FiberGlass and plastic foams does not conduct electricity or its a bad conductor because:
Glass is mostly silicon oxide, a covalent compound .
Covalent compounds share electrons from each of the constituent elements ( silicon and oxygen) to bond those elements together as a compound; two atoms of oxygen for each atom of silicon. some glasses have additions of ionic compounds.
Conduction of electricity requires some mobility of electrons to move that potential charge through the material.
Electrons in covalent and ionic compounds in glass are too tightly bound to the molecule to conduct electricity.
Therefore, fiberglass and plastic foams does not conduct electricity.
Most metals conduct electricity because metal atoms are bound by metallic bonds that share a “cloud” of mobile electrons that are free to move within the normal crystalline structure

fibre glass and plastic forms are bad conductor of heat as well as electricity because they not allow heat and acetic to pass through them easily
