My wife bought a bungalow a few years.Â* The previous owners had
installed Everest double glazed windows. We could not visit the property
because of Covid restrictions but there is a camera in the sitting room
and we did notice that the blinds were moving on windy days.Â* I thought
that perhaps a window had been left open but when we were eventually
able to come here that was not the case. The all the Windows were made
by Everest.

The sitting room has a large window. The central glass panel is about 8'
wide by 6' high. The glass panel has an aluminium frame going round it
and was fitted from the outside into another aluminium frame that
attaches to a wooden frame.Â* Arround the outer aluminium frame there are
10 holes about 8mm in diameter. These holes allow access to small
posidrive screws which I think pull the glass aluminium frame towards
the aluminium frame in the wooden frame.

It is very unusual to have a window that can be easily dismantled from
the outside. I'd be surprised if that interpretation is correct.

The curtains were moving because one of the top corners of the glass
aluminium frame had come away outwards leaving about a half inch gap. It
could not be pushed back because one of the screws was catching on the
aluminium frame mounted in the wood.Â* I did just manage to get a
screwdriver into the screw and when I tried to turn it anticlockwise it
suddenly went further in and I was then able to push the glass and its
aluminium frame into the proper position though I can't secure it
properly. I can't see exactly what the screws do. If the window was much
smaller I could undo all the screws and then remove the glass and the
surrounding aluminium.

We had a couple of Everest double glazed windows in our home when we
bought it. The outer wooden frame a dark mahogany imitation and then an
aluminium white powder coated sub frame with the DG units mounted inside
that. I don't recall any external holes or posidrive screws on them. The
only thing that failed with age was the draft proofing spacer fur on the
opening window joints - apart from that they were rock solid. Eventually
replaced after one was punctured by a stone chip off the lawnmower and
the seal on the other went bad allowing water vapour in. I think they
had lasted 30+ years from installation which isn't at all bad.

So I am very unimpressed by Everest.Â* I don't understand why the window
would move outwards, the property is exposed to strong winds.

I think you need to show us photos of a good corner and the bad one.
Your description of the problem is very difficult to follow.

I am thinking about using pop rivets from the outside to hold the two
frames together.Â* It looks like some sort of glue was also used in the
orogial installation.

Or possibly a later attempted repair.

Any suggestions as to what else to try?

If you can understand why it has moved and twisted the way it has then
you stand a much better chance of repairing it permanently. A double
glazed window unit that size will be quite a heavy thing to manhandle.
