the worst conductors of heat are wood, plastic, rubber, and cloth.

yes and hot too. Insulation is a heat barrier -- it tries to prevent heat exchange between the two sides. Vacuum is the best. Then air. Metals are the worst. ====================

Depends what's in your gravel. In order of best to worst: Sandstone 1 Limestone Concrete Water Soil ref:http://en.wikipedia.org/wiki/List_of_thermal_conductivities
lava
tin or metal
Air is the worst sound insulator as it allows sound waves to pass through easily. Materials like foam, fiberglass, or mass-loaded vinyl are better options for soundproofing.
the worst conductors of heat are wood, plastic, rubber, and cloth.
Metal is the worst insulator of heat and electricity due to its high thermal and electrical conductivity properties. Metals allow heat and electricity to flow through them easily, making them poor insulators compared to materials like wood, plastic, or rubber.
Aluminum is the worst insulator out of aluminum, cork, and wood. It has high thermal conductivity, meaning it allows heat to transfer easily through it. Cork and wood are better insulators because they have lower thermal conductivity, making them more effective at resisting heat transfer.
It is an insulator.

Silver is one of the best conductors of electricity due to its high electrical conductivity. In contrast, rubber is one of the worst conductors of electricity because it is an insulator and does not allow electrical current to flow easily.
