Strawbale Construction Print E-mail

Background:

  • Straw bale building has been around for about 100 years, originating in Nebraska in the USA.
  • Straw bale building is easy to construct and suitable to use with unskilled labour of all ages and genders.
  • Straw bales are an annually renewable agricultural waste product that is often wasted or burnt by farmers.
  • Technical information:
  • Straw bales are dry packed either as in-fill between structural frames or as load bearing walls where a ring beam plate is tied to the foundations.
  • Straw bales are stabilized with horizontal & vertical timber saplings and finished with clay and lime plasters.

Benefits:

  • Straw bales walls have phenomenal acoustic and thermal properties, resulting in a very high level of human comfort, way superior to any other building material available.
  • As the straw is too tightly packed to support combustion and due to its high insulative properties (R value = R6 to R7), a plastered straw bale wall is exceptionally fire-proof.
  • Straw bales are an abundant agricultural bi-product and South Africa currently grows enough straw to provide enough material for 1 million homes every year – more than double the countries present capacity!
  • Straw bales are inexpensive to buy as well as dispose of as all waste can be mulched for landscaping purposes.
  • Building with bales is relatively easy to learn and lends itself to self builders and community involvement.
