before you go condemning a project take a sample of what you think is asbestos to a testing facility. soak it with water and a kitchen detergent. place it in a plastic bag and seal it. IF you find out it is asbestos, THEN think about encapsulation or an abatement project. merely covering the stuff with plywood would create problems IF the stuff started to turn into a talc or powder which would go into the house's atmosphere. Encapsulation products are sticky and remain sticky even when cured to trap ANY friable fibers.
