I explained to them that it might or might not have asbestos. I told them that what I normally see is newer insulation installed on top of the vermiculite and that is OK to do. I also explain why they shouldn't store anything in the attic, how they should use caution if cutting into the ceiling(to install can lights for example). Then I attach a link for them to read up on it a bit more. I don't sweat the vermiculite. I had a previous client test the stuff in her attic and it was clear, no asbestos. Here is the actual report wording; "Vermiculite is a naturally occurring mineral that has the unusual property of expanding into worm-like accordion shaped pieces when heated. The expanded vermiculite is a light-weight, fire-resistant, absorbent, and odorless material. These properties allow vermiculite to be used to make numerous products, including attic insulation. EPA and ATSDR strongly recommend that homeowners make every effort not to disturb vermiculite insulation in their attics. If you must go into the attic follow these basic rules; 1.Make every effort to stay on the floored part of your attic and to not disturb the insulation. 2. If you must perform activities that may disturb the attic insulation such as moving boxes (or other materials), do so as gently as possible to minimize the disturbance. 3. Leave the attic immediately after the disturbance. 4. If you need work done in your attic such as the installation of cable or utility lines, hire trained and certified professionals who can safely do the work. 5. It is possible that vermiculite attic insulation can sift through cracks in the ceiling, around light fixtures, or around ceiling fans. You can prevent this by sealing the cracks and holes that insulation could pass through. 6. Common dust masks are not effective against asbestos fibers.
