The insulating capacity is influenced by the internal heat transfer hi, the heat transfer in the cavity l, which can be divided into 17% heat conduction, 17% convection and 66% radiation and the external heat transfer h. so that the U-value can be calculated according to the standard DIN EN 673 [1] (11.2).
