One material that is known for keeping heat inside is insulation. Insulation works by trapping heat within its fibers or layers, creating a barrier that slows down the transfer of heat from one area to another. Common insulation materials include fiberglass, foam, and mineral wool.
White color reflects most of the heat, while black color absorbs heat, making white color more effective in keeping heat away.
Glass keeps heat by being a poor conductor of heat. This means that heat does not easily transfer through glass, allowing it to trap heat inside a space. Additionally, glass can absorb and re-radiate heat, further assisting in retaining warmth.
Silk is a natural insulator of heat, meaning it traps heat close to the body and keeps the wearer warm. This is due to its structure which creates pockets of air that act as a barrier against heat loss.
A thermal insulator is designed to keep heat in or out, depending on the direction of heat flow. It reduces heat transfer by trapping air or creating a barrier that slows down the movement of heat energy.

The skin keeps it in.
Because it traps the heat that comes from your body from escaping, so you have more heat so it keeps you warm.
a good insulator of heat keeps the heat in, so you stay warm
