In this video, we’re going to cover another alternative method of construction - building with straw bales! I was surprised to learn that they have a lot of advantages over traditional construction. Straw bales are a resilient and sustainable building product that can help us build better. So, let’s discover how straw bale homes are made, their advantages and disadvantages.

A load-bearing house uses straw bales as the primary structural support. The roof sits directly on compacted bales. A non-load-bearing straw bale house uses another material, like wood, for its primary support. Straw bales are used in between the studs, or as a continuous wall. The construction of a straw bale home is fairly easy and straightforward. It starts with a concrete foundation and wood sill plates. The bales need to be raised several inches off the ground so that they don't soak up moisture from the ground. They are stacked in running bond courses to form the walls of the house. They can be anchored together with wood, bamboo, or rebar stakes so they don’t fall over during construction. Once complete, the walls can be secured with a wire mesh. A moisture barrier is then applied to the surface of the walls. Advantages. The first is that straw is easily available in most parts of the world. The materials for plaster like sand, clay and mortar can be found at building supply stores. Straw bale construction is also fairly cheap compared to other, more engineered building products and insulation materials. They can be good insulators with an average R value of 2 per inch, so an 18 inch thick wall has an R value of 30 to 35. They can also reduce sound transmission and they are earthquake and wind resistant. Straw bales have three times the fire resistance of traditional walls. Since bales are tightly packed, there isn’t enough airflow to sustain a fire, so they are an excellent choice in areas prone to wildfires. The manual labor required to build these houses was something I was concerned about, until I discovered prefabricated straw bale panels. EcoCocon makes panels with compressed straw sandwiched in a wooden frame. They are usually used with an air-tight, but vapor open membrane and a continuous wood fiber board. Disadvantages. The low material cost is offset by high labor costs. Manually plastering walls can make the building just as expensive as conventional construction. The high space requirement is another disadvantage. While a stick frame wall is 6 inches thick, a straw bale wall is around 18 inches thick. You will lose square-footage because of the thickness of the bales. The permitting process can also be tricky. Many design and building codes don’t allow straw bale homes or limit their construction. Moisture is the achilles’ heel of straw bale homes. Straw will decay and weaken if it becomes damp. Moisture can come from cracks in the plaster, plumbing, windowsills or joints that have not been properly sealed. Moreover, bales must remain completely dry during construction. In conclusion, straw bales systems are a surprisingly eco-friendly method of construction. They are more energy efficient, fire resistant, soundproof and durable. But, they require care and maintenance. -------------------- SOURCES:    • Silly Symphony - The Three Little Pigs      • Basket Making at The Goodlife Centre      • Traditional way of making a mud hut .      • Straw Bale House Walls | Part 3      • University of Michigan Professor Joe ...      • #strawbale #strawbalehouse Straw Bale...      • Destruction Testing Clay plaster/ str...   http://thesustainablehome.net/the-ori...    • Natural Passivhaus in Smelynes, Lithu...      • Timelapse - erecting EcoCocon walls i...      • #strawbale #sustainable Day 37: Time ...   -------------------- Fluffy by Smith The Mister https://smiththemister.bandcamp.com Smith The Mister https://bit.ly/Smith-The-Mister-YT Free Download / Stream: https://bit.ly/stm-fluffy Music promoted by Audio Library    • Fluffy – Smith The Mister (No Copyrig...   --------------------- Disclaimer: This video was sponsored by Brilliant" anywhere in the video description box.
