Investigations of HD straw bales so far indicate that they are suitable for using as building
material. The results must be further gone into and added to. It is practical for further use to
use bales with high density (130 to 150 kg/m3) because these offer multiple advantages such
as better insulation and mechanical properties, improved heat insulation capacity and sound
proofing. Following the determination of the properties a straw bale used in building
construction must have, a suitable production can be developed, a sort of standard bale.
Alongside these investigations others, looking further into the associated architecture and
statics as well as straw type, should be followed to ensure optimal application of the straw
bales. All these investigations can also help to achieve a general planning permission for
building with straw bales
