These days, there are a number of great options for residential insulation on the market. However, in decades past, perlite and vermiculite were two of the most common forms of insulation. In some cases, these outdated materials may need to be upgraded or removed. Here’s a closer look at perlite and vermiculite insulation and the main differences between them.

Perlite

This material is composed of volcanic rock, and it's naturally moisture-rich. Small pockets of air inside the rock are excellent at preventing heat transfer. You might find perlite insulation in your attic, along the underside of your roof, or inside your walls. Instead of foam or panels, perlite insulation looks like small, white, loose-filled granules. Perlite can also block out a certain degree of fire and noise.

Vermiculite

This material can be used in everything from soil additives to attic insulation. It was commonly used as residential insulation in properties built between 1940 and 1990. Like perlite, it is also loose-fill insulation, and it was commonly poured onto attic floors. Appearance-wise, it can be described as small, irregularly shaped chunks of light brown, silver, gold, and white. 

Unfortunately, the majority of American vermiculite insulation came from a mine in Libby, Montana, and contains asbestos. If the particles are disturbed, they may enter your indoor air supply, and they can cause lung cancer and other diseases if inhaled. Therefore, if you suspect there is vermiculite insulation in your home, you should reach out to an asbestos abatement team right away.
