no its plastic.
Wooden boards, iron panels, etc.
because the composition of plastic is such that it is permiable for any diffusion even that water can not flow across the plastic hence iron is much heavy and harder metal so it can diffuse in plastic

it is made because of it is lighter and can hold quite a air as on the other hand metal and iron or other metal are heavy and when you kick it your leg will sting, air will not go in the ball because of pressure and the ball will not go anywhere.
when you coat a metal in another metal you are protecting the inside metal. The metal metal that is being used as a coat must be more corrosive than the 1st metal. For example iron can be coated in zinc because zinc is more corrosive than iron. This is common on a ship, the iron hull is coated with blocks of zinc which will act as a barrier and will corrode instead of the iron. The zinc blocks must be renewed after a period of time however. Other ways of stopping metals from corroding include, chromium plating, coating in paint, oil or plastic.
It is difficult to say without knowing which metal (aluminum, gold, iron, lead, etc) but if we were to compare polyesterene and iron, iron conducts heat about 1000 times better than polyestyrene.In general, the plastic would be a better insulator.
