Straw Bale Construction

Straw Bale Construction

In this mordern day we primarily construct building with materials that retain a single life use, Meanning at the end of its course the materials remain unstablke and unrecycled. Example of said materialsare concrete, Various naterialsand asphalts. If you look back far enough the industrial revolution, you would find house with walls builts out from straw bales, Though straw today is used as a biofuel and confactionning verious subjects, it can also be used to be as a very ecologhycal and effective construction materials.

While straw has been to creat housing in Africa since the paleothitic eRA, Its seaing a modern with the rise in popularity of straw bale construction. This affrodable and sustanable means of building being discovered by moderns builders and home ownsers accross the globe with some stand out land mark assisting its rise to prominance.



How to Build With Straw:--

The methode of building a straw house is very different to that of our own , from the bottom up a foundation the width of a bale must be poured in place to support the straw walls. When straw was baled , you obtain rectangular of veried diamensions between (915mmX455mmX355mm) These rectanguar are straw like lego block upto the desire height, are wood rod are inserted at each 5 to 6 layers of straw in order to anchore each bale together , because straw is a organic material containning air, the exterior and interior finished must albe composed of 100% organic materials to allow the wall to prespire, this said materialstypically a coconation of clay sand and straw , by adding water to all this material you create a mud li8ke mix that is easy manupulatable and smooth when dry. The roof it self typically roof truss construction because of the structural ingradient and high stability of the straw wall, the roof can simple rest on and be anchored to the walls.




History of Straw Bale Construction:--

The history od straw bale constructions has a strng foundation in the 1700's but date much further back in africa during the paleolithic era . Germany and France in the used straw as a mean of construction various buildingthat can even still be visited today, In century ago in Nabraska the rapiud evolution of farming equipment pushed the use of straw construction of building house, chuches and even museums, Today there are a modest amount of architects that specilized in straw bale constructions homes, pushing the boundary and what can be accompolished with the materials. 






    Advantages of Straw Bale Construction:--


  • Straw bale are made from a low cost products.
  • Straw bale are 100% biodegradable.
  • With good maintance straw bale are very durable.
  • Straw bvale have a low embodies energy.
  • Insulation valve of R-30, R-35 can be achived.
  • They are relatively easy and cost efficient to install.

    Disadvantages of Straw Bale Construction:--

  • Moisture and mould are significant risks. 
  • Wall thickness means that more of the building overal floor space is unusable.
  • Bales must be kept dry to avoid compressive stress.
  • As it is not a conventional building materials.
  • Straw dust can cause difficult for people with allergies.
  • Fire is also a risk , because of the density of bales , fire trends to smoulder rather than sprade when a igniations sourced is removed.
