Something is not right here. The u-values you have reference to here are those typical for an unfinished steel building, such as a grain silo or hangar bay. Single pane glass windows have a u-value around 1.2, double pane windows are around the same value as bare drywall at 0.5-0.7 Watts per square meter per degree Kelvin...

Thanks for the clarification, the u values i used where mentioned in the paper I mentioned in the previous reply and it could be not precise.
I think it worth to find the materials specifications and calculate the R value for the structure.
