Asbestos or vermiculite? If your home is insulated with an old vermiculite insulation product, it is justified to believe until proven otherwise that it may contain amphibolic asbestos. However, the mere presence of vermiculite insulation does not automatically mean that asbestos is present. Vermiculite is a mica-like ore used in the manufacturing of a wide range of products thanks to its insulating and flame retardant properties. For its part, amphibolic asbestos fibers are very resistant to high temperatures, but are problematic because of their friable nature.

On that subject, did you know that…


…only the ore extracted from the Libby mine in Montana between 1920 and 1999 causes worries


…products for that mine have been used very little since de mid-1980s and have not been available in Canada for a decade


…asbestos isn’t dangerous, except if its fibers are present in the air you breathe


…concentrations of asbestos in the air may vary depending whether you move or break materials containing it


…Health Canada strongly recommends to NEVER remove any insulation containing asbestos yourself


…exposure to amphibolic asbestos can cause asbestosis, mesothelioma and lung cancer


All homeowners whose homes are insulated with vermiculite-based insulation should have a lab analysis of a sample of that insulation. If you fear having or have a problem of vermiculite containing asbestos, there are some precautions to take: :

Don’t let children play in the attic
Inform anyone who needs to access the attic to work
Don’t store anything in the attic if there is any risk of lifting asbestos fibers
If you have to go in the attic, wear a suitable mask
NEVER remove insulation containing asbestos yourself
Seal any cracks, holes or openings between the living areas and thoses containing the contaminated insulation
