Just have to get my wife back earning first!Most common recent DG unit thickness is 28mm (4-20-4) but remove one and measure it before ordering. When measuring H x W knock 10mm off both.
You'll be very happy with replacements. They'll offer a much better thermal value to the room. New units are filled with argon gas plus a K Glass (or other) on the outside. Get them ordered.
No, to change DG units requires extreme skill and years of experience. I doubt many people could carry out this task, it's just that I'm particularly awesome.
Only joking, it's fairly easy, However there's a few variables. If frames are timber, getting the timber glazing beads out carefully enough to re-use is the first tricky thing to overcome. Then removing old units can be a pest depending on how they've been installed. Some (fools) use putty with is totally wrong and usually the reason why the unit has failed (when the putty sets hard there's no room for the DG unit to expand and contract throughout the seasons). Glazing mastic is available and that allows DG unit to expand/contract without breaking the vacuum. Once you've removed the old unit and cleaned up the frame, fitting the new units is a relatively easy process.
Upvc frames are much less hassle but requires a bit more technique (ie replacing the beads) depending on which type of glazing profile it is. There are mostly 3 different ones.
Bet you're sorry you asked now eh???
- Externally beaded where the DG unit is held in place with double sided glazing tape. (adhered to window frame) Cut tape with a blade, remove beads, removed unit. (new tape is required before installing new unit)
- Externally beaded where there is a wedge gasket on the inside which MUST be removed before the beads are taken out. (otherwise the beads will just get damaged)
- Internally beaded (the most modern type) where the beads are removed and the units are taken out inside the house. This type is by far the easiest to install and to replace units.
P.S. The most common cause for DG units to fail in Upvc frames (in my experience) is poorly fitted units where the glazing packers are supporting BOTH panes of glass. In the extreme heat of Summer one pane 'slides' downwards breaking the vacuum.
I've got those green crystals at the bottom of the sandwich bit, are they old now?Most common recent DG unit thickness is 28mm (4-20-4) but remove one and measure it before ordering. When measuring H x W knock 10mm off both.

Looks great, I really like a lip spoiler, to my eyes it sharpens the rear end but is almost invisible.

34!!??
Are they as good as the hype? Might make a good 43rd wedding anniversary gift......
Yup. And that’s just the windows at the front and one side of the house. There are plenty more of a different type. I’m not quite as keen as Ant when it comes to cleaning them!
If 34 panels have broken down I dread to think how many there are in total!!
We haven’t got a palace! It’s 34 panels that are internally beaded, with about half a dozen failing. All the other DG panels are externally beaded and all fine.
