Radiation can travel through empty space. The radiation in question is electromagnetic waves.
Conduction, Convection, Radiation
The three main methods of energy transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles, convection involves the movement of fluids to transfer heat, and radiation is the transfer of energy through electromagnetic waves.
For conduction and convection we need a material medium. But for radiation such a meaterial medium is not necessary. So in free space radiation can pass through easily.
Conduction and convection badly needs material medium but radiation does not need a material medium as an essential one. It could traverse even in free space in the form of electromagnetic waves
Heat can be transferred in 3 ways: Conduction, or through direct contact, Convection, or transfer of heat through a fluid, or Radiation, or heat transfer through space in the form of electromagnetic waves.
The three forms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.

actually the insulator is the dead air in the pores a better insulator is vacuum (only radiation) air has conduction convection and radiation air is easier to handle near sea level
