Yes . Some insulators do allow the flow of electrons but most do not.
Any material that does not allow the free flow of electrons.
It prevents the flow of electricity since they do not have mobile electrons or mobile ions to allow the flow of electricity.
wood is an insulator of heat because its electrons don't allow heat and electricity to flow through them
Marble is an insulator.
insulator

They are not alike at all. A conductor allows for the free passage of electrons throughout its body, while an insulator does not allow electrons to flow through its body.
Isolators.
Glass is an insulator, as it DOES NOT conduct current. It is a material which has no free electrons available to flow as electrical current. Conductors, like copper or aluminum, have free electrons, or electrons in the outer shells of their atoms that are easily knocked loose. These electrons flow from negative to positive when an electrical potential (voltage) is applied across the material. We call the flow of electrons "current".
Something that does not allow current to flow is called an insulator. "Electricity" doesn't flow, only current, which is one aspect of electricity, does. Note, current is the flow of electrons.
Marble is an insulator.
insulator...as opposed to a conductor which does allow electrons to travel freely within it.
