Vermiculite is a type of insulation that may contain asbestos fibres and is commonly found in older homes with insulation installed prior to 1990. If you suspect that there is vermiculite in your home, it is highly recommended that you take precautionary measures due to serious potential health risks. If exposed, asbestos fibres can become airborne in the home’s interior and cause serious harm if inhaled. For more information about the risks associated with asbestos exposure, please visit Health Canada.

If you discover vermiculite in your home, do not disturb it. Contact a certified asbestos removal specialist that will follow BC hazardous waste regulations for options in relation to your renovations. For information about asbestos testing and having it removed professionally, please visit Work Safe BC.
