Condensation inside double glazing

Mikebyrne

Hi,

We're getting condensation inside the double glazing. Any idea how we can fix this??

I've attached a picture of it

Any help would be great!

The unit has broken down internally and needs to be replaced. Is it old? It might still be under warranty.

Open the window:

Measure the glass you have

Put back in the trim pieces

Order new glass

Put in when arrives, use the foam pieces that are stuck to the glass as packing to "lift up" the glass in the frame. Look at the one you are taking out to see how it was done.

So it's just a matter of replacing the glass?

It's a double glazed unit not just a sheet of glass. You need a new unit. Your one looks big so I wouldn't attempt doing what the guy on the video is doing I could see it ending in a dash to find a sheet of plywood before the next rain shower arrives. Some things are best left to the professionals.

Yeah it's simple, its two sheets of glass separated by an air gap. Not light but really easy for two people.

If its less than 1.5m sq you can do it alone no problem.

I've never heard of that arrangement before. Two of my windows suffered the same fate. I needed two new units. The two panes are bonded to the plastic centre section with the air sucked out making a complete sealed unit that's placed in the window frame.

Yeah I know, what I'm saying is its only 2 panes of glass that you are lifting!

You’ve got Georgian bars inside the glass too. Get a glazer in.

It's not necessarily an air gap . Some units, indeed most now, are Argon filled.
