Wool insulation is made from sheep wool fibres that are either mechanically held together or bonded using up to 12% polyester to form insulating batts and ropes. Batts are commonly used in timber-frame buildings and ropes are primarily used between the logs in log homes. Wool insulation is used for both thermal and acoustic insulating applications. Sheep wool is a natural, sustainable, renewable and theoretically recyclable material that does not endanger the health of people or the environment. Wool is a highly effective insulating material that has been used for years insulating people in the form of clothing. Mongolian nomads also used felted and woven sheep wool pads as an insulating layer on the walls and floors of their dwellings called, ger or yurts. Presently the use of wool for insulation is starting to rise in popularity. It is used more in Europe, Australia and Canada than it is the United States; manufacturers are, however, trying to expand their distribution to the US.
