellulose fiber. The mixture is added with water and compressed under high pressure, in order to form resistant and monolithic sheets. Thanks to green building a new concept of architecture is born that integrates with the environment, which respects nature and human health, ensuring a high level of living comfort.
