Eigenleistung:Thermal renovation with straw bales Kundenzufriedenheit:The builder Frank Böttinger writes: Two years ago I insulated the façade of my older farmhouse with straw. Your book was a great source of information for me (until then I had no idea whether it made sense to use straw bale insulation). Since then I have been thrilled about the insulating effect and the design possibilities of the outer façade!

This farmhouse in Bavaria was sheathed with straw bales on the outside, plastered directly (on hare trellis) at ground level, and clad with wooden shingles on board cladding on the 1st floor and gable.
For this purpose, OSB boxes were fixed around the windows and an auxiliary scaffolding was mounted at the distance of the bales.
The bales stand on a concrete foundation strip with horizontal insulation (tar paper), a hare mesh (fine-meshed wire) was used as a plaster base. After the first layer of plaster, PolyesterGittex was applied to prevent cracking.
