Heat Loss in the Home
Can you use ideas of conduction, convection and radiation to explain how the various types of insulation can reduce heat loss?
Remember to refer back to key words such as 'insulator' and 'conductor' and to try and include as much detail as possible about how the types of heat transfer work.

U Values
We can find the most significant heat loss by looking at U values. A material with a high U value is a good conductor and a material with a low U Value is a good insulator. Power loss (W) = Surface Area (sq. m) x Temperature difference (degrees C) x U Value (W/m2degrees C)
