Why is having silvered surface help insulation?

A silvered surface helps insulation by reflecting radiant heat, which minimizes heat transfer through radiation. The reflective properties of silver reduce the amount of infrared radiation absorbed by the insulating material, keeping the interior temperature stable. This is particularly effective in maintaining thermal efficiency in buildings and thermal blankets, where controlling heat loss or gain is essential. Additionally, the shiny surface helps to enhance the overall insulation performance by creating a barrier to heat flow.
