[TRNSYS-users] Reflective insulation

[Yossef Ibrahimi]

Hi,
I try to model a roof with an "air gap" and "reflective insulation", but It's not possible to specify the longwave emission and the absorptance coefficient for each layer (TRNSYS 17).Shall I create a zone with a height=air gap above the roof, and use the carachteristics of the reflective insulation for the back side of the roof and front side of this aditionnal zone ?
Best regards,Yossef
