Gases possess inadequate thermal conduction Attributes compared to liquids and solids and therefore make excellent insulation materials if they can be trapped. To be able to even further augment the efficiency of a fuel (for example air), it may be disrupted into small cells, which simply cannot properly transfer heat by purely natural convection.
It might be demonstrated that for some units, You will find there's least insulation thickness demanded for an enhancement to become realized.[8]
