overkill for just measuring the U-values of specific materials.
Personally I don't know any way to measure U-values directly with a
hand-held instrument, but it seems such a device wouldn't be hard to put
together with a data acquisition unit and a couple of
thermocouples.</SPAN></FONT></FONT></FONT></DIV>
