Rockwool that is inhaled and retained in the respiratory tract can pose a significant health risk. Scarring of internal tissues and the development of cancerous tumors have been associated with long-term exposure to rock wool and other synthetic fibers.

Is rock wool the same as asbestos?

Rock wool (RW) is a kind of asbestos substitute and is widely used in the construction industry, in particular for fire-resisting insulation, thermal insulation, and acoustic absorption.

How can you tell if insulation is vermiculite?

Identifying Insulation That is Made From Vermiculite

Vermiculite insulation is a pebble-like, pour-in product and is usually gray-brown or silver-gold in color.

How do you remove vermiculite insulation yourself?

Just think, if you tried to sweep up dust it flies into the air. But mopping it up ensures it stays put and is easy to remove. A large shop vacuum works best in attics. Line the shop vac with heavy-gauge plastic bags and start sucking up the vermiculite.
