So what is straw-bale construction anyway? Simply put, it is a post-and-beam system with straw bales; the bales are infill.
Why would anyone do this?
- Well, it's green for one - straw bales are a naturally growing, renewable resource: the post and beam system also uses less lumber than 2x stick framing or steel studs in light gauge metal framing.
- While standard residential exterior wall construction has an R-Value of 20-25 (this is your insulating value), straw-bale has an R-Value of 60.
- What's more is the finish; plaster over straw-bale gives a wavy, organic wall profile. It finishes with true character.
