	ACOUSTICAL SEALANT
	** NOTE TO SPECIFIER ** Henkel Corporation; Acoustical sealant products. This section is based on the products of Henkel Corporation, which is located at: 26235 First St. Westlake, OH 44145 Toll Free Tel: 800-624-7767 Tel: 440-250-7700 Email: request info Web: www.osipro.com/greenseries [ Click Here ] for additional information. Henkel Corporation OSI® Pro-Series® and OSI® GreenSeries™ adhesives and sealants are designed to meet the demanding requirements of the professional building trades. Contractors and Builders know they can depend on Henkel to deliver quality adhesives and sealants for superior results. OSI® GreenSeries™ is the first green brand in the adhesives and sealants category, that meet both energy efficiency and global impact standards. The line offers a full range of green caulks, sealants and adhesives making it easier for professionals and consumers to identify products that can help make homes more energy efficient by preventing air from escaping through cracks. In addition, the entire line of OSI® GreenSeries™ has reduced or eliminated harmful VOC (volatile organic compound) levels, designed in accordance with green building specifications. Currently, fifteen states have passed or are in the process of creating regulations that limit VOC-emissions, and several other states are following suit. The chemicals, which are contained in adhesives and sealants, emit into the atmosphere, resulting in air pollution that can also irritate allergies, asthmatic conditions, and potentially lead to health risks after continual exposure. Two national organizations leading the green building initiative, which have also included criteria specific to the use of adhesives and sealants, are the National Association of Home Builders (NAHB), with their Model Green Home Building Guidelines, and the U.S. Green Building Council, with their LEED (Leadership in Energy and Environmental Design) Green Building Rating System®.
