Bubble insulation, also known as reflective bubble insulation or bubble wrap insulation, is a type of insulation material that consists of a layer of small airfilled bubbles sandwiched between two layers of reflective material, such as aluminum foil. It is commonly used to provide thermal insulation in various applications.
The airfilled bubbles in bubble insulation act as a barrier to reduce heat transfer through conduction and convection. The reflective surfaces on both sides of the material help to reflect radiant heat, further enhancing its insulating properties. This combination of reflective and insulating properties makes bubble insulation effective in reducing heat loss or gain, depending on the desired application.
