Straw building techniques that use straw bales will, inevitably, give a minimal wall thickness related to the bale size. In the sports hall renovation project at Tilburg, with 1 000 m² wall, this could lead to higher costs and performance than required.
An Austrian farmer (Sonnenklee) was making modifications to an existing baling machine that would produce straw bales at the required size. This could be the solution to building a wall of the correct thickness. However, when informed about the bale sizes, we also learned they were producing straw to be blown in. With blown-in straw the wall dimensions are much freer and more customisable than with bales.
We visited Sonnenklee to learn about the customised baling machine and the blown-in straw.
This visit was combined with a one-day (...)
