Anyone know owt about uPVC windows?

[EskiBrew]

I thought they had banned the companies frim putting the beads on the outside some time ago :wha:

 

[PD]

re beading. yes it happens we once had a house that was attacked by thiefs overnight, where they removed all the glass from the frames and stole that. Took the occupant several hours before he realise he had no glass in his windows !

Mind you on one new estate they stole the complete new lawn laid the previous day, just rolled it up and took it away...

Re externally beaded windows.....they are as strong as internally beaded as the retaining gasket is fed into the bead with a hard back on it and the glazing wedge inside thus making it as/more difficult to pull out than internally beaded plus externally beaded windows give you more design options and makes the glass sight line bigger because you dont have to reverse any of the frames to internal. :thumb:
I would go for ext beaded myself and i manufacture/fit these frames and have done for the last 14 yrs not heard of anyone get broken into so far (touches wood for luck)
And as the saying goes if theres a brick about they'll get in anyway.
Upvc was always ext beaded then came the time to make more money...scare people into thinking their house could be broken into so decided to reverse everything to internal things have come a long way in this industry now, some of the big players in aluminium fabrication and upvc push ext beaded for 'the look' they wouldnt do this if it wasnt secure they would go bust paying insurance companies for plasma tvs everyday!.
Although make sure you have a good reputable manufacturer or they could cut corners and not gasket the frames properly and make your window insecure.

Also, using silicone sealant anywhere near the outside edge of the sealed unit should be avoided; it attacks the butyl sealant around the edge of the unit, causing the seal to break down and fail prematurely (causes condensation within the cavity)

That's sounds way pricey to me :nono: :nono:

I am the worlds best haggler - call me Marvin - and I wanted an excellent local company to do my house and conservatory. They had done lots of work locally and as well as an impressive product - I knew where and how it was made at the time - their wormanship and cleanliness was exemplary.

They measured up, gave me the price and I just said no way I told them I wanted them to do the job, it was theirs for the taking, but the price had to be right

I knew what their margins were and waited until they knocked the price back down by two grand :shock:
to the price I was expecting :grin:

You've done the right thing asking on here - always do your homework when spending so much

Fair comment, but I wouldn't recommend silicone making contact with external bead or seal. I would only seal the glazed unit to the frame.

Or 4mm glazing tape, sticks like sh*t trust me!

I Can promise you this client of mine was broken into by exactly that method.

They prized out the seals and the glass panel and everything went out through the kitchen window! They very kindly left it all in a safe place so it could be refitted after.

I cant see the difference of inside or out, i have inside seals and it helps keeping them clean as there are no edges or cracks for moss to grow, But thats my choice and i dont want to scare everybody thats got external seals just fit locks on the downstairs window.

 

[bradford1982]

Im not doubting you for one minute my friend! I said I have never come across this from all the windows/doors ive manufactured and fitted and let me tell you in 14 years thats a hell of a lot! The external seals of said window will not have been hard backed or the internal wedge gasket will not have been big enough to comoress the glass to the external beads. Which re iterates my point get a good company to do your work!

 

[Sideboard]

How actually do you replace a glass unit without removing the external beads? and if you fitters can remove them, surely a criminal can.
Oh hang on I missed the part about inside wedge, does that lock the outside bead?

 

[bradford1982]

Yes the internal wedge compresses the bead on the outside and it locks into the frame. No amount of screwdrivers putty knives etc will get the beads out. Pvc the units are sometimes stuck on glazing tape which will make the glass stay there until you knife the inside all around

Thanks for your patience there. took some getting through to me. you guys are the ones to trust as your small enough to care(compared to everest etc) and big enough to do a great job. you won't last 14yrs in a trade doing a bad job.

 

[bradford1982]

i hope you are having a laugh!? Haha! :) i was only pointing you in the right direction. Experience is the key..............or so ive been told!?

hope you are having a laugh

If we all had someone like you to come round and do an honest job we would not have this thread.
Maybe this is why we have this thread? :thumb:

Hi Everyone,

I just thought I'd let you know how I ended up getting on with the windows, seeing as you were all good enough to advise me on the subject.

Initially I told the company I didn't want to pay that much and I thought I could get a comparable product elsewhere for less. They offered to send a guy round to discuss it with me as they said they really wanted our business. I told them that I didn't really want to mess about, if they wanted to give me their best price for the job then we would consider it and let them know. So the guy phoned me back half an hour later and said they would do the whole job for £5,250. We thought this was a good price so went ahead with it.

All the people we dealt with were spot on and seemed to know their product. Surveyor was very helpful and the fitters got the whole thing done in 2 days. It was 8 windows and a rock door, if you remember. Only minor issues with one window, loose handle, cracked silicone seal, were sorted a week later by the maintenance team.

So we're really happy.

Thanks again for everybodys help and input. Thanks also to Bradford for your offer.
