These materials are usually more threatening, they become airborne much quicker and must be controlled and contained properly during the removal process. Safety is really important, following the regulated procedures and providing air sample results to prove that you have done so is essential.

Vermiculite insulation is usually found in attics & inside exterior walls of a home, however, sometimes is found in plaster drywall. Vermiculite insulation in attic needs to be tested five times pulling samples from 5 different areas from attic before any removal, that is required to determine if the material is the same percentage containing throughout the attic which most of the time test less that 1%, even though the amount is really low the Minnesota Department of Health recommends to use a Licensed Asbestos Contractor.
Drywall, plaster or ceiling texture always has to be tested as well to see if it contains asbestos. Sometimes it is mixed with vermiculite insulation and other times it is just a thin first coat layer on the front.
