Thermal insulation is the method of inhibiting the transfer of thermal energy from one area to another. In other words, thermal insulation can keep an enclosed area such as a building warm, or it can keep the inside of a container cold.
Heat is transferred by from one material to another by conduction, convection and/or radiation. Insulators are used to minimize that transfer of heat energy. In home insulation, the R-value is an indication of how well a material insulates.
That's Why airplanes insulate heat.
Thank you, Good Luck
We insulate lofts because heat rises, so if you dont insulate the loft all the heat will escape. So if you put the heating on, and your loft is insulated, the heat will rise but stay in and not escape.
Silicone is a poor conductor of heat, so it does not transfer heat efficiently. It has low thermal conductivity, which means it can insulate and reduce the transfer of heat energy. Additionally, silicone's resistance to temperature extremes allows it to maintain its insulating properties even at high temperatures.
Fabrics insulate heat on cups of hot water by trapping a layer of air between the fabric and the cup. This air acts as a barrier, preventing heat from escaping quickly. Additionally, the fabric's density and thickness can also play a role in insulating the heat.
Clothing and body fat help to insulate your body from the cold by trapping heat close to your skin. Shivering can also generate heat to help maintain your body temperature.
Curtains help insulate a house by acting as a barrier between the window and the room, preventing heat transfer. Thicker curtains can create an additional layer of insulation, reducing drafts and heat loss in the winter, and keeping out excess heat in the summer. Closing curtains at night can also help trap heat inside the room.
They would normally insulate the table from the heat of the plate, otherwise there isn't much point having them!

because it is not made of plastic or metal.
Yes, because of the voids (air spaces).
foam has better heat retention

They are poor conductors
yes and no it depends on what wool and what you want to insulate ?
Styrofoam can insulate heat well, hence it is often used to store food.
