First, all modern stove gaskets are made of fiberglass. Fiberglass gasket is available in many sizes, and density. The exact of thickness will depend on the application on the product. A frequently opened door may need a larger, more-dense gasket for a better seal and durability. A glass gasket, for example is typically not large or dense because it is not required to be large, nor is the gasket disturbed very often.
