Physics - P1 - AQA - GCSE - Energy Efficiency

1. Cavity Wall Insulation

   • Foam in the gap stops convection
   • Foam in the gap stops radiation
   • Insulating foam with air pockets trapped in it reduces conduction

2. Loft Insulation

   • Fibreglass wool reduces conduction
   • Fibreglass wool reduces convection

3. Draught-Proofing

   • Foam/plastic around doors and windows stop cold air blowing and therefore reduce convection

4. Hot Water Tank Jacket

   • Fibreglass wool reduces conduction
   • Fibreglass wool reduces radiation

5. Thick Curtains

   • Thick material reduces convection
   • Thick material reduces conduction

6. U-Values show how fast heat can transfer through a material

   • Heat transfers faster through materials with higher U-values than through materials with lower U-values
