low cancer risk materials to work with?
We believe that putting fibers in to a heat sealed bag to form a pillow is better than letting fibers loose in a ceiling or wall structure. It is too easy for rodents and rats to access such materials. The research is difficult to read and keep up with. A recent study found that very similar fibers may produce different results, but as many as 160 rats per 1000 developed cancer after exposure to thin fibers. There was some correlation with early irritation and later health problems. Of course, it is the thin fibers that are most likely to get into the air through wall spaces or when someone wants to make a repair on any part of a wall or ceiling. Our advice is to wear protective masks and wash up well all clothes and body parts after heat sealing any fibers. Do this work outside where fibers left lying around can biodegrade early. We will bag or seal. Email your requirements. In summer 2003 Cabot has announced it will begin making aerogel beads at affordable prices. For vertical walls
