Si is not an insulator. It has a unique property in their electron structure- each has 4 electrons in their outer orbital forming perfect covalent bonds with 4 atoms and creating a lattice.

si has 14 electron in the fround state,of these four are valence electron hence it can complete its octet and obtain the stable noble gas configuration of argon.

Silicon is an intrinsic semiconductor. The energy gap between valence and conduction band is low compared to insulators. on heating the valnce band electrons are excited to conduction band, thus facilitating conduction.
