What is the difference between cast and plaster?

Casts are partly made from fiberglass or plaster, which form the hard layer that protects the injured limb and keeps it immobilized. Fiberglass has several advantages compared to plaster. It weighs less, so the cast made from it will be lighter. More durable and porous, fiberglass allows air to flow in and out.
