Yes, that is their purpose.
Things which keep warm things warm and cold things cold are referred to as insulators.
Insulators are materials that don't transfer thermal energy easily. They have low thermal conductivity, which means they resist the flow of heat, helping to keep objects warm or cool by preventing the loss or gain of thermal energy. Examples of insulators include wood, plastic, and rubber.
Materials with high thermal resistance such as foam, wool, or fiberglass are commonly used as insulators to keep things warm. These materials trap heat and slow down its transfer, helping to maintain the desired temperature inside. Depending on the specific application, the best insulator may vary.

Thinsulate is an insulator. It is a type of synthetic fiber thermal insulation that helps trap and retain body heat to keep the wearer warm in cold conditions.
Conductors carry thermal energy through, but insulators prevent the movement of heat energy. The usual reason is the way the electrons in these elements and compounds are organized, because electrons are the energy carrier, either for heat or electricity.
Materials such as fiberglass, mineral wool, and foam board are commonly used as thermal insulators due to their low thermal conductivity properties. These materials help reduce the transfer of heat, keeping buildings cool in the summer and warm in the winter. Additionally, aerogel and vacuum insulated panels are considered some of the best thermal insulators with very low thermal conductivity.
Insulators work by preventing the transfer of heat through conduction, convection, and radiation. They have low thermal conductivity, allowing them to trap warm air inside and prevent the cold air from penetrating. This barrier helps maintain a steady temperature by reducing heat loss or gain.
To keep themselves warm. (insulation is taken from insulate)
if you shred the paper then it will contain pockets of air within its self (air is one of the best insulators)
They are called thermal insulators or materials with high thermal resistance.
