The discussion centers on the calculation of insulation properties at a pressure of 1 bar, which is equivalent to atmospheric pressure, thus not representing a vacuum. Dave inquires about a formula for determining insulation effectiveness, but the consensus is that no universal formula exists. Instead, heat transfer calculations must consider factors such as convection, conduction, radiation, geometry, and material properties.
