Vermiculite Insulation Containing Asbestos
Vermiculite is a naturally occurring mineral that is mined around the world. From the early 1920's to the mid-1980's, vermiculite was used as cheap, easy-to-use housing insulation, but has not been sold for that purpose since 1990.
It has been recently discovered that certain batches of vermiculite insulation sold in Canada may contain trace amounts of asbestos. When breathed in, asbestos dust can cause serious lung diseases and cancer.
If left undisturbed and enclosed behind a wallboard, a floorboard or in an attic, there is very little risk to health. Never attempt to remove vermiculite insulation yourself. Consult a professional contractor who is certified for working with asbestos before attempting to remove or dispose of the product.
