Strawbale Construction Resources
I used to know of CREST’s list, Yahoo’s SB-R-Us. There was a strawbale list on pipermail.
None of them seem to be around any more.
There’s one on Reddit, but last post was a year ago.
The Last Straw has a resource list. None of the links to mailing lists work.
So I reach out to the hive mind.
Given the variety of responses, I will clarify my current quest.
I want to make an ice house for storing seedlings in spring. This works. I currently have a shed wrapped in small bales on edge. Inside is lined with used roofing for 3 feet, then filled with 2 feet of snow. This works, but it is not big enough, nor does it keep the snow long enough.
I have a nearby source of large square bales 4x3x8. My plan is to make a 24′ x 24′ interior space (exterior wall 32×32, roof 40×40, or possibly 20 x 32 depending on final site choice, truss and foundation costs.
The problem I’ve not seen addressed is keeping my bales from turning into fetid goo. The normal consensus is that the inside plaster should have a low permeability to water vapour than the outside one. This allows water vapour to escape to the outside, driven by the thermal gradient. But in my case, when in use, the thermal gradient goes in reverse, from the outside in. But the inside during use is at close to 100% R.H. while the outside is typically 20-40% R.H.
During the other 10 months of the year, the room is left open. This generally means during the summer the inside is somewhat cooler than the world, and in winter somewhat warmer. (At present after several days of -25 ish weather, the inside is running 3 degrees warmer, despite a propped open door. This is ground heat.
At this point I am giving serious consideration to not plastering the walls at all, putting in an extra support beam so that I can lift the entire roof up a foot and replace the bales as needed.
