| has gloss | eng: Wool insulation is made from sheep wool that is mechanically bonded together 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, recyclable material that does not endanger the health of people or the environment which is 0.3 to 0.6 points higher than fiberglass, cellulose, or mineral wool .The crimp also allows the wool to retain its structure and overall thickness instead of breaking down and settling like many other insulating materials. Wool is a hygroscopic material which means that it will absorb up to 30% to 40% of its own weight in moisture without becoming wet to the touch . This moisture absorption is unique to sheep wool and does not compromise the wool's insulating abilities unlike cellulose or fiberglass insulation. When used as acoustic insulation wool provides rates starting at 44dB for a 60mm (2.4in) thick partition, and goes up to 53dB for a 100mm (4in) thickness . |
