Mal - my apologies, I've only just seen this as I don't normally look at the property forums.
We've got single-glazed metal windows, which are obviously very inefficient as regards insulation.
If you can afford them, then double-glazed windows are definitely the think to go for.
We decided against it - at our time of life, I doubt we'd live long enough for the capital outlay to be returned in savings.
Personally, I don't like PVC windows - they need metal stiffeners inside them to make them rigid, they tend to be on the chunky side, and keeping the plastic clean can be a pain. However, there may not be any alternative - if you were to ask for aluminium double-glazed windows with a thermal break in the frame (what I fitted in the UK), then people would probably look at you cross-eyed!
