[TRNSYS-users] Window U value

[amandgal at acciona.es]

Hello,

I use Window 5.2 to create windows to introduce in TRNBUILD.
I make some test and I don't understand why the U value of a glazing change
when I change the order of the layers.
It is obvious that the radiation coefficients change with the order of the
layer but the U value that, for me, is only a conduction-convection
variable, may not change.

If someone knows why the U value varies, please could you explain to me.

Thanks
