Metals are actually good conductors of both heat and electricity... but silicon is a semi-conductor.

Unlike metals, which are good electrical and heat conductors, crystalline solids such as diamond and semiconductors such as silicon are good heat conductors but poor electrical conductors. This is their nature... you can't change it :-)

Silicon is a semi conductor in normal temperature. At high temperature it becomes conductor rather than a semiconductor.
