Double glazing should make a significant difference to the internal conditions in terms of both temperature and noise. Noise is not an issue for us were we live, the street is relatively quiet and the neighbours we have are good.
Given the temperatures we experience here in Australia. I don't know why it isn't a requirement for new homes to have double glazed windows, along with solar panels, and a rain water tank. Yes it would add to the cost of construction, but long term the home owner would save.
