Is felt or paper a better insulator

Felt is generally considered a better insulator than paper. Felt is typically made from wool fibers that are tightly packed together, creating a dense and thick material that is good at trapping air and preventing heat from escaping. Paper, on the other hand, is much thinner and less dense, making it a less effective insulator. Additionally, paper is a more flammable material compared to felt, which can also affect its insulating properties. Overall, felt is a better choice for insulation purposes than paper.
