If your Wisconsin home was built before the 1990s, there’s a chance that your attic could be insulated with vermiculite, a material that was commonly used due to its excellent heat resistance and lightweight properties. Unfortunately, much of the vermiculite insulation sold in the U.S., particularly under the brand name Zonolite, was contaminated with asbestos. This contamination makes vermiculite a significant health hazard, especially if it’s disturbed. In this blog, we’ll explain what vermiculite is, how to identify it, and why you should hire certified professionals like Quality Asbestos for its safe removal.
What is Vermiculite Insulation?
Vermiculite is a naturally occurring mineral that expands when heated, making it a popular choice for attic insulation. It was mined extensively in the U.S., particularly from a site in Libby, Montana. Unfortunately, this mine also contained a large deposit of asbestos, which contaminated much of the vermiculite sold between the 1920s and 1990s.
Vermiculite insulation is often recognized by its granular, pebble-like appearance, which resembles small bits of gravel or mica. It’s lightweight and usually gray-brown or silver-gold in color. If your home contains this type of insulation and was built before the early 1990s, it may very well contain asbestos.
Why Vermiculite Insulation Should Not Be Disturbed
Asbestos fibers are dangerous when they become airborne. If your vermiculite insulation contains asbestos, even slight disturbances—such as moving boxes in your attic or attempting to remove it yourself—can release harmful fibers into the air. Inhalation of these fibers can lead to serious health problems like lung cancer, mesothelioma, and asbestosis.
Because of the health risks involved, it is critical to never disturb vermiculite insulation. Instead, the removal should be handled by certified professionals who are trained in asbestos abatement.
The Zonolite Attic Trust: Financial Assistance for Removal
If your attic contains Zonolite brand vermiculite insulation, you may qualify for financial help through the Zonolite Attic Insulation Trust (ZAI Trust). This trust was established to help homeowners safely remove asbestos-contaminated Zonolite insulation by reimbursing up to 55% of the removal costs.
At Quality Asbestos, we can help you determine if your insulation is eligible for reimbursement through the ZAI Trust. We’ll guide you through the process to ensure that your removal is as affordable as it is safe.
How to Know If Your Attic Contains Vermiculite Insulation
Identifying vermiculite insulation is relatively easy. If you notice a loose, gravel-like material in your attic, especially if it looks silvery-gray or gold-brown, you may have vermiculite. However, you should never try to test or remove the insulation yourself. Instead, contact an asbestos professional who can safely collect samples and send them for testing.
