Abstract
A storage silo apparatus having a storage silo including a shell wall, a secondary wall spaced radially outwards from the shell wall, and a space having a first width formed between an outer surface of the shell wall and an inner surface of the secondary wall. An insulation layer located in the space is narrower than the space such that an air gap is formed within the space. The air gap is formed radially adjacent the insulation layer and is configured to resist heat transfer between the shell wall and the secondary wall.
