global transmittance calculation of the frame

[archilinus]

Dear colleagues

I would like to clarify and clarify, a manufacturer of thermal cut fixtures has made me send on my request all the schemes of his fixtures (very precise and detailed) where all the transmittances of the fixtures, subduvise for transmittances of the frames and transmittances of the glass.

the doubt is on the calculation of the nozzle, the overall transmittance referred to the frame, because theproducer gives me the tramittances referred to the side node ( 1.24 w/m2k) and the central node (1.45w/m2k).

application

how do you calculate the transmittance of the frame?

I hope I have exposed my problem well

Thanks :redface:
