Insulators does not allow current (i.e. Electrons) to flow through it.

Valence band:In the energy band electrons are in the outer most of the orbit.
Conduction band : in energy band solid which is partially occupies the electrons.

What is meant by valence band and conduction band ?

But then why insulator is been called electronics material here ?

Because insulator has high resistivity so it has low conductivity so insulator has very low electron flow.

Conductor- Allows the flow of Electron.
Insulator - Opposes the flow of electron.
Semiconductor - Sometimes allows or opposes the flow of electron.
Insulator - Opposes the flow of electron.
Semiconductor - Sometimes allows or opposes the flow of electron.

Consider current as peoples getting down from a bus.
Conductor - bus having 2 doors
Semiconductor- bus having only one door
Insulator- bus having no doors :)
Conductor - bus having 2 doors
Semiconductor- bus having only one door
Insulator- bus having no doors :)

Insulator have high resistance. So current is zero.

For insulator the depletion region width is hagh between the valance band and conduction band. so there is no flow of free electrons.
