Conductor
Wood An insulator is a material that does not allow charges to move through it easily.
Materials that allow energy to flow easily through it are called conductors.
Wood.
Anything that is classified as a conductor will allow the flow of electrons.
That would be an insulator. A few examples include paper, glass or Teflon.
insulator...as opposed to a conductor which does allow electrons to travel freely within it.

Wood.
A thermal insulator. The best is a vacuum, but static air is good, if it can be contained in a mat of fibres for example.

titanium for one thing also maybe metal if there was enough

You may be thinking of the term permeability, which is used when measuring a porous material's ability to allow fluids to pass through it.Hydraulic conductivity describes the ease with which water will flow through pores and fractures, and is influenced by the permeability of the material.
