While fiberglass is a useful and inexpensive insulating material, pulmonary maladies and skin irritation associated with its use make it less desirable to work with or have around in homes and building with children. As previously encountered with asbestos insulation, these issues have created an impetus to actively seek alternatives to fiberglass home insulation. Recently we studied relative R values (thermal resistance) of different nonwoven vegetable fiber composites in a radiation cube with the heat source located at the center. These values per inch thickness of material are the following: cotton 3.8; fiberglass 2.2, jute 4.0; and kenaf 4.4. In addition to these results, in this paper we will discuss new home insulation design criteria, novel sucrose-based adhesives for making flexible non-woven composites adhered to dissimilar substances, and the nature of nonwoven vegetable fiber materials as they affect heat transfer.
