Some environmental experts believe up to 16 million homes contain vermiculite insulation, a product that may contain asbestos. When homeowners are discovering that this potentially dangerous product is insulating their home, they often want to take off immediately.
But the EPA suggests that disturbing vermiculite insulation may actually be more dangerous than to leave it alone.
vermiculite insulation is loose fill insulation. You can distinguish it from other types of bulk insulation by his looks. Most other insulation bulk - such as cellulose, fiberglass and rock wool - is fibrous and fluffy. Vermiculite, however, is packed and looks a bit like a worm
Not vermiculite is dangerous - often .. You will find vermiculite in the ground and the brake pads potting
However, most vermiculite sold as attic insulation between the years 1920 and 1980 came from a mine near Libby, Montana, where there is a natural deposit of asbestos. (See the New York Times to obtain information on cases of mesthelioma and cleaning associated with mine).
If you discover you have vermiculite insulation that does its job, and you must not disturb him, then EPA suggests leaving alone. Asbestos removal can be dangerous, and it is often costly because it means hiring professionals. EPA also recommends sealing the openings between the attic and the house, as you might find the devices around the light or heating ducts. (Visit the EPA website for information on vermiculite insulation).
If you have vermiculite insulation, you can have it tested by a reputable laboratory to see if it contains asbestos. However, the EPA says that these tests are not always accurate, and they recommend assuming that the insulation contains asbestos.
If you decide to leave your undisturbed vermiculite insulation, you must stay on the attic to minimize the risk of exposure to asbestos. If you must go into the attic, make sure to stay on the floor and try to avoid disturbing the insulation.
If you want to add more insulation, you might be able to do yourself, but if you want to replace the insulation, you will need to call professionals with asbestos current training and expertise.
