• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

And off to pastures new
Never having had any uPVC windows before in my life, we've got some of these at our new place. Is that drooping black thing 'fixable'?

TIA

An advert comes up on my FB feed of a company that if you post your seal to them, they will probably be able to match it and supply you with a new one.

Google - replacement DG seals or gaskets
 
That looks like it's inside the DG unit rather than the internal/external gaskets? I've not seen this happen before, but it looks like the powder coating has peeled off the aluminium extrusion around the inside of the unit, which basically means either you live with it or you replace the entire glazing unit. If the glazing isn't full of condensation, I personally wouldn't bother with messing with it as you'll likely do more damage to the window trying to get the glazing out than it's worth.
 
Hard to tell from the pics so Dan may be right, but it could just be the gasket between the dg unit and the frame. These can sag if they get hot but should push back in easily. You can remove them entirely for painting a frame without getting paint on the rubber, then press them back in.
 
I can't see glazing strips that you remove to take out the sealed unit so they must be on the outside which may be a bit of a security risk.

People say this all the time, but it's actually quite rare that someone goes through a window with externally beaded casements as it's a right pain to get the beads out and you make a hell of a racket doing it. Far more common is to smash a window that's next to a thumb turn or Yale lock and open a door.
 
Depends on the design of the glazing. We had a UPVC conservatory with external beading. I replaced a blown unit and was shocked how easy it was to remove the strips with just a screwdriver and lift the panel out. Conservatory is long gone now.

Dont most windows have the security tape also, which needs to be cut out.
 
The better units had either security clips or ahesive when externally glazed but internal beads are far betterIMO. I've fitted both types.

If that's inside the glazed unit Roger you only have two options, Live with it (I can't see your lovely wife putting up with that), or spend a few £100 quid to have it replaced, cost will depend on the size of the unit and also distance from the floor / any opening doors when it will need to be toughened glass. Any half decent glazier or doule glazing company will sort it and there are specialist repairers as well.
 
Wot Bob and Dan said. As far as I can see, your droopy wotsit is between two glass panes? New D/G glass ""cassette" Mucker. Just pray it ain't spreading to the other glazing.
Taking the retaining mouldings out is not a problem. Chisel, plaskit-headed hammer, two mins. Paying for the replacement cassettes am totally different! I've done it twice, but now have three large D/G ones with water leaks. I am asking for tenders on a kidney from Indian websites....
 
The grubby marks on the plastic that you have acquired can usually be removed with Cif btw.
The dg units aren’t difficult to replace but they do come in different thicknesses, there is a special tool used to measure without removing the unit but it’s not too difficult without it.
 
Roger, that is a spacer bar and looking at your one being black it is a " warm edge " spacer bar that provides better thermal separation between the glass. Cannot be repaired as it is within the sealed unit and so you just need a new unit which involves popping out the plastic trim which should be on the inside, if it is on the outside I would suggest replacing at least all the ground floor windows.
