In winter, aluminum heat-insulating materials serve the role of aluminum foil wrapped around baked sweet potatoes.

In winter, the low thermal emissivity prevents the warm indoor temperature from escaping. In winter, aluminum heat-reflective insulation acts like aluminum foil wrapped around baked sweet potatoes. Due to the low thermal emissivity of the foil, it helps retain the warm indoor temperature (heat always flows from warmer areas to cooler ones). In summer, the foil installed in the attic reflects heat from the sun before it enters the building, keeping the indoor temperature cool. Additionally, the bubbles sandwiched in the foil prevent heat flow through contact, and since they are solid, they do not cause heat rise and also serve as a moisture barrier.
