Cotton

Cotton insulation, also known as agricultural fiber, is available in blanket form and is installed in the same manner as fiberglass batts. This material has been produced for years, but develop­mental and marketing strategy changes have not allowed this product to gain a significant foothold in the residential market. Cotton insulation was developed originally as Insulcot by a small West Texas company using virgin cotton. Promoted initially as a nonirritating alternative to fiberglass, early market research revealed a consumer interest in the use of recycled fiber, and the company switched to mill scraps from denim and T-shirt mills. The developer eventually licensed production of the insulation to Greenwood Mills, a large textile manufacturer.9 This was discon­tinued in late 1997 due to the excessive cost of production.17 Inno – Therm Products, LLC, has now purchased the equipment and technology for manufacturing batt insulation out of recycled cot­ton fabric from Greenwood Cotton Insulation Products. Inno – Therm expects to begin commercial production of the insulation in 2000. The company is planning to pursue both automotive and building insulation markets, focusing initially on commercial building applications.18
