Can anybody tell me what the correct terminology is for the bits and
pieces that make up a UPVC window.
I have a bay window, would the terminology be something like
A frame and cill with
1 off large lower fixed casement window, 1 off lower side fixed
casement window and 1 off lower side hinged casement window
with a transom going all the way across with
1 off large upper fixed casement window, 1 off upper side fixed
casement window and 1 off upper top hinged casement window
A casement is a hinged opener, so there is technically no such thing as a
fixed casement, although it would be widely understood. The correct name is
I would describe your setup something like:
Left panel, single horizontal bar fixed lights.
Centre panel, single horizontal bar fixed lights.
Right panel, single horizontal bar, upper top hung casement, lower side
Most importantly, I would draw a sketch, using triangles correctly to
indicate the hinge positions. You should also state your preference for
horizontal bars as being spacers or full bars.
Finally, besides the fact that I wouldn't consider uPVC in any case, the
window you appear to have specified will look odd, being non-symetrical and,
depending on the sizes of the side panels may provide inferior rapid
ventilation and fire egress. You should consider openers in the main panel.
Note that opening windows will look considerably different to fixed lights.
Given the spec, I would hazard a guess that it might be a Victorian or
Edwardian residence (I may be wrong). If so, consider reinstating the
original sash windows. The cheapest we have found for supply only is "box
sash willys". http://www.box-sash.co.uk /
And if that guess is right, repairing wood windows by replacing
sections of wood is usually cheaper than putting upvc in
And realise that upvc sometimes reduces resale value of old houses,
since its so damn ugly.
I know it might sound strange, but
Would a hinged opener be held in a seperate frame (that houses the
hinge fixings and catch mechanism), and that be fixed to the main
And then would a fixed window be held in a seperate frame, that is
also fixed to the main frame ??
Its just the way the 'trade' does it. I hate it.
But its most commonly spelt that way by architects and so on.
Gosh,. This American spell checker can't cope with 'spelt' either.
I couldn't believe it when listening to a very old episode of Cagney and
Lacey to hear them say 'burglarize;' with a straight face. I assumed it
was Noo Yawk slang, till I discovered its standard US usage..
==================Nothing to do with terminology but....................
One detail to consider very carefully is the position of the transom. UPVC
sections are usually much wider than the wooden ones they replace and this
reduces the glass area. If the transom is too high the glass in the upper
lights can look ridiculously small. It's worth looking at windows in other
houses and in the showrooms if possible to take measurements. It would also
be worth doing a scale drawing of what you want to make sure it looks right.
