Can you buy custom double glazed panels where one edge is a curve? My local place says no. It would be to fit to a Victorian sash. Other similar houses in this street have had the original sash windows which had curved tops replaced with new double glazing complete units which have straight tops - making them look even worse than replacement windows normally do.
Yes, you can - I've seen them being made up at one of our local dg places.
You mean an arched top glass unit? Then yes, easily possible. The place I get mine from (in Leicester) supply any shape and size you require. For some of the ones I do, I just take a cardboard template to them, and they have never failed me yet. Alan.
Well, I've seen it done on Grand Designs, usually in combination with phrases like "specialist supplier", "long delay" and "very expensive". :o)
As the other replies say - easy. I've take a hardboard templates to 2 different glaziers and had them make up curved-edge units. Something like a 20% surcharge above the cost of the bounding rectangle.
Thanks guys - are they horrendously expensive compared to 'square' panels of the same area?
Oooh yes. You're thinking of the curved house in Clapham. The one built around the chestnut tree. The whole glass was curved there and yes, I seem to remember they did say it was expensive. If I understand correctly, what Dave wants is flat glass but with a curved top, not a curved panel so should be a 'little' cheaper.

The difference between the two is huge. Cutting a piece of glass (or two) to a curve can be done by most dg manufacturers. Making two pieces of curved glass, with different radii of curvature, then making a sealed unit out of them, strikes me as a fairly tricky procedure.
I take it you are going to be fiiting this unit toa timber frame? Timber just needs a good joiner, plastic might be harder to do with the fill in pieces required. Curved top plastic windows really have square glass with the curved bit of trim stuck on...
That's exactly what I don't want. It looks cheap and nasty.
So the sealed unit will need to be curved.
Agreed, no option for our only curved top window (used to be a barn door) the stone work is curved. When we enquired about plastic double glazing for that position it didn't pose much of a problem. The sealed units and frame will have to curved on something like a 6' radius.
