Selection of ecological building material

As described above, an open construction with natural building materials is less sensitive, robust and future-proof in the long term. The basic construction of a building envelope, as described in the description, offers the possibility of achieving an unspectacular shift in the selection of materials in favor of the natural, renewable, reusable and later compostable materials without shaking modernity.
Particularly advantageous: the material suitable for HarKun wall elements can be directly used and combined as a scarcely altered raw material without complex prefabrication. Examples which may be mentioned are:

Plant fibers of different length and quality

of straw, wood, hemp, grasses, foliage, flax, cork, reeds, cotton, sea grass, chinagras, maize, grain fur, peat, mosses, lupines, roots, algae, bark, jute, sisal, coconut, cherry cores, willow , Pelts, boards, planks, slats, pallets, wood-fiber fiber boards, hemp insulation mats, paper-cellulose, wood-fiber boards, Ropes, ect.

Produced by vegetables
such as starch, gluten, tree resins, lignin, vegetable oils, coconut fat, carnauba wax, ect.

Animal or animal derived materials
such as animal hair, leather, wool, intestines, milk, casein, whey, horn, bone, dung, fish bone, shellac, beeswax, wool fat, etc.

Mineral substances
such as clay, lime, gypsum, concrete, kieselguhr, limestone, ash, earth pigments, iron oxides, slate, sandstone, granite, pumice, marble, river gravel, sand, silicates, field stones, trass, lava, etc.
