Labour would cost much more than the glass and not necessarily related to the area - there are many other variables. What is audio screen glass? Phone a glass supplier for a price.
It's all about labour. Ask the same supplier for prices on 10 full sheets, and the per-square-meter price will be dramatically lower. Plus, of course there is wastage when cut, as only a given number of windows can be cut out of a sheet - and they'll rarely have no waste.
Within the last two years I replaced three panes in the metal edged sliding units of one of our basement windows with a total area of two by eight feet = sixteen sq. feet or approx, 1.5 sq. metres. The glass company cut the (AFIK it was regular 4mm etc.) glass to the sizes needed measuring from the broken units then threw that old glass away. I picked up the glass panes and reassembled them into the metal edged sliders using the existing materaial. All told took me a couple of hours including picking up the glass and bringing it home. Total cost, including the cutting to size, IIRC was $36 (36 dollars Canadian including our sales tax) or roughly 16 quid. Glass is said to be somewaht expensive here; some 1500+ miles from the main population centres of North America! Transportation cost is a factor in everything we do, particularly housing/construction, especially since trucking involves an eight hour ferry connection in good weather with mainland Canada or every five day container ship from Montreal. Glass is also heavy.
All the now 35 year old windows in our house, comprise two sets of sliders each with single glass. In other words a typical window comprises two aluminium edged outer sliders and two inner sliders, in aluminium tracks, all set into a wooden (cedar or redwood) window box/frame built into the wood frame wall of the house. Half of full window size insect screens were included. These can also slide so as to be left or right; the only undesirable feature of which is that they mount on the outside edge of the outer tacks, meaning that they have to be removed (very easy job done from inside though) and stored each winter lest they get full of snow/ice. By contrast some other manufacturers windows 'store' the screens between the two sets of sliders.
Although this sounds cumbersome and not as tidy compared to, say, the 'sealed twindow' double glass unit 'picture window' as we have in our biggest four by eight foot main room window, these windows have worked out very well in this climate which is similar to but colder than the UK. The windows were manufactured locally from standard materials. Even in winter one set of sliders can be removed and or interchanged with the other set and/or cleaned flat on a table in a few minutes from inside the house; although as a one storey bungalow all 46 glass sliders (22 panes in basement and 24 panes main floor) windows are also accessible from outside.
The maximum any of our windows can be opened is to about half it's area. Or the two sets of sliders can be removed. this makes it very convenient for putting stuff through a window; planks, firewood chunks and or sheets of plywood etc. in/out the basement and furniture etc. a bedroom .
I'm renovating my sash windows, which have had 7mm thick glass put in for soundproofing (presumably). Can't tell you how much they cost, but I can tell you that they weight a lot, which will affect the windows and sash weights balancing.
No sales patter, he is a joiner that I have been having my sash windows made by for a year or so now. He makes the ones that are past help and I restore the others. I have just been wondering to myself lately if the price he has been charging is OTT or not. He specialises in making windows and supplies a major sash window company.
Yes they will do when I've fitted them, they will run like a dream like all my other restored ones :) The audio screen ones haven't actually been made yet. For the others that I've had done I use a simple formula to calculate the make weights required for these 4mm glass was used.
I want identical copies for the new windows and the double glazed options I have seen are not identical.
One bottom sash plus a top sash copy of original, a single glazing bar on each. pile carrier installed on the mid rail, each sash is about 100 cm x 80. Primed, no staff or parting bead, plus 7mm glass, he called it audio screen and I've heard this before. He is also making some adjustments to the rebate, not sure exactly in what way but its so the window can take 7mm glass.
Cost for 1 window (2 sashes) =A3600 + VAT
Does this sound reaonable? I have been paying in the past without questioning it but now the budget is running low for the rest of the renovations I'm needing to save some cash.
Hi Have you considered going to the major supplier that your joiner makes windows for and comparing what they charge and what he is charging you? Otherwise google for 7mm glas. BTW what are the complete specs per window. Is it just the sashes you are having remade?
No. It is a bloody good wage for a site joiner self employed working 6 days.
Why don't you take your next one apart and see how much needs replacing.
What I would do is just shove a couple of stock casements in the box and put a couple of nail-holes for the one I wanted to open as rquired to be supported by pegs as and when.
If he is using plain red pine stock timber and standard mouldings not copying exactly your mouldings (which he has the cutters for, in stock now, anyway) and any other specials, he's no better than the friend of one of the recent posters here who got a boiler replaced for an handsome exchange of shekels considering it was a "foreigner".
