    Its construction..

    In Physics you dont actually have to calculate U-Value, Only know the definition

    jeese they are trying to help and you couldn't be any less grateful

    do you expect them to route through the entire paper now to find it for you?

    and not one word of thanks to anyone who has helped so far

    You're just dividing the wrong thing
    Thickness is always the first thing to go into the calculator.
