What is U-value?
It simply means that every degree of temperature difference between a hotter air
space and a colder air space, the heat energy will transfer per sq.m to the colder air space.
For example, let say your house has a ceiling area of 100sqm, the difference in temp is
30deg, and the amount of watts you pay for consume is 6000w. Then the U-value is
6000w/100m * 30k=2w/(m *k).
