	For best results, display hidden notes to specifier.
	** NOTE TO SPECIFIER ** Knauf; glass fiber thermal insulation for exterior walls, roofs, and ceilings; acoustical insulation. . This section is based on the products of Knauf Fiber Glass GmbH, which is located at: One Knauf Drive Shelbyville, IN 46176 Tel: (317) 398-4434 Tel: (800) 825-4434 Fax: (317) 398-3675 www.knaufinsulation.com [ Additional Product Data ] This section covers Knauf's batt and blanket, board, blowing, and specialty insulations, for thermal and acoustical applications.
	Knauf makes premium fiber glass insulation for industrial and commercial use, air handling, residential, metal building, and OEM markets. About the time Knauf was started in 1978, the insulation business had become rather predictable and complacent. It was time for change, and that's what Knauf offered: new ideas about performance and quality, innovative products, service, and a 'let's do it' attitude. For the beginning, our customers had the same sort of 'we're in this together' team approach, and it's paid off. Today, Knauf is the fastest-growing manufacturer of premium fiber glass insulation with plants located in Shelbyville, Indiana, and Lanett, Alabama. .
