Asbestos Contaminated Vermiculite
| Product description | |

|
Not all vermiculite contains asbestos. Only scientific testing will determine if the vermiculite contains asbestos. Vermiculite is a silver-gold to gray-brown mineral that isflat and shiny in its natural state. When heated to around 1000 degrees C, itpops (or puffs up) which creates pockets of air. This expanded form, and thefact that vermiculite does not burn, made the material suitable for use asinsulation and ceilings. Vermiculite itself has not been shown to be a healthproblem. However, some vermiculite insulation contained asbestos fibres due tocontamination at the Libby Montana mine. |
