Further advantages of a building with HarKun wall elements are revealed when the question is so crucial today about housing insulation.
When using the HarKun single elements, the filling of the insulation and carrier layer can be achieved easily and quickly by simple pouring. This favors the time- and cost-saving (semi-) industrial prefabrication. The formwork required for this purpose can be provided with thin fleeces, reed mats, wickerwork, plasterboard fabrics, clay or wood wool light construction boards or straw mats, which are also used as plaster beams. Even the incorporation of earth-moist material would be quite possible because of the lack of steam brakes and barrier layers.
Natural building materials such as wood shavings, hemp, flax, reed, grasses, straw and other plant fiber materials are therefore particularly suitable as raw materials in combination with some clay, see CAD sectional drawing.
The wind tightness is achieved by compacting as an insulation filling and by the plaster layers. Similar to the straw bale construction, the inner and outer plaster layers are at the same time a very capillary, vapor and air permeable layer for wind tightness.
Still to mention: Unlike the straw bale construction, the HarKun construction is very flexible and is not bound to a specific grid from the outset, as the given dimensions of straw bales bring with it.
