Straw bale is a building material made from compressed straw, typically from crops like wheat or rice. It is often used in construction for walls, insulation, and even roofing. Straw bales are eco-friendly, renewable, and provide excellent thermal insulation, making them a popular choice for sustainable building practices. In addition to their insulation properties, straw bales are also cost-effective and can be sourced locally. They can be used in various construction methods, including straw bale construction, which involves stacking bales and applying plaster or other finishes. This technique has gained popularity in green architecture for its low environmental impact.
