Wool insulation for thermal purposes is a sustainable choice due to its renewable nature, low embodied energy, and energy-efficient properties. It is non-toxic, naturally fire-resistant, and durable, with a long lifespan, reducing waste. Wool can be recycled or is biodegradable at the end of its life, supporting a circular economy. Its unique carbon-sequestration ability helps combat climate change. Local sourcing, certifications, and energy savings further enhance its environmental credentials, making wool insulation an eco-friendly and resilient option for building insulation.Wool insulation for thermal purposes is a sustainable choice due to its renewable nature, low embodied energy, and energy-efficient properties.
