Within a recent thread about something else somebody mentioned that double glazing is a rip off.
At the risk of opening a can of worms is that true? I am about to replace a window in our kitchen extension so I am not convinced DG would make a lot of difference anyway.
Is there much to be saved in cost?
I want a window that completely opens like a door, could I even get one of these in single?
Ta.
The figure I used to use was that each reduction in 1.0 of the U value reduced heating costs by £1/m2. That's probably now nearer £3. DG will give a reduction of 2.5-4 depending on the spec, so reckon on something like £10 per m2 per year. With mains gas heating.
So the little pane in my french doors about 600x400 saves about £2.40 a year. It cost £50 (toughened), replacing the two-year old one that caught a mower stone. Bad economics!
Yes but most modern living room sized windows, and bedroom windows too in some cases are about 2m long and 1.5 high, so this is 6m2, per room, per year
But comfort is important and a dg panel will be more comfortable than a single one.
What's good economics about going to the pub or out for a meal or buying a new tv or ... ?

Depends on who you buy it from. Pay the hysterically high "list" price from the likes of Anglian and yes you are being ripped off like there is no tomorrow. Pay their 60% discount price provided the sales man can get clearance from his manager and you sign now then you are only being ripped of. Buy from a well established local company and the prices will be reasonable and the service immeasurably better.
What angle are you looking at it from? Heat loss, comfort, appearance, maintenance?
Depends on the size, particularly the width.
Not really. Most of the benefit from UPVC DG is in draught reduction, lack of maintenance and reduction in condensation.
A SG unit that seals well plus a heavy interlined curtain dies a better job of insulation and looks nicer than DG with net curtains. For example.

Who mentioned bloody horrible UPVC, I've got both well draught proofed single glazed old style sliding sash windows and double glazed versions of same and the comfort level in front of the double glazed is noticeably better.
Why on earth would you want to draw your curtains in daytime?
It might be if you replaced perfectly good single glazing expecting it to pay for itself. Prices vary enormously too.
If the window (and I assume frame - rather than just the glass) needs replacing, the issue changes as having a single glazed window made is likely to cost as much or more than a double glazed unit.
Not quite sure what you mean?
The whole unit opens fully outwards.
AFAIC, the absolute killer is reduction in maintenance. Not having to spend several weekends each summer up a ladder painting those damn stupid "Georgian" window frames makes the decision to fit uPVC a no-brainer. Any other benefits are secondary. As it were.
I've resisted for years, but have been nagged into getting the windows replaced - the frames are rotting and shot
I see no point in not getting double glazing, as I can't see getting the windows replaced with single glazed units would be any cheaper,
or where I might get frames made more cheaply (not the sort of job I'd want to try and DIY nowadays either)

Something you might want to consider is that you can get a lot of condensation in kitchens. I would think that a DG unit would be better in this respect
