Question 1

what are the five ways of insulting the home?

Answer 1

1. Cavity Wall Insulation
2. Loft Insulation
3. Draught proofing
4. Hot Water Tank Jacket
5. Thick Curtains

Question 2

What is cavity wall insulation?

Answer 2

Cavity Wall Insulation is foam squirted into the gap between the bricks which reduces convection and radiation across the gap. Pockets of air in the foam reduce heat transfer by conduction

Question 3

what is loft insulation?

Answer 3

Loft Insulation is a thick layer of fibre glass wool laid out across the whole loft floor which reduces conduction and radiation into the roof space from the ceiling

Question 4

what is draught proofing?

Answer 4

Draught proofing is strips of foam and plastic around doors and windows to stop draughts blowing in

Question 5

what is a hot water tank jacket?

Answer 5

A Hot Water Tank Jacket is lagging such as fibre glass wool to reduce conduction and radiation

Question 6

what are thick curtains?

Answer 6

Thick Curtains are big pieces of cloth that cover the window to reduce heat loss by conduction and convection

Question 7

what is specific heat capacity?

Answer 7

How much energy devices can store
