Info and help with U-Values
If you have a look on YouTube there is a channel called Doodle science - it's a bit brief but covers the basics really well.

Another good channel is mygcsescience - it has videos specific to AQA CORE AND ADDITIONAL science.

U-values measure how effective a material is an insulator. 
The lower the U-value is, the better the material is as a heat insulator. 

For example, here are some typical U-values for building materials:
  • a cavity wall has a U-value of 1.6 W/m²
  • a solid brick wall has a U-value of 2.0 W/m²
  • a double glazed window has a U-value of 2.8 W/m².
The cavity wall is the best insulator and the double glazed window is the worst insulator.

Note that you do not need to remember any U-values for the exam or know the equation used to calculate U-values.

Architects need to know how well different materials will insulate the building they design.  To help them with this they need to know the U-values of different materials.
A U-value of 1 W/(m² oC) means a 1 metre square area of the material with a 1 oC temperature difference across the material will conduct heat at a rate of 1 joule per second. (this definition is not necessary)

U-values measure how effective an insulator something is. The lower the U-value the better the material is at insulating. (This bit is all that you really need)
