What type of insulation is marketed as eco-friendly and made from cotton?

Cotton batts are marketed as an eco-friendly insulation option because they are often made from recycled cotton, such as reclaimed denim. This sustainable material not only reduces waste but also promotes recycling efforts. Additionally, cotton insulation offers excellent thermal resistance, helping to regulate indoor temperatures efficiently. It is typically treated with a fire retardant to prevent fire hazards, making it a safe choice for residential and commercial buildings.

In contrast, other types of insulation like fiberglass and mineral wool are derived from less sustainable processes and materials, while plastic batts do not exist in the context of insulation products. Understanding the properties and origins of insulation materials helps in making responsible choices for environmentally conscious construction and renovation.
