Double Glazing Fix: Seals, Glass, Leaks & Replacing - Conservatory Renovation

How to renovate or fix upvc windows in a conservatory (or house). This video deals with typical things that go wrong or cause problems and how to fix them, like:
00:00 Intro
00:46 1) Rubber Seal Shrinkage - Gaps
00:59 2) Water in the Frame
01:38 3) New Rubber seals from eBay
01:54 4) Black Stains from Rubber UV Ageing
02:30 5) Replace the Glass or Repair? or Make single glazed?
04:34 6) Measuring up for New DGU (double glazed unit)
08:13 7) The Order of Fitting Rubber Seals
10:17 8) Why did the DGU blow?
13:40 9) Leaks Through Screws.
14:35 10) Single Glazed conversion
18:58 11) Water Penetration Sill & Walls
I replaced 4 double glazed glass units, changed all the rubber seals and converted 8 smaller windows to single glass pains in this conservatory. Converting from double to single pain glass pains is cost free and some may say unprofessional but for me the extra thermal insulation from double glazing on these small windows had no value, since the room got too hot in the summer when I forgot to open windows.
I bought the 4 new double glazed window panes online from buyglass.co for just over £300 with delivery and vat. (Feb 2024). Good service from them. I have no association with them and have had no payments or discounts for stating this. There are lots of local and other online suppliers, so search around.
So here are most of the other parts I used, from Amazon or eBay at the best prices and availability as I write this. Using these links will not cost you any more than going there without using these, but it does earn me some few coins.

My window beads come off from the outside, I'm never sure about the security. Good information thanks .

[@comeinhandynow]

Thanks for watching! Security is a bit weaker but it’s still a bit of a job to remove the window as on my externally beaded windows the inside has adhesive foam tape.

[@ericastier1646]

Sorry you showed removal of the seals (beads) with a rubber mallet and a spatula around to get to the glass unit and you said that to reinstall them their rubber ridges would not pop into place in the frame grooves easily, that you have to put them back first before re-installing the glass and that there would be enough gap to slide the glass over them. Forgive my incredulity but that sounds not easy to do at all. Could you reassure that step and give further guidance.

[@comeinhandynow]

That is a good point and for many years I thought like you are thinking that the reassembling order should be the same as disassembly..However after years of seeing the bead move out later all over the place, I realised that the reason and putting the bead in first is the solution and it works. Give the window a push into the frame to help compress the rubber. It works and the outer bead stays in place!

[@ericastier1646]

@@comeinhandynow thank you, it was worth asking and you gave the confident answer i was hoping for.

[@sekliw147]

Hi, i wonder if you could help pls? I took this small first unit out of oir conservatory. Stripped it down, cleaned glass throughly and used clear mastic to seal before gaffa taping all around. I struggled to get all the beading back in, but it misted up AGAIN within hours! Where did i go wrong pls? Tks v much. John

The desiccant inside the spacer bar is saturated with water, you would have to dry it out in an oven, replace it (messy as they are fine beads inside the spacer) or replace the spacer (difficult to get hold of small volumes). You also try putting the old spacer inside a very small room with a dehumidifier on max for a day or two.
