• Crocidolite

This asbestos has straight, needle-like fibres and the drainage properties of Amosite. Its tensile strength is greater than Chrysotile and it can also be spun. Therefore its uses include rope, insulation, steelwork spray protection and occasionally in cement boarding.

Vermiculite Insulation Information

Found in various forms and used for many applications, vermiculite insulation products range from fine particles to large pieces nearly an inch long. Vermiculite attic insulation is a pebble-like, pour-in product and is usually light brown or gold in colour.

It should be noted that prior to 1990, much of the world’s supply of vermiculite came from a mine in Montana. This mine had a natural deposit of asbestos which resulted in the vermiculite insulation being cross-contaminated with asbestos. Attic insulation that uses fibres from the Montana mine may contain asbestos and be hazardous to your health. Contact the Clean Air Services team today for an on-site inspection to learn if your property contains asbestos or other hazardous materials.
