Any point in upgrading glass in existing window frames?

[aveatry]

Great advice thanks - I’m not sure how thick my existing panes are but I reckon 22mm… won’t know until I take one out and measure.

Regarding cost I have seen this with what I was charged to have a couple of panes replaced with acoustic glass, I don’t think it would have been cheaper to buy and fit myself than to have a tradie supply and fit for me. I’ll need to do a bit more research.

At a minimum I’m replacing most handles as these are very worn, and gaskets. I took a sample gasket off today, I’m assuming by how flat it is that this is at end-of-life?

I forgot about those ones - I was referring to the main ones that hold in the glass. Yes some of those will also need replacing too. Again do the ebay sample set thing

I replaced all the glazing units in my 2003 built house when I moved in two years ago. Five had failed do I decided to change all.

I suggest souring any glazing units from a glazing manufacturer rather than doors, windows and conservatories installers.

As far as I'm aware, the modern glazing units are Argon gas filled.

Gasket seal and hinges are available on ebay.

Plenty of how to stuff on YT.

Yes the door and double glazing fitter just do the frames and they source their glass from a glazing manufacture. I go straight to the glazing supplier you should find a local one and the units are not as expensive as you might think.
One by one my origional units have failed and I replace them as and when.
Yes I think argon and warm edge glazing separators are now standard instead of the old silver ones that allowed transfer of cold from outside to inside.
I would recommend getting the coating on the glass, when I put my hand on a pane with it on it feels warmer than the non coated ones as its designed to reflect the heat into the room - so make sure you fit it the right way around.

Also what is the point in paying all of that out ( if you had them installed yourself ) in 2023 only to replace the whole lot - frames and all, with the idea of saving money on heating - how much would you of saved - well a typical 3 bed semi perhaps with 1 or 2 bays you are looking at £12,000 for the lot - so that is £600 per year over 20 years.
Maybe someone else can do the math but you are sold them on the basis of saving energy ( which I am all for ) but if you are replacing the whole lot every 20 years you dont save anything do you ?
But replacing the glass only and because you are allowed to do it DIY - unlike the frames makes much more sense.

I get door to door sellers. "oh I can see you have got UPVC windows - but how old are they" -- I will leave it to you to imagine my response
