Straw-bale construction is a type of building that uses bales of straw to act as the walls and insulation of a home or other building. straw-bale construction has been used for many centuries and is still used today in some parts of the world. To build a building using straw-bale construction, bales of straw are stacked on top of each other and held together by wooden or metal beams. The bales are then covered in a plaster or stucco to seal in the straw and provide a finished look. The straw inside the bales acts as insulation, which helps to keep the inside of the building warmer in the winter and cooler in the summer. Straw-bale construction is an eco-friendly way of building, since it uses a renewable resource and requires less energy and resources to build than many other types of construction.
