Summary

There is a widespread belief that batch raw materials used to manufacture fiberglass insulation can be of lower quality than those used to make other types of glass because fiberglass does not presently have a color or seed requirement. Two batch materials commonly thought to be acceptable for fiberglass when not acceptable elsewhere are purchased plate and container cutlets. This paper explains why strict quality requirements are necessary for purchased cutlets. The quality needs are discussed in light of the current political climate in which usage rates are increasingly being dictated by law. If legislators are to write laws which both meet their social goals and do not penalize the fiberglass industry, a clear statement of the cullet quality requirements in the form of definitive specifications is needed. Efforts to write such specifications are discussed.
