Sorry I hit the wrong button, didn’t mean for you all to get the newsletter  

BUT... because of our concerns under the different climate conditions here in Australia we met up with the leading strawbale builders in Germany to investigate what recommendations are coming from overseas.

They have been rendering half the house in clay and then the side of the house which cops the bad weather in lime, then paint the whole house in the one colour so it all looks the same. As well as this the latest strawbale film documented that they render the bad weather side with 60mm of render, not 35/40mm. 

On the other hand we also met with the Dutch strawbalers to purchase and bring into Australia the first strawbale screws in order to investigate options such as using cladding as a protective exterior. We have one project in Kiama where the wind and rain was so intense that water started coming through window frames and washed the internal clay render away. 

For us this is a big issue and a big problem we want to solve with additional cladding. We’ll keep you updated!

Hallo David, how wonderful to work at Esalen Institute. When building at the Atlantic coast in Brittany, I used an external lerch cladding with 5 cm airspace between the limerendered strawbale wall (structure I-beams). This works fine after 10 years and many storms with horizontal rain and high humidity. 

Surement fun in Big Sur,

Martin Oehlmann

  Hello GSBN: 

  We're working on a housing project for the Esalen Institute in Big Sur (on the California coast, south of Monterey, right on the ocean).  We've discussed using straw bale panels for the exterior walls (and possibly party walls) of these multi-unit buildings.  One of the structures will be located only meters away from the bluff above the ocean.  Yes, beautiful, but sometimes very foggy, and heavy rains with high winds at times, too.  

  Morning humidity in the middle of winter averages around 90%, dropping to less than 70% in the afternoon; summer averages range from 70% to 33% (it's 55% at this moment, fyi).  Our structures will have 3' to 4' (1 meter +)overhangs to the west, north and east, and 6' to 8' (2 meter +) toward the south (and no bales on the south walls).  All sites receive a good amount of sun (no significant trees or hills).  

  Curious to know if anyone has any experience building with straw in similar conditions, and if so what insights you might have to offer.  

  We're also exploring hemcrete and some other systems, but panelized bale walls are our first choice.  Sheathing the exteriors with a rain screen is an option we're also considering.  

  Thanks in advance, 

  David Arkin and Anni Tilt and Team
