Thanks. All the sealed units have these terrible distortions and he tried a sealed unit from another manufacturer that he had used on another job (it wasn’t the correct size so he just held it by hand while i had a look) and they had the same distortions. So I don’t know what the solution is.

Ok so to make sure I understand, you’re saying all windows will likely have this distortion effect unless the ambient pressure happens to match that of the pressure inside the windows, but that with time this effect will reduce because of leaks which will enable older windows to equalise with...

Nothing unusual - about 300ft above sea level and the sealed units were produced in Preston, I believe. I don’t quite understand how the explanation from post #2 can be correct; surely if that were the case then all windows will appear distorted except on very rare occasions when the ambient...

Thanks that’s really helpful. My thoughts exactly on the plastic finish…. It may be something to do with Brewster’s fringes having the document. I may contact the Federation to see if they can advise.

So in your experience, the higher the “Low-e” rating, the more distortions? Is there a grade at which these distortions are no longer seen or are negligible?

These are argon filled windows. Any opinions on why the glass looks distorted? Is this normal? How can I get low-e glass that does not look distorted or wavy, like in the pictures?

Hello, thanks for the response. The glass is not toughened, but the inside glass has a low-e coating as you were saying. So are you saying this is a fault of the glass and that it’s not supposed to look like this? Is this likely a fault of the batch or do you think it’s normal for low-e glass?

Thanks Harry. But how does that explain the majority of neighbours’ and my own current house windows not looking distorted? Wouldn’t all double-glazed windows suffer if that were the main cause of the distortion?

I’ve ordered grade A double glazed windows and the way light and other objects, like overhead cables, reflect off the glass gives the impression that it is warped or wavy. For example the straight cables look like they bend in two directions. The neighbours windows don’t have this but there are...
