Metals, especially those with high thermal conductivity like copper and aluminum, are the best substances for heat transfer by conduction. This is because metals have loosely held electrons that can easily carry and transfer heat energy through their structure.
Metals such as copper and aluminum are excellent conductors of heat and transfer heat efficiently by conduction. These materials have high thermal conductivity, allowing them to quickly and effectively transfer heat from one point to another.
Conduction works best in solids because the particles are close together and can transfer heat energy through direct contact. Liquids and gases are poorer conductors of heat compared to solids.
Convection occurs best in fluids, such as air or liquids like water. This is because fluids are easily able to move and transfer heat through the process of convection. Solid materials do not readily allow for the movement of particles, so convection is less efficient in solids.
A vacuum allows no conduction or convection of heat, but still allows radiative transfer. The radiative component may be blocked by a reflective film. Hence your vacuum flask has a silvered finish to the evacuated double-walled container. Even so. there will still be a small conduction of heat through the necessary thermal bridge at the neck of the flask.

Double-pane windows filled with argon gas between the panes would be best for slowing the transfer of heat through conduction. The gas acts as an insulator, reducing heat transfer. Additionally, low-emissivity (low-e) coatings on the glass can further decrease heat conduction.

Conduction works best in solids because the particles are closely packed together, allowing for efficient transfer of energy through collisions between particles. In liquids and gases, the particles are more spread out, which can impede the transfer of energy through conduction.

The best example of heat energy transfer by conduction is when a metal spoon placed in a hot cup of coffee becomes warm as the heat from the coffee is transferred to the spoon through direct contact.
The best way to stop conduction is to insulate the materials that are in contact with each other. By adding a material with low thermal conductivity between the two objects, you can prevent the transfer of heat through conduction. Additionally, reducing the surface area of contact can also help minimize conduction.
Heat travels in 3 ways. Conduction, convection and radiation. Conduction is the transfer of heat through collision of particles. Convection is the transfer of heat through the movements of particles (ie. hot particle rises, cold particle sinks). Vacuum is made up of nothing (when there is no particle, it is vacuum), and so, it is unable to transfer heat through conduction and convection at all, making it the best thermal insulator
Thermal curtains help reduce heat transfer through conduction and convection by providing an additional barrier between the window and the room. They do not have a significant impact on reducing radiant heat transfer.
Materials with low thermal conductivity, such as fiberglass insulation, foam insulation, or aerogel, are effective at slowing the transfer of heat. These materials create insulation barriers that impede the flow of heat energy through conduction.
