No insulation manufactured today contains asbestos. In previous years the types of insulation that contained asbestos included:
Some, but not all, forms of insulation used to contain asbestos. Insulation applied new now does not contain asbestos.
No, masonite does not contain any asbestos.
Gypsum insulation made prior to the 1970s included asbestos as a means of providing increased physical strength and insulation capacity to the product. Gypsum insulation made after the 1980s generally did not contain asbestos.

Asbestos insulation has no characteristics that make it look any different from other forms of insulation intended for the same application. The only way to know for certain whether insulation contains asbestos is to have a sample analysed in a qualified laboratory. Insulation on pipes and boilers is often white and chalky in appearance. Other forms of insulation have different appearances.
Rock wool insulation was a substitute for asbestos insulation. You bought one or the other, not both.
No modern insulation product sold in North America or the European Union contains asbestos.
No. Owens Corning Fiberglas insulation was made with Fiberglas providing the fibrous functions in place of asbestos.
Vermiculite insulation may contain asbestos which is known to lead to cancer and breathing related problem do to breathing in the asbestos which will attack lungs.
Currently it is illegal to add insulation to a home with more than a very small percentage of asbestos. Exposure to these small quantities of asbestos typically do not cause harm and are considered to be safe. Older homes may have asbestos insulation that needs to be removed as these older forms of insulation do present certain health risks.
