A homeowner is going to replace his old single-glazed windows with new double glazed windows.

Discuss the cost of fitting double glazing using better insulating glass compared with double glazing using normal glass.

Use the information given in the tables. (3 marks)

I found this question in a past paper but I can't find the mark scheme for it: (Physics P1 Higher Tier. Wednesday 20th June 2012) and it would be really helpful if you could let me know.. Thanks :)

The lower the u value the better the insulator so better insulation costs more and increasing the gap between the double glazing windows increases the cost
