Replacement uPVC Glazing units and Beading

Dr4gul4

So, after much frustration over the last winter and some very helpful assistance from a well recommended local window installer it appears i have possibly two issues with my ten year old ( not purchased by me) windows.

The background !

Casement uPVC, double glazed, all handles and hinges etc in good working order and sealing tight.

It appears however, the beading is of poor quality, implementing only a single blade which compresses against the glass to prevent in bound air.
I can somewhat confirm this is the case, as i've ( over last winter) sealed the units in sheeting, taped along the outside of each bead, and watched as over a short period of time, said sheeting inflate as if it we're a hot air balloon .

Now i'm handy at most things, so cutting/ installing etc, not a huge issue, but sourcing is my real concern, if anybody has guidance on where to purchase, or how to measure/ identify the type of beading required i'd be only made up !

Second portion ! as the unit's are double glazed, again I've been reliably informed that replacement triple glazed units could be installed, and the associated costs while not pittance are some what low, given the return.
Assuming I measure up the glazing required, suggestions on where to order from would be super fantastic !


Answers on a postcard ( pm ) I guess.

Hi I am a glazier 20 years.and tbh I rarely come across bad PVC glazing beads.i am trying to understand your post and can possibly help.could you post some pictures of what you believe to be the problem.

Hey Massy,

I'll pop out a bead later on and snap some pics, the basic advice was the bead contained only a soft blade to compress against the glazing, where as the tear drop/ bubble applys more area of compression to prevent draught.

I've attached a blade and bubble version ( at least my understanding of them)

Could be solved by different internal rubber? Assume they’re externally beaded?

ye that was my thinking too or a glazing tape.there again if you where thinking of changing the glass you could get a thicker dg or tg unit.all options should push the glass closer to the beading and in turn compressing the rubber more to make a better seal

Would be a bit mad replacing all those units if they’re otherwise ok.

Given that windows are mass produced, as are the beads, it has to be an issue with the wrong wedge rubber or as you say the wrong glass.

I can’t see it being the bead.

I can only assume they are externally beaded also, Havent taken the big step of pulling out a section of glazing as of yet ..

Where does the internal rubber section sit ?

Changing the glazing is but an option, not really one i'd want to take up, as the windows are not even 10 years old, and while i dont expect them to be all signing all dancing, the quantity of cold air that breaches the frame is excessive.

What section is the dg/tg ?

how about some pictures of the actual windows, as requested in post 2?

Yikes, thought it was a request for the types of beading 🙈

Photography skills may not be up to spec, but can provide more .

Those look internally beaded to me. Any pics of the outside of the window please.

If they are internally beaded, the exterior rubbers should be keeping the wind out, it’s possible these have shrunk over time. I’ve seen a good few windows where whoever assembled them cut the rubber to length and didn’t allow for shrinkage. It should be possible to see the gaps in the corners if this is the case.

They are internally beaded.so wedge rubbers would not be an option.is it only opening windows that are mainly very draughty

It might still be using external (not wedge obvs) rubber as opposed to tape though. The likes of Profile 22 for example could use either.

Dr4gul4

Attached a few there, full shot, the lower split, and a corner section.

Hope that helps. I'm a touch lost on the lingo now already.

Just on this, no, the lower section as is draughty as the upper section. I've tested this by sealing off just said sections with tape + bag, and it inflated in no time

colm_mcm

There’s a big gap in the top left corner anyway by the looks of it?


Also, I’m not a doctor, but those drainage caps are upside down?

I'll blame the drainage caps on the wind so ..(nips out to rotate them all)

I assume the next stop would be to identify the profile of them and see if I can buy some new ones to cut and install ?

colm_mcm

I’d be inclined to just seal up the corners and see what happens.

(I’m not a glazer though, Massey086 will have the correct answer!)

In IMAG2724.jpg is that light colored strip on the outside a ruber

Based on some poke testing it does appears to be a rubber

Just had a look in a few other sections on other windows, and it appears to be almost peeling away from the glass a touch.

massy086

Ok maybe see if you can remove one corner with a flat scraper or flathead screw driver

colm_mcm

were the units ordered too thin and they used that ridiculously thick foam tape to fill the gap? There’s no way it’s meant to be like that?

Now of I attempt to remove this, are we export to slot back down inwards, it is on the external side of the windows #slightlynervious

Ah ya,ll be grand!!!!

That looks like a treble glaze frame old treble was quite thick with a double window

Are the double pane or single.?

Indeed it was, however news is not good, they seem to be inserted into the inside of the frame also.

Internal photo to follow

Can't be 100% sure but it looks to be one solid unit ?

Dr4gul4

Just a small nudge on this one to see if anybody has any wild follow up suggestions, like maybe, removing some glazing to have a proper look at said external rubber maybe .. or starting a small fire and claiming on the insurance.

I would remove the glass and from there see if the outside rubber was removable.and if so then post some pictures and I can try help you from there

One shall attempt said operation when the boss is not arround... And report back with photos

Dr4gul4

And we're back, with some possibly poor snaps, and some random codes.. the seal look to be in decent enough shape on the outside.. a touch perished perhaps, I'm more surprised to find all the screws on the internals frame ..altho perhaps this is the norm..

massy086

Hi have you still got the glass removed??.if so can you measure the tickness of the dg unit.it will be either 24mm or 28mm.slso did the outer seal push back into place easily

Minor issue there, the unit has been reinstalled, however, I could have a go on my own to remove it in a day or so, my assistant was a touch nervous during the entire process.

As for the seals, they came out of the channel with a little force, a small tug, and went back in smooth enough, seemed quite secure.

Measurement to follow tomorrow prob.

The measurement is not majorly important.what I would say is possibly take out glass again and take a seal off the frame and then refit the glass.then if you are Dublin based I would head over to a company called national seals.there are just off the naas rd.and see can they supply you with a thicker seal maybe just 2-3mm bigger . If they don't have the exact seal ask them for some samples of wedge gasket.maybe try 6mm 8mm and 10mm.a wedge gasget will just push in after the glass Hass been fitted.

Thank Massy, had a quick look on their www, I'll make the trip up mid week, not Dublin based but it's only an hour away..

Really appreciate the advice
