Hi
I have just had installed a large arched single double glazed upvc unit,
ground floor into stone wall

2410 wide 875mm high to curved section they n further 295mm in the curve
(so its oblong with curved corners and top.

The issue i have is that when its windy it creaks and make a squeeky
kind of sound, same when you gently push the glass either internally or
externally.

The glass is Pilks KS Optiwgite TUFF Swisspacer white Argon (copied from
spec sheet)

Can anyone tell me what thickness of glass should have been used and
what be causing the noise
Thanks for any help offered

I think you need to determine where the movement is.
Likely the draught seals rubbing on the frame If the window is
opening, maybe some silicon spray lubricant along where the draught
seals make contact with the frame.

Also lubricate any hinges/lock mechanism. The lock mechanism might
need adjusting to tighten things up a bit.
There is a sort of adjustable cam arrangement on most window locks.

I don't think there will be any problem with your glass.


Generally agree but could be between glass and seals even for a fixed
light. I'd try silicone spray here too. I'd guess the glass should be
reasonably thick at that size: maybe 4 or 6 mm?
