The equivalent heat conductivity was calculated as per the ift WA-17/1 guidelines. The representative Psi values were calculated under the conditions laid down in the ift WA-08/2 guidelines.
Psi value: linear heat throughput at edge of glass [W/mK] as per EN ISO 10077-2:2012-06
* corresponds to conditions in DIN 4108-3
External temperature Ta: -10℃ Internal temperature Ti: +20℃
