Nearly 4 months ago my wife and I moved into our (new) home and
recently we have discovered that one on the double glazed window
sections has lost it's seal and is now opaque due to moisture ingress.
Anyone know of a company that can supply such sections without
replacing the whole window section?
We have no idea who made the windows originally and they have been in
approximately 5 years according to neighbours.
Any thoughts would be appreciated,
Oh well you must be thick! He means sections as in the bits of glass that
make up the whole area of glass to fit the frame. You can get an opening or
two, or divides.
Any double glazing company should help you out. It might also be possible
to repair and reseal that section depending on how bad the fault is. I
would pick a smaller company for this as the bigger ones will want to do all
the windows, doors, gutters, roof and god knows what else.
Why not look at carrying out a DIY repair to your existing glass, assuming
it is only suffering internal condensation....
I have heard of this method working quite well.
Take the panel out and put some suitable silicon sealant all the way around
the existing seal. Drill holes in opposite corners through the seal then use
a fish tank pump, one pump port connected to each of the holes to
recirculate the air through the panel. Get hold of some silica gell, put it
in a plastic box with a lid and cutting the pump pipe so the air flow passes
through the box. Silica gell will absorb all the moisture and it can be
revitalised by simply cooking the gell in an ordinary oven to dry it out.
Warming the glass will quicken up the process. After a few hours of this the
panel should be perfectly dry internally.
Seal up the two holes as you remove the pump pipework. If your glass is now
acceptably clear, look for a means to create a slight vacuum between the
panes of glass. Get hold of a large syringe needle, or some small bore pipe
and drill another hole which is a tight fit for the pipe. Evacuate the air
enough to create a reasonable negative pressure, then put a good blob of
sealant around the tube as you remove it, so it seals immediately the tube
is pulled out.
As someone else has said, go to a local small dg firm and ask their
advice. I did all my double glazing about 20 years ago and the frame
identity was type 22. For all I know, each frame type might vary, but I
have no idea. The company you go to will explain all this and also tell
you how to measure for a new double glazed unit (the glass bit).
I changed the glazing units in my lounge about 5 years ago for just the
same reason as you. As the main window is so large, they advised me to
choose thicker glass.
If this is of any use, the glazing bars should be on the inside. Remove
the rubber seal from the g / bar and then use a scraper, between the bar
and the frame to prise it out to remove the glazing bar and then put the
seal back into the g / bar, so as not to mix them up.
To refit the g / bar, I would recommend that your smear the seals with a
fairly strong solution of washing up water. Fit the glass and get
someone to hold it in place, smear the rubber with the water solution
and fit the shorter glazing bars first. Fit the corners into the frame
and you should end up with a bowed glazing bar. Using a bolster chisel
across the plane of the glass, get the bar to snap in. Work from both
ends and be prepared to use a lot more force than you think you will
need, to get the bar to go back into the frame. Bolster should be flat
against the window along it's length. Put a piece of card or thin wood
between the part of the bolster that you are going to hit, to prevent
any scratches to the glass. Then you can use this to slide the hammer
Providing you have ordered the right size of glass, you should be done
in around 30 minutes, unless you are working up a ladder.
It never ceases to amaze me on how dumb I can really be over these
I should have thought of Yellow Pages first and foremost, I am always
suggesting it to others!
My apologies to all, thankyou for the replies and suggestions.
Happy New Year, Peter.
