Medical and environmental experts don't agree on what kind of health problems fiberglass can cause. Specialists are willing to call it the culprit for certain specific woes such as skin irritation and some minor respiratory trouble.

Because it's not known to cause cancer, fiberglass does not merit the same intense study as asbestos, another common insulation fiber that long was thought to be benign. According to the Web page of the Environmental Research Foundation, the dispute goes back 60 years. That same year, another investigator reported finding 'no hazard to the lungs' of workers exposed to glass fibers in the air. All five of them developed severe coughs. Additionally, Murga has suffered multiple bruises on her legs, loss of warmth and circulation in her feet, sweating on her arms and a dark discharge from one of her breasts.
